DESCRIPTION OF THE INVENTION
The following clearly describes technical solutions in embodiments of this application with reference to accompanying drawings in embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by a person of ordinary skill in the art based on embodiments of this application shall fall within the protection scope of this application.
The terms “first”, “second”, and the like in this specification and claims of this application are used to distinguish between similar objects instead of describing an order or sequence. It should be understood that the term used in such a way is interchangeable in proper circumstances, so that embodiments of this application can be implemented in an order other than the order illustrated or described herein. Objects classified by “first”, “second”, and the like are usually of a same type, and the number of objects is not limited. For example, there may be one or more first objects. In addition, in this specification and the claims, “and/or” represents at least one of connected objects, and a character “/” generally represents an “or” relationship between associated objects.
Usually, to obtain a photo with a good display effect, before photographing, a user may adjust, by using a photographing parameter control, a display effect of a preview image displayed on a photographing preview interface of a screen. Photographing parameters generally include: brightness, contrast, saturation, a hue, a zoom ratio, or the like.
However, with continuous upgrade of screen hardware of an electronic device, a conventional photographing parameter adjustment manner is single and fixed, which cannot adapt to continuous changes of the screen hardware, and flexibility is not high.
A scenario in which the technical solutions provided in embodiments of this application is applied may be determined based on an actual use requirement. This is not limited in this application.
For example, the technical solutions provided in embodiments of this application may be applied to a photographing scenario.
It is assumed that a zoom ratio in a current photographing scenario is adjusted as an example. Usually, if a photographing preview interface is displayed, if a user wants to adjust a zoom ratio corresponding to the photographing preview interface, the user may tap or slide on a zoom ratio adjustment control on the photographing preview interface, to adjust a current zoom ratio to a target zoom ratio.
Embodiments of this application are applied to a photographing apparatus having a scroll screen. If the user wants to adjust the zoom ratio in the current photographing scenario, after a first input performed by the user to the scroll screen is received, an unfolding parameter of the scroll screen can be determined based on the input of the user on the scroll screen, the target zoom ratio can be obtained based on the unfolding parameter of the scroll screen, and then photographing is performed based on the target zoom ratio, to obtain a target file. The target file includes at least one of the following: an image or a video. In this way, during a photographing process, the user can perform a corresponding input on the scroll screen and perform photographing based on different unfolding parameters, to obtain images or videos with different effects. Without a need to perform adjustment by using a photographing parameter control, a photographing parameter can be more directly and flexibly adjusted in embodiments of this application. This not only improves photographing efficiency, but also increases photographing fun.
With reference to the accompanying drawings, a photographing method and apparatus, and an electronic device provided in embodiments of this application are described in detail by using embodiments and application scenarios.
It should be noted that, the photographing method provided in embodiments of this application may be applied to a photographing apparatus having a scroll screen. For example, the photographing apparatus can be understood as an electronic device, or functional control or a functional unit in the electronic device, that is, the photographing apparatus is used in the electronic device.
An embodiment of this application provides a photographing method. FIG. 1 is a flowchart of the photographing method according to embodiments of this application. As shown in FIG. 1, the photographing method provided in embodiments of this application may include the following step 201 to step 203.

    
    
        Step 201: Receive a first input performed by a user to a scroll screen.
    
    


In embodiments of this application, the first input may be a touch input performed by the user to the scroll screen, or a voice command entered by the user, or a specific gesture entered by the user, and may be determined based on actual use requirements and is not limited in embodiments of this application.
For example, the touch input may be a tapping input performed by the user to the scroll screen. The specific gesture in embodiments of this application may be any one of a single-tapping gesture, a sliding gesture, a dragging gesture, a pressure recognition gesture, a long-press gesture, an area change gesture, a double-touch gesture, or a double-tapping gesture. The tapping input in embodiments of this application may be a single-tapping input, a double-tapping input, a tapping input for any quantity of times, or the like, or may also be a long-press input or a short-press input.
In embodiments of this application, the first input is an input for expanding and/or contracting the scroll screen.
In embodiments of this application, the photographing apparatus may receive the first input of the user while displaying a photographing preview interface.
It should be noted that this application is executed when an electronic device runs a camera application. In a scenario in which the electronic device runs the camera application in the foreground and in a photographing preview state, the technical solutions of this application may be executed.
In embodiments of this application, the photographing preview interface may be an image preview interface, or may be a video preview interface. This is not limited in embodiments of this application.

