In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

Some of the nouns or terms referred to in the claims and the specification of the present application will be explained first.

The expression bag: is a Chinese vocabulary and is a mode for expressing emotion by adopting pictures. The expression package comprises a dynamic expression package and a static expression package; specifically, a dynamic emoticon can be generated by using a plurality of images including different contents, and a static emoticon can be generated by using a static image (for example, one image).

The method for generating an expression package according to the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

The method for generating the expression package can be applied to a scene of generating the user-defined expression package.

For example, when a user needs to generate a custom expression package, the user may perform input on a first control on an interface where the user wants to make the expression package, so as to trigger an expression package generation device to acquire M screen capture images of a current display interface of the electronic device, determine a dynamic region (for example, a first region in the embodiment of the present application) according to the multiple images, and then generate a target expression package corresponding to N target images according to N target images corresponding to the region, so that the custom expression package may be obtained. Therefore, the expression package generating device can determine the dynamic area based on the input of the user, and generate the self-defined expression package based on the N target images corresponding to the dynamic area without installing an expression package generating tool, searching expression package materials and manually editing and processing the expression package materials in the expression package generating tool, so that the process of generating the self-defined expression package can be simplified, and the man-machine interaction performance is improved.

As shown in fig. 1, an embodiment of the present application provides an emoticon generation method, which may include steps 101 to 104 described below.

Step 101, an expression package generation device receives a first input of a user to a first control.

The first control can be used for triggering the expression package generating device to generate the expression package.

Optionally, in this embodiment of the application, when the user needs to customize the emoticon, the user may perform a first input on a first control in an interface on which the emoticon is required to be made, so as to trigger the emoticon generation device to generate the emoticon based on the content in the interface. The interface can be any possible interface such as a video playing interface, a chat interface, a shooting preview interface and the like, and can be determined according to actual use requirements, and the embodiment of the application is not limited.

Optionally, in this embodiment of the application, the first control may be displayed on the interface or may be hidden in the interface. When the first control is hidden, before the user executes the first control, the first control may be displayed on the interface by an input-triggered emoticon generating apparatus.

Optionally, in this embodiment of the application, the first input may be a touch input to the first control, for example, a click on the first control, a long-press input, and the like; or may be a voice input; the method can be determined according to actual use requirements, and the embodiment of the application is not limited.

And step 102, responding to the first input by the expression package generating device, and acquiring M screen capture images of the current display interface of the electronic equipment.

Wherein M may be a positive integer.

In the embodiment of the application, the expression package generating device can acquire M screen capture images of the current display interface of the electronic equipment in a screen capture mode of the electronic equipment.

Optionally, in this embodiment of the application, the M screen shots may be obtained by taking a screen of a whole interface region of the current display interface of the electronic device for M times, or may be obtained by taking a screen of a part of interface region of the current display interface of the electronic device for M times.

Alternatively, in this embodiment of the application, the M screen capture images may be images obtained by performing screen capture M times on the same area (hereinafter referred to as a target area) of the screen of the electronic device.

Optionally, in this embodiment of the application, the target area may be all screen areas of a screen of the electronic device; the target area may be an area where a certain interface in the screen of the electronic device is located, and may be determined specifically according to actual use requirements, which is not limited in the embodiment of the present application.

Optionally, in this embodiment of the application, the emoticon generating apparatus may capture a screen of a current display interface of the electronic device at a preset period, so as to obtain the M screen-captured images. For example, the emoticon generating means may screen-capture the current display interface of the electronic device once every 10 seconds.

Optionally, in this embodiment of the application, the M screen capturing images may be images obtained by capturing a screen of a current display interface of the electronic device within a first preset time period (which may be determined according to actual use requirements, and this embodiment of the application is not limited). For example, the first preset time duration may be 500ms, after the expression package generation device captures a screen once, it is first determined whether the screen capture time duration reaches the first preset time duration, if the screen capture time duration reaches the first preset time duration, the screen capture is ended, and all screen capture images obtained by screen capture are determined as the M screen capture images.

Optionally, in this embodiment of the application, the number of the M screen shots may also be preset, so that the emoticon generating apparatus may end the screen shot after the mth screen shot.

