And comparing the maximum zoom multiple passing through the target with the maximum zoom multiple being larger than a first preset multiple to determine the length of the initial zoom bar.

Specifically, the maximum zoom multiple of the target is greater than the first preset multiple, and if the maximum zoom multiple of the target is greater than the first preset multiple, the length of the distance between the minimum focus of the target corresponding to the minimum zoom multiple of the target and the first preset focus is determined to be the initial zoom bar.

The electronic equipment provided by the embodiment of the application takes the picture through the camera. For example, the electronic device may take a photograph through a single camera, or may take a photograph through multiple cameras, which is not limited in this regard. Wherein taking a photograph with a single camera may refer to the electronic device taking a photograph with a single camera 193; taking pictures with multiple cameras may refer to an electronic device taking pictures with multiple cameras 193 (e.g., two cameras, which may be a main camera and a portrait camera, or a wide-angle camera and a tele camera, etc.). The embodiment of the application is not particularly limited to a single-path camera shooting or a multi-path camera shooting, and a person skilled in the art can set the electronic equipment to select the single-path camera or the multi-path camera according to an actual scene.

When a user performs a touch operation on the touch sensor 180K, the touch sensor 180K may acquire the touch operation of the user and report the touch operation to the processor 110, and after receiving the touch operation transmitted by the touch sensor 180K, the processor 110 may respond to the touch operation and start an application corresponding to the touch operation.

As shown in fig. 3A, fig. 3A shows a schematic diagram of a user opening a camera application, for example, a user touch operation is to open a camera, the touch sensor 180K may receive a touch operation of the user on the camera icon 301 and report the touch operation of the camera icon 301 to the processor 110, after receiving the touch operation of the camera icon 301, the processor 110 may start an application corresponding to the camera icon 301 (may be simply referred to as a camera application) in response to the touch operation, and display a shooting preview interface of the camera on the display screen 194.

In addition, in the embodiment of the present application, the electronic device may also enable the camera application to be started in other manners, and display a shooting preview interface of the camera on the display screen 194. For example, the user may send a voice command to turn on the camera, the electronic device may report the received voice command to turn on the camera sent by the user to the processor 110 through the microphone 170C, and after receiving the voice command to turn on the camera sent by the user, the processor 110 may start the camera application in response to the voice command of the user, and display a shooting preview interface of the camera application on the display screen 194. Still alternatively, the user may store a shortcut instruction to open the camera in the electronic device in advance, for example, the shortcut instruction to open the camera may be set as an operation to touch the screen lower end of the electronic device to slide upward. When the user triggers a shortcut command for opening the camera, the touch sensor 180K may receive the shortcut command for opening the camera from the user and report the shortcut command to the processor 110, and after receiving the shortcut command, the processor 110 may start an application corresponding to the camera icon 301 in response to the shortcut command, and display a shooting preview interface of the camera on the display screen 194.

In some embodiments, the camera application may automatically enter the photographing mode after the processor 110 starts the camera application. As shown in fig. 3B, various functional controls, such as a mode selection control 302, a camera setup control 303, and the like, may be included on the capture preview interface of the camera application. The touch sensor 180K may receive a touch operation of the user on the functional control, and report the touch operation to the processor 110, so that the processor 110 controls the camera application to enter the corresponding interface in response to the touch operation. In some examples, the user may trigger the camera application to enter a different shooting mode, such as a night view mode, a tele mode, etc., and a rainy mode, a snowy mode, etc., via the mode selection control 302. The functions such as a filter, watermark, panorama and the like can be started through the camera setting control 303. For example, the user may set an initial mode of the camera application to a photographing mode through the camera setting control 303, and when the user reopens the camera application again, the camera application automatically enters the photographing mode. The initial mode of the camera application may also be set to a record mode by the camera setup control 303, and the camera application automatically enters the record mode when the user reopens the camera application again.