    
    
        Step 202: In response to the first input, obtain a photographing parameter based on an unfolding parameter of the scroll screen.
    
    


In embodiments of this application, the unfolding parameter is determined based on the first input. That is, the photographing apparatus determines the unfolding parameter of the scroll screen based on behavior of the user to expand and/or contract the scroll screen, and determines a photographing parameter of the preview interface based on the unfolding parameter of the scroll screen.
Optionally, in embodiments of this application, the unfolding parameter of the scroll screen includes an unfolding ratio or an unfolding length. For example, the unfolding ratio of the scroll screen is a ratio of the unfolding length of the scroll screen to a total screen length of the scroll screen.
Optionally, in embodiments of this application, the scroll screen includes two states: an expanded state and a contracted state. When the scroll screen is in the expanded state, the scroll screen includes a first screen region and a second screen region. When the scroll screen is in the contracted state, the scroll screen includes the first screen region, but does not include the second screen region (the second screen region is contracted to the inside of the electronic device).
Optionally, in embodiments of this application, the photographing parameter includes at least one of the following: a zoom ratio, contrast, brightness, a hue, a resolution ratio, or the like.

    
    
        Step 203: Perform photographing based on the photographing parameter, to obtain a target file, where the target file includes at least one of the following: an image or a video.
    
    


In embodiments of this application, after receiving the first input performed by the user to the scroll screen, the unfolding parameter of the scroll screen can be determined based on the input performed by the user to the scroll screen, a target zoom ratio can be obtained based on the unfolding parameter of the scroll screen, and then photographing is performed based on the target zoom ratio, to obtain the target file. The target file includes at least one of the following: the image or the video. In this way, during a photographing process, the user can perform a corresponding input on the scroll screen and perform photographing based on different unfolding parameters, to obtain images or videos with different effects. Without a need to perform adjustment by using a photographing parameter control, a photographing parameter can be more directly and flexibly adjusted in embodiments of this application. This not only improves photographing efficiency, but also increases photographing fun.
Optionally, in embodiments of this application, the following uses the photographing parameter as a zoom ratio as an example to describe the photographing method provided by embodiments of this application.
In some possible embodiments, a process of “obtain a photographing parameter based on an unfolding parameter of the scroll screen” in step 202 may include the following step 202a1.

    
    
        Step 202a1: Determine the target zoom ratio based on the unfolding parameter of the scroll screen.
    
    


With reference to step 202a1, a process of “perform photographing based on the photographing parameter, to obtain a target file” in step 203 may include the following step 203al. 

    
    
        Step 203a1: Perform photographing based on the target zoom ratio, to obtain the target file.
    
    


For example, after determining the target zoom ratio, the photographing apparatus may adjust a zoom ratio of a current photographing preview interface based on the target zoom ratio.
In this way, when the user wants to adjust the zoom ratio, the zoom ratio can be controlled by controlling the unfolding parameter of the scroll screen. This improves adjustment efficiency.
In some possible embodiments, before step 201, embodiments of this application may further include the following step 201b1.

    
    
        Step 201b1: Obtain a target zoom range based on a current zoom ratio.
    
    


