[0055] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0056] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0057] In the related art, when a user presses a camera button of a terminal, a single fixed-magnification image is generated. The fixed-magnification image may be a 1x image or the magnification saved when the user last exited the camera.

[0058] If the user wants to adjust the image magnification when shooting, the moment they want to shoot may be missed when adjusting the image magnification. For example, when the user is shooting a distant object such as a vehicle and adjusts the image magnification from 1x to 2x, the vehicle may have moved out of the field of view while the user is adjusting the image magnification from 1x to 2x, and the user will not be able to shoot the vehicle.

[0059] If the user does not adjust the image magnification, the captured image may have poor image quality, and the generated image may not meet the user's expectations, thus failing to meet the user's needs. For example, when a user uses a fixed magnification of 0.6 to shoot a distant vehicle, since the vehicle is small in the image, the user may enlarge the image and crop it to display the distant vehicle. However, after the image is enlarged and cropped, the clarity will be reduced, resulting in a blurry displayed vehicle, thus failing to meet the user's demand for image clarity.

[0060] Based on this, the present disclosure proposes an image processing method. Figure 1 is a flowchart of an image processing method according to an exemplary embodiment. Figure 1 As shown, the image processing method is used in a terminal and includes the following steps.

[0061] In step S11 , in response to a photographing instruction, a plurality of first images with different preset magnifications are generated to be displayed.

[0062] The photographing instruction is used to trigger the terminal to perform a photographing operation, thereby generating a plurality of first images with different preset magnifications to be displayed.

[0063] The preset zoom ratio is a parameter used to describe the zoom range of a camera, indicating the zoom ratio of the camera from short focal length to long focal length. For example, if the zoom range of a camera is from 24mm to 120mm, then the preset ratio is 1x to 5x. The camera can provide a zoom capability of 1x to 5x, and the first images of different preset ratios are collected by cameras of different focal lengths.

[0064] See also Figure 2As shown, different preset magnifications correspond to different focal lengths and fields of view (FOV). The smaller the preset magnification, the smaller the focal length and the larger the field of view; conversely, the larger the preset magnification, the larger the focal length and the smaller the field of view. For example, the first preset magnification of 0.6 corresponds to a focal length of 14mm and a field of view of 90°, and the captured image can only show the straight path; the second preset magnification of 1 corresponds to a focal length of 28mm and a field of view of 53°, and the captured image can not only show the straight path, but also the curved path at the end of the path; the third preset magnification of 2 corresponds to a focal length of 50mm and a field of view of 31°, which can show houses in the distance; the fourth preset magnification corresponds to a focal length of 200mm and a field of view of 8°, which can show houses farther away. The longer the focal length, the larger the preset magnification, the smaller the field of view, and the farther the object that can be captured.

[0065] The field of view refers to the range that can be observed in the camera. Figure 2 As shown, the larger the field of view, the wider the range that the camera can capture, but the objects in the picture will appear smaller; conversely, the smaller the field of view, the smaller the range that can be captured, but the objects in the picture will appear larger.

[0066] The terminal can be equipped with several types of cameras, including the main camera, ultra-wide-angle lens, zoom lens and macro lens. The main camera is the core camera for most photo and video shooting. It has high pixels and optical performance, and can provide clear and delicate images. The ultra-wide-angle camera has a wider field of view and is used to shoot wide scenes, such as landscapes, buildings or group photos, and can capture the details of the picture with a larger field of view. The zoom lens has optical zoom capability and can achieve long-distance shooting, allowing the photographer to zoom in and out without moving the position, and can shoot distant objects or details. The macro lens is used to shoot small objects at a close distance, such as flowers, insects, etc. It has a short focus distance and high magnification, and can capture the details of tiny objects.

[0067] In the disclosed embodiment, the plurality of first images with different preset magnifications are acquired by capturing with cameras with different focal lengths, and / or are acquired by cropping after being photographed by the camera.

[0068] When a photo-taking instruction is obtained, different types of cameras on the terminal can be controlled to shoot the first image with focal lengths and fields of view corresponding to different preset magnifications, thereby generating first images with different preset magnifications. For example, the ultra-wide-angle camera on the terminal can be controlled to shoot a first image with a magnification of 0.6 with a focal length and field of view corresponding to 0.6; the main camera on the terminal can be controlled to shoot a first image with a magnification of 1 with a focal length and field of view corresponding to 1, and the zoom lens on the terminal can be controlled to shoot a first image with a focal length and field of view corresponding to 2, thereby generating first images with three preset magnifications of 0.6, 1 and 2. It can be understood that, in response to the photo-taking instruction, the terminal can simultaneously control cameras with different focal lengths, such as the main camera, the ultra-wide-angle camera and the zoom lens, to shoot, so as to obtain first images with different preset magnifications.