In some embodiments, after the camera application automatically enters the photographing mode, the camera application may display zoom points in the photographing preview interface, such as a zoom point diagram in the photographing preview interface of the camera application shown in fig. 3C, where each zoom point represents a zoom multiple, for example, clicking on numeral 1 in the camera application, displaying 1×inthe photographing preview interface of the camera application, that is, representing zoom by a factor of 2, clicking on numeral 5 in the camera application, displaying 5×inthe photographing preview interface of the camera application, that is, representing zoom by a factor of 5, and so on. The touch sensor 180K may acquire the operation of clicking the zoom point triggered by the user and report the operation to the processor 110, and the processor 110 may control the camera application to display to the corresponding zoom point according to the operation of clicking the zoom point triggered by the user, so as to implement zooming of the camera application. In some embodiments, as shown in fig. 3D, where the zoom bar is schematically displayed in the camera application shooting preview interface, the touch sensor 180K may also obtain an operation of the user to press the zoom control 309 long or to pull the zoom component 309A in the zoom control 309, and report the operation to the processor 110, and the processor 110 may control the camera application to display a zoom bar composed of zoom points. Meanwhile, the camera application can be controlled to display the adjusted zoom multiple according to the operation of pulling the zoom component 309A in the zoom control 309 by a user, for example, the zoom component 309A in the zoom control 309 can be pulled to adjust the zoom multiple from 1 to 1.6 times, the zoom component 309A in the zoom control 309 can be pulled to adjust the zoom multiple from 1.6 to 2 times, and the like, so that the user can know the current zoom multiple of the camera application. The camera application may also automatically enter a video mode in which the user may adjust the zoom factor of the camera application.

In some embodiments, after determining the zoom multiple of the camera application, the user may trigger a photo taking operation through a touch capture key 304 in a photo preview interface of the camera application, and when the user triggers the photo taking operation, the touch sensor 180K may acquire the photo taking operation triggered by the user and report the photo taking operation to the processor 110, and the processor 110 may control the camera application to take a photo and may acquire a photo taking time and a photo taking place of the photo taking operation triggered by the user. The photographing time may be a time corresponding to when the user touches the photographing key 304 to trigger a photographing operation. The photographing place may be a geographical position of the electronic device when the user touches the photographing key 304 to trigger the photographing operation, and further, the user may also set a time delay photographing time of the camera application in the electronic device through the camera setting control 303, for example, the time delay photographing time may be set to be 3 seconds, 5 seconds, 10 seconds, etc., where the time delay photographing time refers to photographing after triggering the photographing operation of the camera application for a certain time.

In the following, taking the delay time set to 3 seconds as an example, firstly, the user can set the delay photographing time of the electronic device to 3 seconds through the camera setting control 303, the electronic device can acquire the operation of setting the delay photographing time of the user on the screen of the electronic device through the touch sensor 180K, and transmit the operation to the processor 110, and the processor 110 can store the 3-second delay photographing time set by the user. When the user triggers the photo taking operation, the touch sensor 180K may acquire the photo taking operation triggered by the user and report the photo taking operation to the processor 110, and the processor 110 may control the camera application to count down, as shown in fig. 3E, which shows a count down schematic diagram of the camera application in the process of taking a photo, and the processor 110 may control the count down number of the camera application to be displayed in the screen of the electronic device, so that the user may intuitively acquire the count down information. In response to the processor 110 determining that the 3 second countdown is over, that is, the countdown time meets the delay time set by the user, the processor 110 may control the camera application to take a photograph, so that by setting the delay time, the problem that no other person takes a photograph in some scenes may be solved. Wherein other persons may refer to persons who do not need to appear in the photograph.