The target zoom ratio is a zoom ratio within the target zoom range.
For example, after determining the target zoom range, the photographing apparatus may determine the target zoom ratio from the target zoom range with reference to the foregoing step 202a1 and step 203a1 and based on the unfolding parameter of the scroll screen, and then perform photographing based on the target zoom ratio, to obtain the target file. In one example, when the user wants to adjust the zoom ratio, the first input executed may be a continuous input, so that the zoom ratio can be flexibly adjusted within the target zoom range.
For example, when the user wants to adjust the zoom ratio, the photographing apparatus may obtain the current zoom ratio, and then determine the target zoom range based on a current unfolding ratio of the scroll screen. For example, a ratio range interval corresponding to the target zoom range is [L, R], where L is a current zoom ratio −K, and R is a current zoom ratio +K. It should be noted that the K value may be a fixed value (for example, 1), or may be flexibly set based on an actual requirement. This is not limited in embodiments of this application.
It should be noted that a zoom threshold corresponding to an interval boundary of the ratio range interval corresponding to the target zoom range belongs to a preset zoom range. That is, if a zoom threshold corresponding to the upper boundary of a ratio range interval determined based on the current zoom ratio exceeds a maximum value of the predetermined zoom range, the maximum value of the predetermined zoom range region is selected as the zoom threshold corresponding to the upper boundary. Otherwise, if the zoom threshold corresponding to the lower boundary of the ratio range interval determined based on the current zoom ratio exceeds a minimum value of the predetermined zoom range, the minimum value of the predetermined zoom range is selected as the zoom threshold corresponding to the lower boundary.
For example, it is assumed that a zoom range (that is, the foregoing predetermined zoom range) corresponding to the zoom ratio when the photographing apparatus performs photographing is [0.6×, 10×]. If the current zoom ratio is 1× and K is equal to 1, because 0 is less than 0.6×, the minimum value of the target zoom range is 0.6×. In this case, an accurate zoom control range (that is, the foregoing target zoom range) of the scroll screen is [0.6×, 2×]. If the current zoom ratio is 8.5×, the accurate zoom control range of the scroll screen is [7.5×, 9.5×]. If the current zoom ratio is 9.2×, because 10.2× is greater than 10×, the maximum value of the target zoom range is 10×, and the accurate zoom control range of the scroll screen is [8.2×, 10×].
For example, the photographing apparatus may control the zoom ratio by controlling the unfolding ratio of the scroll screen. Generally, the scroll screen 0% corresponds to a left boundary (that is, the lower boundary) of the ratio range interval corresponding to the target zoom range, and the scroll screen 100% corresponds to a right boundary (that is, the upper boundary) of the ratio range interval corresponding to the target zoom range. For example, that the target zoom range is 0.6×-2× is used as an example. The unfolding ratio 0% is corresponding to 0.6×; and the unfolding ratio 100% is corresponding to 2×.
It should be noted that, generally, the unfolding ratio of a scroll is [0%, 100%]. As shown in FIG. 2, the unfolding ratio is 0% when the scroll screen is completely closed. For example, a first display region of the scroll screen is completely contracted to a scroll 21, and a photographing preview interface 22 is displayed in a second display region. As shown in FIG. 3, the unfolding ratio is 100% when the scroll screen is completely expanded. For example, the first display region of the scroll screen is completely expanded, and the photographing preview interface 22 is displayed in the second display region.
In this way, when the user wants to adjust the zoom ratio, the zoom range may be reduced based on the current zoom ratio, so that the zoom ratio can be more precisely adjusted. This improves adjustment efficiency.
In some possible embodiments, a process of “perform photographing based on the photographing parameter, to obtain a target file” in step 203 may include the following step A1.

    
    
        Step A1: Perform photographing based on the photographing parameter and a zoom step, to obtain the target file.
    
    


For example, the zoom step may be a predetermined zoom step, or a zoom step manually selected by the user.
For example, with reference to the foregoing step A1, before the foregoing step 203, the photographing method provided in embodiments of this application may further include the following step A2 and step A3.

    
    
        Step A2: Receive a fourth input performed by the user to the photographing preview interface.
        Step A3: In response to the fourth input, determine the zoom step.
    
    


For example, the fourth input may be a touch input performed by the user to the scroll screen, or a voice command entered by the user, or a specific gesture entered by the user; and may be determined based on an actual use requirement. This is not limited in embodiments of this application.
In an example, the touch input may be a tapping input performed by the user to the scroll screen. The specific gesture in embodiments of this application may be any one of a single-tapping gesture, a sliding gesture, a dragging gesture, a pressure recognition gesture, a long-press gesture, an area change gesture, a double-touch gesture, or a double-tapping gesture. The tapping input in embodiments of this application may be a single-tapping input, a double-tapping input, a tapping input for any quantity of times, or the like, or may also be a long-press input or a short-press input.
In an example, N controls may be displayed on the photographing preview interface, and each control is corresponding to a zoom step. The user may use, by touching a target control (that is, one of the foregoing N controls), a zoom step corresponding to the target control as a zoom step to be used, for example, 0.1×, 0.05×, and 0.01×. A value of the zoom step is not limited in embodiments of this application.
For example, the photographing apparatus may further calculate the zoom ratio of the photographing preview interface based on the unfolding ratio of the scroll screen and a formula 1. The formula 1 is as follows: H+└a %*(R−L)/k┘*k, where H is the zoom ratio, the unfolding ratio of the scroll screen is a %, R is an upper boundary value of the target zoom range, L is a lower boundary value of the target zoom range, K is a target zoom step (that is, a set minimum zoom step), and └ ┘ indicates rounding off or rounding up and down.
For example, as shown in FIG. 2 and FIG. 4, when the unfolding ratio of the scroll screen is 56%, and the zoom step is set to 0.02×, the target zoom ratio is 0.6+[56%*(2−0.6)/0.02]*0.02=0.6+40*0.02=1.4, that is, 1.4×.
For example, when the unfolding ratio is 78%, and a default zoom step is 0.1×, the target zoom ratio is 0.6+[78%*(2−0.6)/0.1]*0.1=0.6+11*0.1=1.7×, that is, 1.7×.
In this way, when the user wants to adjust the zoom ratio, the user may select a proper zoom step, so that the zoom ratio can be adjusted based on a proper adjustment speed. This improves user experience.
In some possible embodiments, before step 203, the photographing method provided in embodiments may further include the following step C1 and step C2.