In the embodiment of the present application, the size (area and shape) of the M screen shots is the same, and the M screen shots are in the same coordinate system (hereinafter referred to as a target coordinate system), and the coordinate ranges of the M screen shots in the target coordinate system are the same.

And step 103, the expression package generating device determines a first area according to the M screen shots.

Wherein, the first area can be a content difference area between the M screen capture images.

In this embodiment of the application, the first area of the M screen shots includes at least one different content.

For example, fig. 2 is a schematic diagram of M screen shots and a first region. Assuming that M screen shots are an image M1, an image M2, and an image M3 arranged in this order of acquisition, and the first region is a region indicated by a dashed circle 20 in fig. 2, then, as shown in fig. 2, the content 21 is not included in the first region of the image M1, the content 21 is included in the first region of the image M2, and the content 21 is not included in the image M3. As such, at least one different content included in the first area of the M screen shots is the content 21.

Optionally, in this embodiment of the application, at least one content difference region may be included between M screen shots. The first area may specifically be one or more content difference areas in the at least one content difference area, and may specifically be determined according to actual usage requirements, which is not limited in this embodiment of the application.

For the description of at least one content difference region, detailed description will be made in the following embodiments, and details are not repeated herein to avoid repetition.

And 104, generating a target expression package corresponding to the N target images by the expression package generating device according to the N target images corresponding to the first area.

Wherein N may be a positive integer.

Optionally, in this embodiment of the application, after the expression package generating device determines the first area, the expression package generating device may cut, according to an area corresponding to the first area, N screen shots that are different from the M screen shots, to obtain the N target images (in a first manner). Or, the expression package generating device may directly crop N images of the M screen shots according to the first region to obtain the N target images, where N is less than or equal to M (the second mode).

In this embodiment of the application, after the expression package generation device obtains the N target images, each image in the N target images may be encoded according to a coding mode corresponding to a file format of a static expression package (or a dynamic expression package), and each encoded image is synthesized into the target expression package.

Optionally, in this embodiment of the application, if the expression package generation device encodes each image in the N target images according to the coding mode corresponding to the file format of the static expression package, the target expression package is the static expression package, and in this case, N may be greater than or equal to 1. If the expression package generating device encodes each image in the N target images according to the encoding mode corresponding to the file format of the dynamic expression package, the target expression package is a dynamic expression package, and in this case, N may be greater than 1.

Optionally, in this embodiment of the application, the file format of the static emoticon may include: any possible formats such as JPEG format jpg format, png format, tif format, and the like can be determined according to actual use requirements, and the embodiment of the present application is not limited. The file format of the dynamic emoticon may include: GIF format, webp format, apn format and other optional formats.

For example, taking the target expression package as a dynamic expression package, the expression package generating device may encode each target image according to a GIF encoding mode corresponding to the GIF format, and synthesize N encoded target images to obtain the target expression package.

Optionally, in this embodiment of the application, after the emotion packet generation device synthesizes the target emotion packet, the target emotion packet may be stored in the electronic device, or the target emotion packet may be stored in a favorite, and the target emotion packet may also be sent to other electronic devices. The method can be determined according to actual use requirements, and the embodiment of the application is not limited.

In the method for generating the expression package provided by the embodiment of the application, the expression package generating device can determine the first region according to the acquired M screen capture images of the current display interface of the electronic device, and generate the target expression package (corresponding to the N target images) according to the N target images corresponding to the first region, without installing an expression package generating tool, searching for expression package materials, and manually editing and processing the expression package materials in the expression package generating tool, so that the process of generating the custom expression package can be simplified.

The following exemplarily describes a method of the emoticon generation apparatus determining the first area.

Optionally, in this embodiment of the application, the expression package generation device may specifically determine the first area by a pixel comparison method according to the M screen shots. The step 103 can be specifically realized by the steps 103a and 103b described below.

Step 103a, the expression package generating device performs pixel comparison on the ith screen capture image in the M screen capture images and the (i + 1) th screen capture image in the M screen capture images, determines a content difference area between the ith screen capture image and the (i + 1) th screen capture image, and obtains at least one content difference area.

The ith screen capture image and the (i + 1) th screen capture image can be screen capture images in the M screen capture images, and i can be an integer from 1 to M-1.