In some embodiments, the camera application may trigger the photo taking operation by means of gesture taking, voice taking, and the like, in addition to the photo taking operation by touching the photographing key 304. The gesture photographing refers to that the camera application triggers a photo taking operation by identifying a photographing gesture set by a user, and the sound photographing refers to that the camera application triggers the photo taking operation by identifying a sound set by the user. Specifically, as shown in a schematic diagram of a photographing mode setting shown in fig. 3F, after the user clicks the camera setting control 303, the photographing mode control 305 may be displayed in the camera application, and clicking the photographing mode control 305 may display gesture photographing and sound photographing. Further, the user may autonomously set a photographing gesture for triggering the photographing operation and/or a user sound for triggering the photographing operation according to the needs, for example, gesture photographing is performed by taking a specific gesture set by the user as an example, the user may set a specific gesture in a camera application to trigger the photographing operation, when the user needs to photograph, the user may put out the specific gesture, the electronic device may process a front camera or a rear camera in the camera 193 to transmit the obtained light to the photosensitive element of the camera through the lens, convert the light signal into an electrical signal through the photosensitive element, transmit the electrical signal to the ISP to process, and the ISP transmits the processed data to the processor 110, so that the processor 110 may determine that the user triggers the photographing operation to control the camera application to photograph.

The voice photographing takes the user setting recognition voice as a photographing example, when the user needs to photograph, the user can speak the voice of the photographing word, the microphone 170C can acquire the voice of the user, the voice is transmitted to the processor 110 after being processed by the signal, and the processor 110 can determine that the user triggers photographing operation to control the camera application to photograph.

In order to avoid that the function keys on the screen block the scene image displayed by the camera application in the process of taking the photo, so that the user experience is poor, the touch sensor 180K can acquire the operation triggered by the user and report the operation to the processor 110, the processor 110 can hide the mode selection control 302 of the camera application in the process of taking the photo according to the operation of the user, as shown in fig. 4A, in some examples, in the process of previewing the scene image displayed by the camera, the operation of the user can be a touch screen, the touch sensor 180K acquires the operation touched by the user and reports the operation to the processor 110, and the processor 110 hides the mode selection control 302 of the camera application in the process of taking the photo, so that the image is not blocked and displayed in the screen of the electronic device, so as to improve the experience of the user.

Currently, the zoom bars in camera applications are equally divided among various zoom points, so that a user cannot quickly adjust the zoom factors to the zoom factors required by the user, and the user operation is not facilitated.

In order to make the technical scheme of the application clearer and easier to understand, the zoom bar dividing method provided by the embodiment of the application is described below with reference to the embodiment and the corresponding drawings. The method can be implemented on an electronic device with the structure shown in fig. 1, wherein the electronic device comprises a camera, a microphone and a display screen. See a flow chart of a zoom bar segmentation method shown in fig. 5. As shown in fig. 5, the zoom bar segmentation method provided by the embodiment of the present application may include:

s501: the camera application is started.

In some examples, when a user needs to use a camera application of the electronic device (e.g., take a photograph or record a video, etc.), the user may click on the camera icon 301 shown in fig. 3A, and after the electronic device detects that the user clicks on the camera icon 301, the electronic device starts the camera application. In other examples, the user may cause the electronic device to launch the camera application in other ways as well. For example, by voice commands or other preset gestures, etc., embodiments of the present application are not limited in this regard.

S502: a photographing mode of the camera application is determined.

After the electronic device starts the camera application, a preset photographing mode can be entered, taking a common photographing mode as an example, the zooming multiple of the common photographing mode can be defaulted to be 1 time, and a video stream can be acquired through the camera so as to display a preview scene image on a photographing preview interface. In some embodiments, the camera of the electronic device may be a single-path camera, and the electronic device may default to a single-path photographing mode, that is, the electronic device obtains a single-path video stream through the single-path camera; in other embodiments, the camera of the electronic device may be a multi-path camera, and the electronic device default photographing mode is a multi-path photographing mode, so that the multi-path video stream may be acquired through the multi-path camera. For example, the electronic device may obtain the first video stream through the first camera and obtain the second video stream through the second camera, and of course, the electronic device may also obtain the third video stream through the third camera. Taking an example that the multi-path camera comprises two paths of cameras, the first path of camera can be a main shooting sceneShooting and photographing deviceThe camera, the second path camera can be a wide-angle camera or a camera with other functions, and the embodiment of the application does not limit the application 。

