Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
An image cropping method and apparatus of an embodiment of the present application are described below with reference to the drawings.
The execution main body of the image cropping method in the embodiment of the application can be a device with an image processor, such as a mobile phone, a tablet computer, a personal digital assistant and a wearable device, and the wearable device can be an intelligent bracelet, an intelligent watch and intelligent glasses.
Fig. 1 is a flowchart of an image cropping method according to an embodiment of the present application, as shown in fig. 1, the method comprising:
The first image to be processed may be an independent image in a single album or multiple albums, etc., or may be a certain frame or multiple frames of images in a video, and when multiple frames of images in the video are processed, the video may be generated according to the processed images, so as to meet the related requirements in the scene. Such as video-based dynamic wallpaper settings, etc.
It should be noted that, in different application scenarios, the manner of obtaining the video character adding request is different, and the following example is illustrated:
the first example:
in this example, the user sends the image cropping request in a voice manner.
Specifically, after the user selects the first image, the sound pickup device collects the voice data of the user, and when a keyword such as "image cropping" is recognized in the collected voice data of the user, an image cropping request for the selected first image is acquired.
The second example is:
in this example, the user sends the image cropping request in the form of an action.
Specifically, after a first image is selected by a user, a gesture action or a facial expression action of the user is acquired through a camera, a touch screen or the like, the acquired action is matched with a preset action, and if the matching is successful, an image cutting request of the user for the first image is acquired.
Of course, in this example, the manner in which the user selects the first image may also be determined according to the motion, and is not described here again.
In this example, as shown in fig. 2, a selection control, a cropping menu, and the like are provided on the image interface, and the user may trigger the selection control of the first image to select the first image, and further, the sending of the image cropping request is realized by triggering the cropping menu.
In particular, considering that in some application scenarios, when a user edits a first image, there is a need to crop the image, for example, the user only wants to keep a part of the character image in the image, etc., in order to meet the personalized needs of the user, in one embodiment of the present application, a region is divided in a preset canvas to clip a picture by distribution of regions, and particularly, in the present embodiment, the preset canvas includes a first region and a second region, wherein, the number of the first area and the second area can be set arbitrarily, the first area is a transparent area, the second area is a non-transparent area, and the display priority of the second area is higher than that of the first area, that is, and after the image is moved from the first area to the second area, displaying a non-transparent picture of the second area instead of displaying a corresponding picture, and displaying the first image in the first area of the preset canvas.
And 104, when the image generation instruction is acquired, generating a second image according to a picture in a target area, wherein the target area is a partial area which is not covered by the second area in the first area.
Specifically, when the acquisition instruction is acquired, the distribution mode of the first area and the second area in the preset canvas is adjusted according to the cutting area in the cutting instruction, that is, the area outside the cutting area in the first area is covered by the second area, and the picture in the second area is not displayed any more, so that the cutting operation of the related picture is realized.
Of course, in this embodiment, in order to more intuitively show the cut-out area to the user, the transparency of the second area may be adjusted to be within the preset range, so that the second area is a semi-transparent area, as shown in fig. 3, in the second area, the user may see a specific cut-out image, which is convenient for the user to further adjust the cut-out area.
The triggering mode of the cutting instruction can be implemented through a touch screen action track or through a selection operation of transferring a cutting area selection tool. The cutting area may be an annular area, the first area is located in the ring of the second area, or the second area includes two sub-areas located on two sides of the first area, and the like.
In addition, in different application scenarios, the distribution modes of the first area and the second area in the preset canvas are adjusted to be different according to the clipping area in the clipping instruction, as a possible implementation mode, when the number and the distribution modes of the second area and the first area are as shown in fig. 3, the moving operation of the user on the image in the first area can be received, when the user moves the image in the first area left and right, the image can be clipped, and all the images shielded by the second area are equivalent to being clipped.
As another possible implementation manner, when the number and the distribution manner of the second areas and the first areas are as shown in fig. 4, the second areas can be covered in the images of the corresponding first areas through a drag operation on the second areas, and all the images blocked by the second areas are equivalent to being cropped.