In the embodiment of the application, the ith screen capture image is a screen capture image obtained by capturing the screen for the ith time, and the ith screen capture image is a screen capture image obtained by capturing the screen for the ith time. Namely, the ith screen capture image and the (i + 1) th screen capture image are screen capture images obtained by two adjacent screen captures.

Exemplarily, the expression package generating device may extract pixel points of an i-th screenshot image and pixel points of an i + 1-th screenshot image, compare the pixel points of the i-th screenshot image and the pixel points of the i + 1-th screenshot image one by one in a row unit, and record, for each row of pixel points, when a difference is found between one pixel point (difference start pixel point), coordinate information (which is coordinate information in a target coordinate system) of a current pixel point and a current row number; when another pixel point of the line behind the one pixel point is the same, the coordinate information of the previous pixel point (difference ending pixel point) of the other pixel point in the line is recorded, and the area between the difference starting pixel point and the difference ending pixel point is a pixel difference area of the line. It can be understood that after the expression package generation device compares the last pixel point of the last line of the ith screenshot image with the last pixel point of the last line of the (i + 1) th screenshot image, the content difference region between the ith screenshot image and the (i + 1) th screenshot image can be determined according to the recorded pixel difference region of each line. It can be seen that, in the embodiment of the present application, the content difference region between the ith screenshot image and the (i + 1) th screenshot image is a region formed by different pixel points between the ith screenshot image and the (i + 1) th screenshot image.

It can be understood that a row of pixel points may include a plurality of pixel difference regions, or may not have a pixel difference region, and may be determined specifically according to actual use requirements.

Optionally, in this embodiment of the application, the comparing of the two pixel points by the emotion bag generation device may specifically be comparing gray values or RGB values of the two pixel points. The difference between one pixel point and another pixel point may be that the matching degree between the gray values or RGB values of the two pixel points is less than or equal to a preset threshold.

In this embodiment of the application, the at least one content difference area may be a sum of content difference areas between two adjacent screen capture images in the M screen capture images. In other words, at least one content difference region is the whole content difference region obtained after the images in the M screen capture images are compared pairwise.

Exemplarily, it is assumed that M screen shots sequentially follow the acquisition sequence: screenshot image 1, screenshot image 2, screenshot image 3 and screenshot image 4, then the at least one content difference region may include: a content difference region between the screenshot image 1 and the screenshot image 2, a content difference region between the screenshot image 2 and the screenshot image 3, a content difference region between the screenshot image 3 and the screenshot image 4, and a content difference region between the screenshot image 4 and the screenshot image 5.

Optionally, in this embodiment of the application, for each content difference area in the at least one content difference area, the expression package generation apparatus may record coordinate information of one content difference area in the target coordinate system, and record an area of the content difference area.

Optionally, in this embodiment of the application, an area of each content difference region in the at least one content difference region is greater than or equal to 5dp by 5 dp. Specifically, the expression package generation device may discard the content difference region with an area smaller than 5dp × 5dp, so as to reduce subsequent calculation amount and eliminate an error caused by cursor flicker or time variation.

Alternatively, in the embodiment of the present application, in order to facilitate calculation of the areas of the content difference regions, the emoticon generation apparatus may use, as each content difference region, a regular pattern (for example, a circle, a square, a rectangle, a triangle, or the like) that circumscribes the outer contour line of each content difference region. That is, in an actual implementation, for each of the at least one content difference region, an area of one content difference region may be greater than or equal to an actual area of the difference content, and a shape of one content difference region may be different from a shape of the difference content.

For example, fig. 3 is a schematic diagram of determining a content difference region between two adjacent screen shots. As shown in fig. 3 (a), the person image 31 and the tree image 32 are included in the 2 nd (i.e., i + 2) th screenshot image, and as shown in fig. 3 (b), the tree image 32 is included in the 3 rd (i.e., i +1 ═ 3) th screenshot image, and the position of the tree image 32 in the 3 rd screenshot image is the same as that of the tree image in the 2 nd screenshot image, then, as shown in fig. 3 (c), the emoticon generating means may determine a rectangular region 33 circumscribing the person image 32 as a content difference region between the 2 nd and 3 rd screenshot images.