[0069] For another example, after the first image is acquired by a camera with a fixed focal length (such as an ultra-wide-angle camera), the first image with a magnification of 0.6 can be cropped to a first image with a magnification of 0.8.

[0070] In step S12, a plurality of first images with different preset magnifications are displayed.

[0071] After acquiring the first images of different preset magnifications of the terminal, the first images of different preset magnifications can be displayed in the photo album of the terminal, and the user can select at least one of the first images to keep according to his / her own needs.

[0072] In the related art, when the user does not adjust the image magnification to shoot a distant object, the user can magnify the distant object in the image by cropping. Figure 4 As shown, the image taken by the user shows a scene of "people dancing on the stage with many audiences under the stage". When the user wants to show only the people dancing on the stage in the image, the image can be cropped to remove the audience from the image and retain the image of the people dancing on the stage. However, the clarity of the image of the people dancing on the stage obtained after cropping will decrease and the image will be blurry.

[0073] In the present disclosure, images are captured simultaneously with different focal lengths, so that first images with different preset magnifications can be generated. For example, when a user triggers a photo button, 0.6x, 1x, and 2x images of "people dancing on the stage with many audiences under the stage" will be captured simultaneously through multiple types of cameras. The 2x image can clearly show the person dancing on the stage. The 2x image not only meets the user's need to shoot distant objects, but also retains image clarity, so the user can keep the 2x image.

[0074] It can be understood that the reason why the present disclosure can display a first image with a large preset magnification of 2 times while retaining image clarity compared to the related art is that the present disclosure uses a zoom lens type camera to shoot a first image with a larger preset magnification. The zoom lens has a larger focal length, so it can clearly capture distant objects.

[0075] Through the above technical solution, when taking photos, the user can directly trigger the photo button, and the terminal can respond to the photo instruction and display multiple first images with different preset magnifications.

[0076] During this process, on the one hand, the user does not need to adjust the image magnification during shooting, and multiple first images with different preset magnifications can be displayed, thereby preventing the user from missing the shooting moment they want to shoot; on the other hand, since among the multiple first images with different preset magnifications displayed, there are images with the magnification required by the user, the user can retain the images he or she needs, thereby improving the user experience.

[0077] The optional embodiments and specific embodiments involved in the above steps S11 to S12 are introduced below.

[0078] Figure 3 A schematic diagram of generating multiple first images with different preset magnifications is shown. Generating multiple first images with different preset magnifications includes: generating multiple first images with different preset magnifications in response to a photo taking instruction when the preview screen is stable when the terminal takes photos.

[0079] The stabilization of the preview image includes at least one of the following: the exposure value of the preview image reaches a first convergence condition, the white balance of the preview image reaches a second convergence condition, and the focus of the preview image reaches a third convergence condition.

[0080] See also Figure 5 As shown, the preview screen refers to when the terminal's camera is turned on and ready to shoot, the terminal screen will display the real-time picture captured by the camera, so that the user can see the preview screen and adjust the shooting angle and shooting parameters, and then shoot the picture they need.

[0081] 3A convergence is understood when the exposure value of the preview image reaches the first convergence condition, the white balance of the preview image reaches the second convergence condition, and the focus of the preview image reaches the third convergence condition.

[0082] Exposure is the brightness level in an image. Appropriate exposure can make an image look bright and detailed. Overexposure will make the image too bright, and underexposure will make the image dark. The terminal is equipped with an automatic exposure function. The camera can automatically adjust parameters such as shutter speed, aperture size and sensitivity according to the ambient light to obtain the appropriate exposure value. When the exposure value reaches the first convergence condition, it means that the image in the preview screen is neither too bright nor too dark.

[0083] White balance is to adjust the color temperature in the image so that the white area looks real and has no color deviation. Different light sources such as daylight, incandescent lamps and fluorescent lamps will produce different color temperatures. The terminal is equipped with an automatic white balance function. The camera can automatically monitor the color temperature of the ambient light and adjust the color information of the image accordingly to make the presented color closer to the real environment.

[0084] Focusing is the process of ensuring a clear image. The terminal is equipped with an autofocus function. When the autofocus function is turned on, the terminal will analyze the clarity and distance of the target object and automatically adjust the focal length of the camera to keep the target object in clear focus. When the focus reaches the third convergence condition, it means that the image in the preview screen is clear enough.

[0085] When the user triggers the camera to start and enters the 3A convergence process, when the picture content in the preview screen of the terminal is stable, it means that cameras with different focal lengths and fields of view are ready. At this time, in response to the photo command triggered by the user, multiple cameras with different focal lengths and fields of view can be used to simultaneously capture the first images with different preset magnifications.