In some embodiments, the electronic device may further receive a switching operation triggered by the user, where the switching operation is used to instruct the electronic device to switch the photographing mode of the camera. For example, when the camera shooting mode is the single-path shooting mode, the user may trigger the electronic device display control 307 by clicking the camera shooting mode in the control 305 in fig. 3G, and the multi-path shooting mode control electronic device in the control 307 may trigger the electronic device display control 308 when the user clicks the multi-path shooting mode control, and further the user may trigger the switching operation through the touch control 308, and the electronic device switches the single-path shooting mode of the camera application into the multi-path shooting mode in response to the switching operation triggered by the user. For another example, when the camera shooting mode is the multi-path shooting mode, the user may trigger a switching operation by clicking the camera mode in the control 305 of fig. 3G, and the electronic device switches the multi-path shooting mode of the camera application to the single-path shooting mode in response to the switching operation triggered by the user. The multi-path shooting mode refers to shooting of photos through cooperation of a plurality of cameras. The multi-path photographing mode can comprise a main photographing extended focus mode, a main photographing extended wide angle mode, a main photographing extended portrait mode and the like, and the electronic equipment can also respond to switching operation triggered by a user to perform random switching in the multi-path photographing mode so as to meet the requirements of the user.

S503: and determining the target zoom multiple according to the photographing mode.

The zoom factor refers to the electronic device increasing or decreasing the area of each pixel within the preview scene image displayed in the preview interface by the processor 110, thereby achieving the purpose of enlarging or reducing the image. It will be appreciated that the preview scene image may be enlarged or reduced by a multiple of the zoom factor, with the larger zoom factor increasing the area of each pixel within the preview scene image by a multiple and the smaller zoom factor decreasing the area of each pixel within the preview scene image by a multiple. The maximum zoom factor refers to the maximum factor that allows each pixel area within the preview scene image to be magnified.

In some embodiments, after determining the photographing mode, the target zoom multiple may be determined according to a correspondence between the photographing mode and the target zoom multiple, where the target zoom multiple may include a target maximum zoom multiple and a target minimum zoom multiple, taking the normal photographing mode in the single-path photographing mode as an example, a zoom range of the normal photographing mode may be preset to be 1-10 times, that is, the correspondence between the normal mode and the target zoom multiple may be preset to be 10 times the maximum zoom multiple and 1 time the minimum zoom multiple of the normal mode. When the photographing mode is determined to be the common photographing mode, the maximum zoom multiple and the minimum zoom multiple of the camera applied in the common mode can be determined. For another example, taking a video mode in a single-path shooting mode as an example, the zoom range of the video mode may be preset to be 1-15 times, that is, the maximum zoom factor of the video mode is preset to be 15 times, the minimum zoom factor is preset to be 1 time, and when the shooting mode is determined to be the video mode, the maximum zoom factor of the camera applied in the video mode may be determined to be 15 times, and the minimum zoom factor is determined to be 1 time according to the corresponding relation of the video mode.

In some embodiments, in order to meet the user requirement, the maximum zoom multiple may be preset to be less than 1 time, for example, the user needs to take a picture wider in the wide-angle mode, the zoom range of the wide-angle mode may be preset to be 0.5 time to 1 time, and when the photographing mode is determined to be the wide-angle mode, the maximum zoom multiple may be determined to be 1 time, and the minimum zoom multiple may be determined to be 0.5 time.

S504: and determining the initial zoom bar length according to the target zoom multiple and dividing the initial zoom bar.

The maximum zoom multiple corresponding to the target mode can be compared with a first preset multiple, so that under different conditions, the initial zoom bar is divided into a plurality of segments with different length ratios according to preset division rules, and each segment is divided according to the division ratio corresponding to the preset division rules. Wherein the first preset multiple may be 2.

The following description will be made in different cases.