Step 103b, the expression package generating device determines the content difference area meeting the preset condition in the at least one content difference area as the first area.

Optionally, in this embodiment of the application, the preset condition may be at least one of the following: (1) the content difference region with the largest occurrence number; (2) the content difference region with the largest area; (3) a content difference region selected by the user. That is, the preset condition may be any one of (1), (2), and (3), or any two of (1), (2), and (3), or (1), (2), and (3).

Optionally, in this embodiment of the application, when the preset condition includes (1) above, the expression package generation device may determine the number of times that each content difference area of the at least one content difference area appears, and determine the content difference area with the largest number of times that the content difference area appears in the at least one content difference area as the first area.

In this embodiment, the number of occurrences of one content difference region may be the number of occurrences of at least a part of the content difference region.

Example 1, as shown in fig. 4, assuming that at least one content difference region is 5 content difference regions, which are region a1, region a2, region A3, region a4, and region a5, respectively: since there is an intersection between region a1 and region a2 (the filled region as shown in fig. 4), the number of occurrences of region a1 and region a2 is 2 times each; and since the region A3 and the region a4 completely coincide, the number of occurrences of the region A3 and the region a4 is also 2 times each; region a5 does not coincide with any other region, so region a5 occurs 1 time. That is, it can be understood that the content difference regions with the largest occurrence number are respectively: region a1, region a2, region A3, and region a 4.

Optionally, in this embodiment of the application, when the preset condition includes (2) above, the expression package generation device determines, as the first area, a content difference area with a largest area in the at least one content difference area.

Optionally, in this embodiment of the application, when the preset condition includes the foregoing (3), the electronic device may display P identifiers, each identifier may indicate a position of one content difference region in the target coordinate system, and the user may specifically determine the first region by selecting an identifier in the P identifiers.

Optionally, in this embodiment of the application, the preset conditions are different, and the first areas determined according to the at least one content difference area may also be different.

Example 2, it is assumed that the areas of the region a1, the region a2, the region A3, the region a4, and the region a5 in the above example 1 are: s1, s2, s3, s4 and s5, and s1 > s2, s2 > s3, s3 > s4, s5 > s 1. Then, if the preset conditions are that the area is the largest and the number of occurrences is the largest, the expression package generation means may determine the area a1 as the first area; if the preset condition is that the area is the maximum, the expression package generation means may determine the area a5 as the first area.

It is understood that, in the embodiment of the present application, the first area is different, and the target emoticon may also be different.

When it needs to be described, in the embodiment of the present application, the expression package generation device in the above embodiment first acquires M screen capture images, and then determines a content difference area between an i-th screen capture image in the M screen capture images and an i + 1-th screen capture image in the M screen capture images, in an actual implementation, after acquiring the i-th screen capture image and the i + 1-th screen capture image, the expression package generation device may determine the content difference area between the two screen capture images; then acquiring the (i + 2) th screen capture image, and determining a content difference area between the (i + 1) th screen capture image and the (i + 2) th screen capture image; and in the same way, at least one content difference area can be obtained until the Mth screen capture image is obtained and the content difference area between the M-1 st screen capture image and the Mth screen capture image is determined.

In the embodiment of the application, different first areas can be determined according to different preset conditions, so that the flexibility and diversity of determining the first areas can be improved, and the flexibility and convenience of generating the custom expression packages can be improved.

In the embodiment of the application, at least one content difference area is obtained by the expression package generating device in a pixel comparison mode, so that the first area can be accurately determined.

The first and second embodiments will be described in detail below.

First mode

Optionally, in this embodiment of the application, in the first manner, the expression package generating device may first acquire N screen capture images (i.e., the N second images), then crop an image of a second region corresponding to the first region in the N screen capture images, and determine the N acquired images as N target images. And the acquisition time of the N screen capture images is different from that of the M screen capture images. Specifically, the N screen capture images may be acquired after the M screen capture images are acquired, and may also be acquired after the first region is determined, which may be determined specifically according to actual use requirements, and the embodiment of the present application is not limited.

For example, in the embodiment of the present application, before the step 104, the method for generating an emoticon provided in the embodiment of the present application may further include the following steps 105 to 107.