    
    
        Step C1: Receive a second input performed by the user to the scroll screen.
        Step C2: In response to the second input, obtain the target zoom region.
    
    


With reference to step C1 and step C2, a process of “perform photographing based on the photographing parameter, to obtain a target file” in step 203 may include the following step C3.

    
    
        Step C3: Perform photographing on a photographing object in the target zoom region based on the photographing parameter, to obtain the target file.
    
    


For example, step C1 may be performed before step 201, or may be performed after step 201. This is not limited in embodiments of this application.
For example, the second input is used to determine the target zoom region.
For example, the second input may be a touch input performed by the user to the scroll screen, or a voice command entered by the user, or a specific gesture entered by the user; and may be determined based on an actual use requirement. This is not limited in embodiments of this application.
For example, the touch input may be a tapping input performed by the user to the scroll screen. The specific gesture in embodiments of this application may be any one of a single-tapping gesture, a sliding gesture, a dragging gesture, a pressure recognition gesture, a long-press gesture, an area change gesture, a double-touch gesture, or a double-tapping gesture. The tapping input in embodiments of this application may be a single-tapping input, a double-tapping input, a tapping input for any quantity of times, or the like, or may also be a long-press input or a short-press input.
In an example, the scroll screen includes a screen region and a scroll region. For example, the scroll region of the scroll screen may be a scroll-type display, or may include a control component for controlling the scroll screen. The scroll region and a hardware form of the scroll are not limited in embodiments of this application.
The second input may be an input performed by the user to the scroll.
In an example, when step C2 is performed, the photographing apparatus may determine, in response to the second input, the target zoom region from the photographing preview interface based on a touch position of the second input.
For example, the target zoom region may be a part or all of the region of the photographing preview interface.
In some possible embodiments, before step 203, the photographing method provided in embodiments may further include the following step D1 and step D2.

    
    
        Step D1: Receive a third input performed by the user to the scroll screen.
        Step D2: In response to the third input, obtain a target zoom object.
    
    


With reference to step D1 and step D2, a process of “perform photographing based on the photographing parameter, to obtain a target file” in step 203 may include the following step D3.

    
    
        Step D: Perform photographing on the target zoom object based on the photographing parameter, to obtain the target file.
    
    