Case one:

in some embodiments, when the maximum zoom factor is greater than the first preset factor by a factor of 2, less than or equal to 10, the distance between the 1-fold zoom point and the 10-fold zoom point may be determined, thereby determining the length of the initial zoom bar. For example, a distance between the 1-fold and 10-fold zoom points may be preset to 180dp, so that the initial zoom bar may be determined with the 1-fold and 10-fold zoom points at both ends, 180dp being the length, wherein the preset distance may be characterized in units of device-independent pixels (dp, device independent pixels).

Further, as shown in fig. 4B, the zoom bar may be divided according to a preset first division rule according to a scale in the drawing and positions of 2-fold and 5-fold focal points may be determined on the initial zoom bar. Specifically, the initial zoom bar may be divided into three sections, wherein the first section length, that is, the distance between the 1-fold focal point and the 2-fold focal point may be 0.38 times the total length of the initial zoom bar, the second section length, that is, the distance between the 2-fold focal point and the 5-fold focal point may be 0.37 times the total length of the initial zoom bar, and the third section length, that is, the distance between the 5-fold focal point and the 10-fold focal point may be 0.25 times the total length of the initial zoom bar. After determining the positions of the 2-fold and 5-fold zoom points, the initial zoom bar may be further divided according to a division ratio corresponding to the first division rule, as shown in fig. 4C, a distance between the 1-fold and 2-fold zoom points may be referred to as a first distance, the length between the first distances may be 1, the first distance may be equally divided into 10 parts in units of 0.1, each part may occupy 0.1 times of the first distance, a division line may be marked every 0.1, each corresponding division line may represent one zoom multiple, and it may be understood that the zoom multiple between every two adjacent division lines in the first distance differs by 0.1. Meanwhile, the distance between the 2-time zoom point and the 5-time zoom point can be called a second distance, the length of the second distance is 3, the second distance can be equally divided into 12 parts in units of 0.25, one dividing line can be marked every 0.25, and the zoom multiple difference between every two adjacent dividing lines in the second distance is 0.25. The distance between the 5-time zoom point and the 10-time zoom point may be referred to as a third distance, the length of the third distance may be 5, the third distance may be equally divided into 10 parts in units of 0.5, each part may be 0.1 times the third distance, one division line may be marked every 0.5, and the zoom multiple difference between every two adjacent division lines in the third distance may be 0.5, so that the division of the initial zoom bar may be completed. Thereby determining a split zoom bar shown in the camera application. When the user needs to adjust the zoom multiple, the touch sensor 180K may acquire the operation of the user to press the zoom control 309 for a long time or pull the zoom component 309A in the zoom control 309, and report the operation to the processor 110, and the processor 110 may control the camera application to display the zoom point determined according to the user operation on the segmented zoom bar, for example, as shown in fig. 4D, the user adjusts the zoom multiple to 3.5 times according to the requirement, and the processor 110 receives the user operation reported by the touch sensor 180K, and controls the camera application to display the zoom multiple 3.5 on the segmented zoom bar. The embodiment can complete the division of the zoom bar, and then display the zoom point multiple reported according to the user operation on the zoom bar after the division. The zoom magnification reported according to the user operation may be acquired first, and then the zoom bar may be divided according to the reported zoom magnification, as described in the following embodiment in the second case.

And a second case:

in some embodiments, the maximum zoom magnification is greater than the first preset magnification by a factor of 2, less than or equal to 10, the distance between the 1-fold focal point and the 10-fold focal point is determined to be the length of the initial zoom bar, for example, the distance between the 1-fold focal point and the 10-fold focal point may be preset to 180dp, as shown in fig. 4E, the zoom bar may be initially divided according to the golden section law according to the scale in the figure, and the positions of the 2-fold focal point and the 5-fold focal point may be determined on the initial zoom bar. Specifically, the initial zoom bar may be divided into three sections, wherein the first section length, that is, the distance between the 1-fold focal point and the 2-fold focal point may be 0.25 times the total length of the initial zoom bar, the second section length, that is, the distance between the 2-fold focal point and the 5-fold focal point may be 0.425 times the total length of the initial zoom bar, and the third section length, that is, the distance between the 5-fold focal point and the 10-fold focal point may be 0.325 times the total length of the initial zoom bar. After determining the positions of the 2-fold and 5-fold variable focal points, the initial zoom bar may be further divided, as shown in fig. 4F, and the second segment length is equally divided into three, so that the positions of the 3-fold and 4-fold variable focal points on the initial zoom bar may be determined. The third segment length is equally divided into 5 parts, and the positions of the 6-fold, 7-fold, 8-fold, and 9-fold zoom points on the initial zoom bar can be determined. For comparison with the reported multiple of the variable focus. When the user needs to adjust the zoom multiple, the processor 110 may receive the user operation reported by the touch sensor 180K, and further control the camera application to display the zoom point determined according to the user operation on the zoom bar after the preliminary segmentation. The following describes the case in two ways into two application scenarios in detail.

The first application scenario of case two:

in some embodiments, the zoom point on the displayed zoom bar may be determined based on a user-operated determined zoom point, or may be referred to as a first zoom point. Specifically, when the reported zoom point, that is, the zoom point determined according to the user operation, the multiple is smaller than a second preset multiple, where the second preset multiple is exemplified by 4 times, and of course, other multiples may also be used. Only the minimum focus, the maximum focus, the intermediate focus and the reported focus may be displayed on the zoom bar. Specifically, if the first variable focus is determined to be smaller than the second preset multiple, the middle variable focus is determined to be the first multiple variable focus, and if the first variable focus is determined to be larger than or equal to the second preset multiple, the middle variable focus is determined to be the second multiple variable focus. Wherein, the first multiple variable focus point can take 5 as an example, and the second multiple variable focus point can take 4 as an example. Further, the length of the distance between the minimum focal point and the intermediate focal point on the initial zoom bar may be divided according to a preset first ratio, and the length of the distance between the intermediate focal point and the first preset focal point on the initial zoom bar may be divided according to a preset second ratio, where the first preset focal point may be 10, the first ratio may be exemplified by 0.25, and the second ratio may be exemplified by 0.5. That is, the minimum variable focus point and the intermediate variable focus point may be divided in units of 0.25, and the intermediate variable focus point and the maximum variable focus point may be divided in units of 0.5. As shown in fig. 4G, taking the reported zoom point of 2 times, the minimum zoom point of 1 time, and the maximum zoom point of 10 times as examples, 1 time, 2 time, 5 time, and 10 time zoom points can be displayed on the zoom bar, wherein the length of the distance between 1 time and 5 time zoom points is 4, and the length of the distance between 5 time and 10 time zoom points is 5. The length of the distance between the 1-fold variable focus and the 5-fold variable focus is divided in units of 0.25, every 0.25, and the length of the distance between the 5-fold variable focus and the 10-fold variable focus is divided in units of 0.5, every 0.5. To complete the segmentation of the zoom bar.

Second application scenario of case two:

in some embodiments, when the reported focal point, that is, the zoom point determined according to the user operation, is greater than or equal to the second preset multiple 4, only the minimum focal point, the maximum focal point, the intermediate focal point, and the reported focal point may be displayed on the zoom bar. The minimum variable focus and the intermediate variable focus can be divided according to 0.25 unit, the intermediate variable focus and the maximum variable focus can be divided according to 0.5 unit, the intermediate variable focus can be set as 4 times of variable focus, and the variable focus can be other times of variable focus. As shown in fig. 4H, taking the reported zoom point of 4 times, the reported minimum zoom point of 1 time and the reported maximum zoom point of 10 times as examples, the zoom bar can display 1 time, 4 time and 10 time of zoom points, and in order to facilitate the user to more intuitively understand the current zoom multiple, the zoom point of 2 times can also be displayed, wherein the length of the distance between the 1 time of zoom point and the 4 time of zoom point is 3, and the length of the distance between the 4 time of zoom point and the 10 time of zoom point is 6. The length of the distance between the 1-fold variable focus and the 4-fold variable focus may be divided in units of 0.25, divided every 0.25, and the length of the distance between the 4-fold variable focus and the 10-fold variable focus may be divided in units of 0.5, divided every 0.5. To complete the segmentation of the zoom bar.