And step 105, responding to the first input by the expression package generating device, and acquiring N screen capture images of the current display interface of the electronic equipment.

Optionally, in this embodiment of the application, the content of the N screenshot images and the content of the M screenshot images of the current display interface of the electronic device, which are obtained by the emotion package generation apparatus, may correspond to the same content or may correspond to different contents. The method can be determined according to actual use requirements, and the embodiment of the application is not limited.

For example, assuming that the content a and the content b are displayed on the screen of the electronic device in a circulating manner, the content a and the content b may be included in the N screenshot images acquired by the expression package generation device, and the content a and the content b may also be included in the M screenshot images, so that the content of the N screenshot images acquired by the expression package generation device corresponds to the same content as the content of the M screenshot images.

For another example, if content a, content b, content c, and content d are sequentially displayed on the screen of the electronic device, and the content a, the content b, the content c, and the content d are different, then if the M screenshot images acquired by the emotion package generation apparatus include the content a and the content b, and the N screenshot images acquired by the emotion package generation apparatus include the content c and the content d, the content of the N screenshot images corresponds to different content from the content of the M screenshot images.

And 106, determining a second area corresponding to the first area in the N screen capture images by the expression package generating device.

In the embodiment of the application, the N screen shots and the M screen shots are both in the target coordinate system, and the coordinate information of the second area in the target coordinate system is the same as the coordinate information of the first area in the target coordinate system.

And step 107, the expression package generating device cuts the image of the second area in the N screen capture images to obtain N target images.

In this embodiment of the application, for each target image in the N target images, the expression package generation device may crop an image of the second area in one target image to obtain one target image. In this way, after the expression package generation device cuts the image of the second area in the N screen shots, N target images can be obtained.

It is understood that the expression package generation device may specifically cut the image of the second area in one target image by reserving the image of the first area in the target image and discarding the images except the first area in the target image.

Optionally, in this embodiment of the application, the number of the N screen shots may be preset or determined by an input of a user (for example, a second input described below), where when the N screen shots are determined by the input of the user, the expression package generating device may acquire the N screen shots after acquiring the M screen shots.

In the embodiment of the application, the user does not need to manually search the emotion bag material and cut the emotion bag material, so that the process of generating the user-defined emotion bag can be further simplified, and the man-machine interaction performance is improved.

Second mode

Optionally, in this embodiment of the application, in a second implementation manner, after the step 103 and before the step 104, the method for generating an expression package provided by this embodiment of the application may further include the following step 108.

And step 108, the expression package generating device responds to the first input, and N images in the M screen capture images are cut to obtain N target images.

Wherein N is less than or equal to M.

Optionally, in this embodiment of the application, the N images may be any N images in the M screen capture images, and may be determined specifically according to actual use requirements, and this embodiment of the application is not limited.

For the description of step 108, reference may be made to the related description in step 107, and details are not repeated here to avoid repetition.

Optionally, in this embodiment of the application, the M screen shots in step 108 may be original images of the M screen shots in step 102, or may be M backup screen shots obtained by the expression package generation device backing up the M screen shots in step 102. The method can be determined according to actual use requirements, and the embodiment of the application is not limited.

In the embodiment of the application, on one hand, the M screen capture images can be used for determining the first area and can be used as the emoticon materials for generating the emoticon, so that an emoticon generating device is not needed to capture the current display interface of the electronic equipment, that is, the emoticon materials are not needed to be specially acquired, the time consumed for acquiring the emoticon materials can be saved, and the speed for generating the custom emoticon can be increased; on the other hand, the N target images are the images of the first areas of the N images of the M screen capture images, so that the N target images can be ensured to comprise at least one different content, and the target expression package can be ensured to have a better display effect when the dynamic expression package is generated by adopting the N target images.

Optionally, in this embodiment of the application, in the first manner, when the N screen shots are determined for the user input, after the first input of the user is received by the emotion bag generation apparatus, a second control may be further displayed (for example, the second control may be an "end control"), and the second control may be configured to trigger the emotion bag generation apparatus to end acquiring emotion bag materials, and process the acquired emotion bag materials to obtain a custom emotion bag (for example, the target emotion bag).