For example, step D1 may be performed before step 201, or may be performed after step 201. This is not limited in embodiments of this application.
For example, the third input is used to determine the target zoom object.
For example, the third input may be a touch input performed by the user to the scroll screen, or a voice command entered by the user, or a specific gesture entered by the user; and may be determined based on an actual use requirement. This is not limited in embodiments of this application.
For example, the touch input may be a tapping input performed by the user to the scroll screen. The specific gesture in embodiments of this application may be any one of a single-tapping gesture, a sliding gesture, a dragging gesture, a pressure recognition gesture, a long-press gesture, an area change gesture, a double-touch gesture, or a double-tapping gesture. The tapping input in embodiments of this application may be a single-tapping input, a double-tapping input, a tapping input for any quantity of times, or the like, or may also be a long-press input or a short-press input.
In an example, the scroll screen includes a screen region and a scroll region. For example, the scroll region of the scroll screen may be a scroll-type display, or may include a control region. The scroll region and a hardware form of the scroll are not limited in embodiments of this application.
The third input may be an input performed by the user to the scroll.
In an example, when step D2 is performed, the photographing apparatus may determine, in response to the third input, the target zoom object from the photographing preview interface based on a touch position of the third input.
For example, the target zoom object may be all or a part of photographing objects in a preview image displayed on the photographing preview interface.
For example, the zoom object may be a character, an animal, a building, a plant, or the like.
For example, that the third input is an input performed by the user to the scroll is used as an example. If the scroll of the scroll screen includes N second regions, and each region is corresponding to one object on the photographing preview interface, the third input includes: a touch input performed by the user to a target region on the scroll of the scroll screen. Similarly, that the second input is an input performed by the user to the scroll is used as an example. If the scroll of the scroll screen includes M second regions, and each region is corresponding to one region of the photographing preview interface, the second input includes a touch input performed by the user to a target region on the scroll of the scroll screen, where M is a positive integer.
It should be noted that the target region is at least one of the N second regions. The target zoom object is a zoom object corresponding to the target region, and the target zoom region is the target region.
For example, the second input or the third input may be a touch input performed by the user to the scroll (for example, a tapping input, a sliding input, and a press input). The foregoing tapping operation may be any quantity of tapping operations, or may be a long-press operation (a tapping time is greater than or equal to a preset time), or may be a short-press operation (a tapping time is less than the preset time), or the like. The foregoing sliding operation may be a sliding operation in any direction, for example, upward sliding, downward sliding, left sliding, right sliding, clockwise sliding, or anti-clockwise sliding.
For example, the foregoing target region may be one or more regions, that is, the user may select one or more zoom objects or zoom regions in a photographing preview region by touching one or more regions on the scroll of the scroll screen.
For example, the N second regions obtained through division of the scroll of the scroll screen may be evenly divided (that is, a region area of each second region is the same), or may be unevenly divided (that is, some of region areas of the N second regions may be the same or different). This is not limited in embodiments of this application.
For example, the N second regions may form all areas on the scroll of the scroll screen, or may form a part region (for example, an upper part of the scroll) in the scroll of the scroll screen. This is not limited in embodiments of this application.
For example, as shown in FIG. 5 and FIG. 6, it is assumed that the upper half of a scroll 31 of the scroll screen is divided into four regions, which are respectively: the upper left region, the upper right region, the lower left region, and the lower right region. The four regions respectively control the upper left region, the upper right region, the lower left region, and the lower right region of the photographing preview interface 32. For example, as shown in FIG. 5, if the user touches the upper left region of the scroll screen, a picture at the upper left position of the photographing preview interface 32 is enlarged. As shown in FIG. 6, if the user taps the lower right region of the scroll screen, a picture at the lower right position of the photographing preview interface 32 is enlarged.
It should be noted that when the user does not touch the scroll of the scroll screen, a center region of the photographing preview interface may be adjusted.
In this way, the scroll of the scroll screen is divided into a plurality of regions, so that the user can quickly select, based on a mapping relationship between the plurality of regions in the scroll screen and a plurality of objects on the photographing preview interface, a target object to perform adjustment. This improves adjustment efficiency.
It should be noted that the photographing method provided in embodiments of this application may be performed by a photographing apparatus or a control module, in the photographing apparatus, configured to perform the photographing method. In embodiments of this application, the photographing apparatus provided in embodiments of this application is described by taking that the photographing apparatus performs the photographing method as an example.
An embodiment of this application provides a photographing apparatus. The photographing apparatus includes a scroll screen. As shown in FIG. 7, the photographing apparatus 400 further includes: a receiving module 401 and an execution module 402.
The receiving module 401 is configured to receive a first input performed by a user to the scroll screen. The execution module 402 is configured to: in response to the first input received by the receiving module 401, obtain a photographing parameter based on an unfolding parameter of the scroll screen, where the unfolding parameter is determined based on the first input; and perform photographing based on the photographing parameter, to obtain a target file, where the target file includes at least one of the following: an image or a video.
In some possible embodiments, the unfolding parameters include an unfolding ratio or an unfolding length.
In the photographing apparatus provided by embodiments of this application, after receiving the first input performed by the user to the scroll screen, the unfolding parameter of the scroll screen can be determined based on the input performed by the user to the scroll screen, the photographing parameter can be obtained based on the unfolding parameter of the scroll screen, and then photographing is performed based on the photographing parameter, to obtain the target file. The target file includes at least one of the following: the image or the video. In this way, during a photographing process, the user can perform a corresponding input on the scroll screen and perform photographing based on different unfolding parameters, to obtain images or videos with different effects. Without a need to perform adjustment by using a photographing parameter control, a photographing parameter can be more directly and flexibly adjusted in embodiments of this application. This not only improves photographing efficiency, but also increases photographing fun.
In some possible embodiments, the execution module 402 is configured to:

    
    
        determine a target zoom ratio based on the unfolding parameter of the scroll screen; and
        perform photographing based on the target zoom ratio, to obtain the target file.