[0086] Through the above technical solution, the terminal responds to the photo command only when the preview picture of the photo is stable, so that the exposure value, white balance and focus of the first image taken can be automatically adjusted to appropriate values, so that the quality of the presented first image is better.

[0087] Figure 6 A schematic diagram of displaying a first image with a magnification ratio greater than single magnification is shown, and displaying the first image with a magnification ratio greater than single magnification includes: in response to a focusing operation on a target object displayed in a preview screen of a terminal, displaying the target object in the first image.

[0088] The single magnification refers to a preset magnification of 1 times, and the first image with a magnification greater than the single magnification refers to a first image with a preset magnification greater than 1 times, such as 1.5 times, 1.7 times, 2 times, etc.

[0089] The focusing operation may be a touch operation of the user on the target object in the preview image, or may be a focusing operation of the terminal automatically focusing on the target object.

[0090] See also Figure 2As shown in the figure, when the preset magnification increases, the focal length increases and the field of view decreases accordingly. Therefore, due to the reduction in the field of view, some objects cannot be displayed in the image, such as Figure 2 The image on the far right can only show the houses in the distance, but cannot show the path close to the terminal. At this time, the terminal can determine the target object that the user wants to lock based on the focus area touched by the user on the preview screen of the terminal, and display the locked target object when displaying the first image with a preset magnification.

[0091] For example, see Figure 6 As shown in FIG. 1 , in the scene of “people dancing on the stage and there are many audiences under the stage”, if the user wants to focus on shooting the scene of “people dancing on the stage”, the user will click “dancing people” on the preview screen of the terminal screen, thereby focusing the camera on “dancing people” ( Figure 6 The dotted box in the figure is the focus area), then the terminal can lock the target object that the user wants to lock as the "dancing person". Then when the 2x image is displayed, the "dancing person" locked by the user will be displayed in the 2x image, while the "audience under the stage" will not be displayed in the 2x image.

[0092] For another example, in the scenario of "people dancing on the stage and there are many audiences under the stage", if the user does not click on "the dancing people" and the terminal automatically focuses on the "dancing people", the first image of the "dancing people" can also be directly displayed in the 2x image, while the "audience under the stage" will not be displayed in the 2x image.

[0093] Through the above technical solution, when a first image with a magnification greater than single magnification is generated, the target object triggered by the user or automatically triggered by the terminal can be automatically displayed in the first image, so that the target object in the displayed first image is what the user wants to see, thereby improving the user experience.

[0094] Figure 7 and Figure 8 A schematic diagram showing a plurality of first images with different preset magnifications is shown, see Figure 7 and Figure 8 As shown, displaying multiple first images with different preset magnifications includes the following two methods:

[0095] Mode 1: Displaying a plurality of the first images with different preset magnifications on the same display page at the same time.

[0096] See also Figure 7 As shown, when the user clicks the shooting button to trigger the photo command, the terminal generates multiple first images with different preset magnifications. If the user clicks Figure 7The album button shown can simultaneously display multiple first images with different preset magnifications on one page, so that the user can directly keep the first images he needs on the page and delete the other unnecessary first images.

[0097] It can be understood that, in response to the confirmation operation of retaining the target image from the plurality of first images, the target image is retained and / or the first images other than the target image are deleted.

[0098] For example, the terminal displays the first images with preset magnifications of 0.6, 1, and 2, and when the user confirms to keep the 2-fold image, in order to avoid the user from making additional operations, the terminal can actively delete the first images with magnifications of 0.6 and 1. Of course, the terminal may not help the user delete the first images other than the target image, and the present disclosure does not limit this.

[0099] Mode 2: Displaying a plurality of the first images with different preset magnifications on different display pages.

[0100] See also Figure 8 As shown, when the user clicks the shooting button to trigger the photo command, the terminal generates multiple first images with different preset magnifications. If the user clicks Figure 8 The album button shown can display a first image of a preset magnification on the terminal screen. If the user needs to view other first images of preset magnifications, the user can slide the image left or right to view the first images of other magnifications.

[0101] For example, if a user clicks Figure 8 After clicking the album button shown, a first image with a preset magnification of 0.6 times will pop up on the terminal screen. If the user wants to view the first image with a preset magnification of 1 times, the user can slide the first image to the left, so that the first image with a preset magnification of 1 times will be displayed on the terminal screen.

[0102] Through the above technical solution, when multiple first images with different preset magnifications are displayed on the same page, it is convenient for users to perform the retention and deletion operations of the first image on the same page without having to slide the page to delete the first image; when multiple first images with different preset magnifications are displayed on different pages, it is convenient for users to view the details of the first images with different preset magnifications on different pages, thereby facilitating users to decide which first images with preset magnifications should be deleted.