And a third case:

in some embodiments, when the maximum zoom multiple is less than or equal to 2 times of the first preset multiple, determining that the distance between the 1-time zoom point and the second preset zoom point is the length of the initial zoom bar, wherein the second preset zoom point may be the 2-time zoom point, and dividing the initial zoom bar into a plurality of segments with different length ratios according to a preset second division rule;

for example, the distance between the 1-fold zoom point and the 2-fold zoom point may be preset to be 0.7 times the distance between the 1-fold zoom point and the 10-fold zoom point in the above-described embodiment. The length of the initial zoom bar may be divided into 2 parts, as shown in fig. 4I, the first distance may be a distance between 1 time of the zoom point and the zoom point corresponding to the middle scale line, the second distance may be a distance between the zoom point corresponding to the middle scale line pair and 2 times of the zoom point, the first distance may be 0.572 of the length of the initial zoom bar, and the second distance may be 0.428 of the length of the initial zoom bar. The middle graduation mark can be marked as 1.5, and can be marked as other numbers. And then, the zoom bar can be further segmented, each of the plurality of segments is equally segmented according to the segmentation proportion corresponding to the second segmentation rule, and a third zoom bar is obtained. For example, the first distance and the second distance may be equally divided into 10 parts, respectively, to complete the division of the zoom bar.

Case four:

in some embodiments, for example where the minimum magnification is less than 1 time in the wide angle mode, the length of the distance between the minimum magnification and the 1-time zoom point may be determined, for example, with the minimum magnification being 0.5 times and the length of the distance between the minimum magnification and the 1-time zoom point being 50 dp. The zoom point corresponding to the minimum zoom multiple, namely, the length 50dp of the distance between the 0.5-time zoom point and the 1-time zoom point can be equally divided into 5 parts according to 10dp of each part, so that the division of the zoom bar between the minimum zoom multiple and the 1-time zoom point is completed.

Case five:

in some embodiments, for example in tele mode, the maximum magnification is greater than 10 times, the length of the distance between the intermediate variable focus and the intermediate variable focus may be determined, the length of the distance between the intermediate variable focus and the maximum variable focus may be determined, for example taking the intermediate variable focus as 50 times the variable focus, the maximum variable focus as 100 times the variable focus, the length of the distance between the 10 times the variable focus and the intermediate variable focus as 50dp, and the length of the distance between the intermediate variable focus and the maximum variable focus as 44dp as an example. The length 50dp of the distance between the 10-fold zoom point and the 50-fold zoom point is equally divided into 10 parts, and the length 44dp of the distance between the 50-fold zoom point and the 100-fold zoom point is equally divided into 10 parts, thereby completing the division of the zoom bar between the 10-fold zoom point and the maximum zoom point.

According to the embodiment provided by the application, the target zoom multiple corresponding to the target mode can be determined according to the determined target mode and the corresponding relation between the preset photographing mode and the zoom multiple, the initial zoom bar is determined according to the target zoom multiple, then the initial zoom bar is segmented according to the corresponding preset segmentation rules under different conditions of different modes, a plurality of segments with different length ratios and corresponding segmentation ratios according to the preset segmentation rules are obtained, so that the zoom area commonly used by a user in the zoom bar can be finely segmented, the very-used zoom area of the user can be briefly segmented, the user requirements can be met, and the user operation is convenient.

In the above-described embodiments, after the zoom bar is divided, the size of the zoom bar, the transparency gradation specification of the zoom bar, the color of the scale line in the zoom bar, the format of the text in the zoom bar, and the like may be adjusted according to the operation of the user.