As a further possible implementation manner, a cropping control and a cropping effect of the corresponding cropping control are displayed in a preset canvas, as shown in FIG. 5, an original image is displayed in a current canvas, the corresponding cropping control-375.0/667.0 and 375.0/812.0 three image sizes are displayed below the original image (with the size of 500.0/812.0), and when the original image is selected by a user to 375.0/812.0, the current image is covered by calling a white second area according to 375.0/812.0, so that the current image is displayed to 375.0/812.0 size, with continued reference to FIG. 5.
Further, after the image generation instruction is obtained, a second image may be generated from a screen in a target area, where the target area is a partial area of the first area that is not covered by the second area, and the target area further satisfies an image portion that a user wants to cut, where a trigger mode of the target area may be selected by the user based on a touch trajectory, or may be selected by invoking a selection tool, for example, the user inputs a touch trajectory along an outline of a person in the first area, and may select an area where the person is located as the target area. In addition, the image generation instruction may be triggered by voice, or may be triggered by clicking a corresponding image generation control, which is not described herein again.
As mentioned in the above embodiments, the image editing method in the present application can be used in video, and of course, can also be used in multiple images, thereby realizing personalized cropping of the image stream.
In an embodiment of the application, the cropping request includes a plurality of continuous first image sequences, the first image sequences may be derived from a plurality of images, or may be derived from continuous reading frames in a video, and the frames displayed in the target region are sequentially captured according to a first preset time interval, where the first preset time interval may be calibrated according to experimental data, and in order to ensure the integrity of captured frames, when the first image sequences are derived from the video, the first preset time interval may also be consistent with an original playing rate of the video.
However, when the screenshot is derived, the speed of storing the screenshot is usually slower than the screenshot speed, and if the screenshot speed is not slowed down, the cached screenshot pictures may be more and more, and finally, the memory may overflow.
Therefore, in an embodiment of the present application, the first image sequence may be further controlled to be played at a preset rate, where the preset rate is smaller than the original playing rate of the first image sequence, that is, when the edited picture is exported, the first image sequence is synchronously slowed down, for example, the preset rate is changed to one third of the original playing rate, thereby facilitating the screenshot operation of the displayed picture. And further, pictures displayed in the target area are intercepted according to a second preset time interval, wherein the second preset time interval is longer than the first preset time interval, the second preset time interval can be determined according to the storage speed, and every frame of picture is deleted in the cache, so that the memory overflow is avoided.
Further, specifically, according to the capturing order of each screen, the screens are sequentially subjected to synthesis processing, such as stitching processing, and a second image sequence after clipping is generated, where the playing time of each image in the second image sequence is a first preset time.
Of course, in order to further meet the personalized clipping requirement of the user, it may be further determined whether the generation instruction includes a clipping start time, if the clipping start time is included, the first image sequence is played from the start time, and is directly positioned to the image that the user wants to clip, and if the clipping start time is not included, the first image sequence is controlled to be displayed in the first area from the start image frame.
Therefore, the above embodiment implements clipping and editing of the images according to the visualization operation in the preset canvas, the synthesized second image sequence can be used for recording life fragments, dynamically publishing in social software, applying dynamic wallpaper, and the like, and the clipping operation does not depend on the learning and integration of codes any more.
To sum up, the image cropping method according to the embodiment of the application obtains an image cropping request, displays a first image in a first area of a preset canvas, where the preset canvas includes the first area and a second area, the first area is a transparent area, the second area is a non-transparent area, and a display priority of the second area is higher than a display priority of the first area, adjusts a distribution manner of the first area and the second area in the preset canvas according to the cropping area in the cropping instruction when the image cropping instruction is obtained, and finally generates a second image according to a picture in a target area when the image generating instruction is obtained, where the target area is a partial area in the first area that is not covered by the second area. Therefore, the image editing mode with low learning cost and high efficiency is realized, and the local editing requirement on the image is flexibly met by cutting the image.