[0103] Figure 7 and Figure 8 A method for displaying multiple first images with different preset magnifications is shown. Displaying multiple first images with different preset magnifications includes: cropping at least one first image among the multiple first images with different preset magnifications to obtain a second image with a target magnification; and displaying the second image and the multiple first images with different magnifications.

[0104] The target magnification of the cropped second image is greater than the preset magnification of the first image before cropping, and the difference between the target magnification and the preset magnification is less than a preset value, which may be 0.3.

[0105] For example, the terminal generates a first image at 0.6 times, 1 times, and 2 times. When cropping, the 0.6 times first image can be cropped into a 0.8 times second image, the 1 times first image can be cropped into a 1.2 times second image, and the 2 times first image can be cropped into a 2.2 times second image. When displaying, the 0.6 times, 0.8 times, 1 times, 1.2 times, 2 times, and 2.2 times images can all be displayed.

[0106] Through the above technical solution, multiple first images with different preset magnifications can be cropped to obtain a second image with a target magnification. On the one hand, more images with preset magnifications can be provided for users to choose from, so that users can select images with magnifications they need; on the other hand, when cropping, the target magnification obtained by cropping is slightly larger than the preset magnification of the first image before cropping, so the clarity of the obtained second image will not be greatly affected.

[0107] Figure 3 A schematic diagram of generating a plurality of first images with different preset magnifications is shown, and generating a plurality of first images with different magnifications includes the following steps:

[0108] In step S21, in response to the photographing instruction, the captured real-time images of different preset magnifications are loaded into different buffers.

[0109] Different buffers are used to temporarily store real-time images with different preset magnifications, and the same buffer is used to temporarily store real-time images with the same preset magnification.

[0110] For example, the first buffer is used to temporarily store real-time images with a preset magnification of 0.6 times; the second buffer is used to temporarily store real-time images with a preset magnification of 1 times; and the third buffer is used to temporarily store real-time images with a preset magnification of 2 times.

[0111] There are multiple real-time images of the same preset magnification loaded in the same buffer, so the multiple real-time images of the same preset magnification loaded in the same buffer can be spliced, smoothed, cropped, etc., so that the first image of the preset magnification displayed is obtained by processing multiple real-time images.

[0112] Loading into different buffers includes: in response to the photographing instruction, using cameras with different focal lengths to shoot the real-time images with different preset magnifications; and loading the real-time images with different preset magnifications into different buffers.

[0113] The preset magnifications of the real-time images captured by cameras with different focal lengths are different, so the real-time images with different preset magnifications captured by cameras with different focal lengths can be loaded into different buffers.

[0114] In step S22, the real-time images in the different buffers are processed to obtain first images with different preset magnifications.

[0115] Multiple real-time images output from the same buffer are stitched, smoothed, cropped, etc. to obtain a first image with the same preset magnification.

[0116] Through the above technical solution, by using different buffers to temporarily store real-time images with different preset magnifications, when performing image processing, the buffer can be used as a division unit, and multiple real-time images output by one buffer can be centrally processed, while multiple real-time images output by another buffer can be centrally processed, so that the processes of processing multiple first images with different preset magnifications are independent of each other, thereby avoiding mutual influence between the processing processes of multiple real-time images with different preset magnifications.

[0117] Figure 5 and Fig. 9 The following two methods are shown:

[0118] Mode 1: In response to a triggering operation on a preset button on the terminal, the photographing instruction is generated; in response to the photographing instruction, a plurality of first images with different preset magnifications are generated, and the preset button is a virtual button.

[0119] See also Figure 5 As shown, Figure 5 The center of the terminal screen is a preview screen, the left side is an album button, the middle is a virtual button, that is, a virtual photo button, and the right side is a flip button for flipping the camera; when the user touches the virtual button, the terminal can generate a photo instruction in response to the user's triggering operation of the virtual button, and generate multiple first images with different preset magnifications for the user.

[0120] Mode 2: In response to a triggering operation on a preset button on the terminal, the photographing instruction is generated; in response to the photographing instruction, a plurality of first images with different preset magnifications are generated, and the preset button is a physical button.

[0121] See also Fig. 9 As shown, the volume +, volume - and power buttons are arranged from top to bottom on the right side of the terminal. The physical button can be any one of the volume +, volume - and power buttons. When the user long presses the volume - or double-clicks the power button, the terminal can generate a photo-taking instruction in response to the user's triggering operation of the physical button, and generate multiple first images with different preset magnifications for the user.

[0122] Of course, the above-mentioned setting of the volume +, volume - and power button is only an example. The volume - and power button can be set according to actual needs in an actual terminal, and the present disclosure does not limit this.

[0123] Through the above technical solution, the user can quickly trigger a photo-taking command by touching a virtual button or pressing a physical button, thereby generating a plurality of first images with different preset magnifications for the user.
