Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0025] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0026] The video generation circuit, method and electronic device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0027] The video generation circuit provided in the embodiment of the present application can be applied to the scenario of inserting files (such as images, texts, etc.) into the currently captured video.

[0028] For example, when a user needs to insert an image (such as an insert file in the embodiment of the present application) into the currently captured video, the original video captured by the camera can be obtained through the image processing chip, and the main control chip sends the original video to the display chip. The display chip can obtain the image that the user needs to insert, and the display chip can generate a target video based on the original video and the image, for example, inserting the image into the original video to generate the target video. The frame insertion processing by the independently set display chip can improve the efficiency of inserting files into the video, ensure the smoothness and real-time performance of the video picture, and reduce the power consumption of the main control chip.

[0029] Example 1

[0030] The embodiment of the present application provides a video generation circuit. Figure 1 A schematic diagram of the structure of a video generation circuit provided in an embodiment of the present application is shown. Figure 1 As shown, the video generation circuit may include: an image processing chip 11 , a main control chip 12 and a display chip 13 .

[0031] In an embodiment of the present application, the main control chip 12 is connected to the image processing chip 11 and the display chip 13 respectively; the image processing chip 11 is used to obtain the original video captured by the camera; the main control chip 12 is used to send the original video to the display chip 13; the display chip 13 is used to obtain the inserted file and generate the target video based on the original video and the inserted file.

[0032] It can be understood that in the embodiment of the present application, the image processing chip first obtains the original video captured by the camera (i.e., the video screen captured by the camera in real time), and then the image processing chip sends the obtained original video to the main control chip, so that the main control chip can send the original video to the display chip.

[0033] In the embodiment of the present application, the order in which the original video is received by the display chip and the display chip obtains the inserted file is not limited, that is, the display chip can obtain the inserted file after receiving the original file, or the display chip can first obtain the inserted file and then receive the original video.

[0034] Optionally, in an embodiment of the present application, the image processing chip can obtain the original video when the electronic device captures the original video through a camera.

[0035] In the embodiment of the present application, the display chip is a chip with frame insertion, noise reduction and picture effect processing functions; through the display chip, files can be inserted into the original video in real time (i.e., frame insertion), and the smoothness of video playback is guaranteed to avoid freezes.

[0036] Optionally, in the embodiment of the present application, the inserted file may be at least one of the following: an image, text, video / video clip, symbol, document, etc., which may be determined according to actual needs and is not limited in the embodiment of the present application.

[0037] Optionally, in the embodiment of the present application, the number of inserted files can be one or more, which can be determined according to actual needs and is not limited in the embodiment of the present application.

[0038] Optionally, in an embodiment of the present application, when the inserted file is an image, the image may be a user-defined image, or may be a default image of the electronic device, which may be determined based on actual needs and is not limited in the embodiment of the present application.

[0039] Optionally, in the embodiment of the present application, when the image is a user-defined image, the image may be an image manually drawn by the user, an image downloaded by the electronic device from the network, or an image stored in the electronic device.

[0040] Optionally, in an embodiment of the present application, in a possible implementation method, the display chip can be specifically used to: insert the insert file between the Nth video frame and the N+1th video frame of the original video to generate a target video, where N can be a positive integer.

[0041] Optionally, in the embodiment of the present application, N may be a user-defined value, or may be a system default value, which may be determined based on actual usage requirements and is not limited in the embodiment of the present application.

[0042] In the embodiment of the present application, since the display chip can insert the inserted file in the form of a separate video clip / video frame between any two video frames of the original video to generate a target video, it can not only improve the flexibility of the electronic device in inserting files into the video, but also retain all the elements of each video frame in the original video.

[0043] Optionally, in an embodiment of the present application, in another possible implementation method, the display chip can be specifically used to: fuse the inserted file with at least one video frame of the original video to obtain at least one fused image; and generate a target video based on the at least one fused image and the video frames in the original video that have not been fused.

[0044] Optionally, in an embodiment of the present application, each video frame in the at least one video frame corresponds to a fused image, and different video frames correspond to different fused images.

[0045] In an embodiment of the present application, for each video frame in at least one video frame, the display chip can fuse one video frame with the inserted file to obtain a fused image. After the display chip fuses at least one video frame with the inserted file respectively, the above-mentioned at least one fused image can be obtained.

[0046] It can be understood that in an embodiment of the present application, the display chip generates a target video based on the above-mentioned at least one fused image and the video frames in the original video that have not been fused, including: the display chip is used to replace the above-mentioned at least one video frame in the original video with the at least one fused image to generate the target video.

[0047] For example, suppose that the display chip fuses pattern 1 (i.e., the inserted file) with the second video frame in the original video (i.e., the at least one video frame mentioned above) to obtain a fused image, and then replaces the second video frame in the original video with the fused image to generate a target video, i.e., the frame number of the fused image in the target video is the same as the frame number 2 of the second frame image in the original video.

[0048] In the embodiment of the present application, since the display chip can first fuse the inserted file with at least one video of the original video to obtain at least one fused image, and then generate a target video based on the at least one fused image and the video frames in the original video that have not been fused, compared to the original video, at least some of the video frames in the target video include newly added elements (such as the inserted file), which not only improves the flexibility of the electronic device in inserting files into the original video, but also maintains the continuity of the video images taken by the camera on the basis of enriching the elements of at least some of the video frames in the original video.

[0049] In the video generation circuit provided in the embodiment of the present application, the inserted file is obtained through the display chip, and the target video is generated based on the original video and the inserted file. The frame insertion processing is performed by an independently set display chip, which can improve the efficiency of inserting files in the video, ensure the smoothness and real-time performance of the video picture, and reduce the power consumption of the main control chip.

[0050] Example 2

[0051] The present application embodiment provides a video generation method. Figure 2 FIG. 1 is a flow chart of a video generation method provided in an embodiment of the present application. The video generation method can be applied to the video generation circuit in the above-mentioned embodiment 1. Figure 2 As shown, the video generation method provided in the embodiment of the present application may include the following steps 201 and 202. The following is an example of an electronic device including the video generation circuit in the above embodiment 1 executing the method.

[0052] Step 201: The electronic device receives a first input from a user when the first screen area displays an original video and the second screen area displays an inserted file.

[0053] In the embodiment of the present application, the original video may be the video currently captured by a camera in the electronic device.

[0054] Optionally, in an embodiment of the present application, the video frame currently displayed in the first screen area may be a video frame captured most recently in the original video.

[0055] Optionally, in an embodiment of the present application, during the process of shooting a video, the electronic device may display a shooting interface (i.e., the original video) and display the video frames captured by the camera in the shooting interface. If the user needs to change the captured video screen, the user may trigger the electronic device to open the fun drawing board function through an input (hereinafter referred to as the target input), so that the electronic device may display the original video in the first screen area and the drawing board interface in the second screen area; wherein the drawing board interface may be used to display / draw the above-mentioned inserted file.

[0056] Optionally, in an embodiment of the present application, after the electronic device displays a sketchboard interface based on the target input, the sketchboard interface may be a blank interface, that is, no files are displayed in the sketchboard interface; or, the sketchboard interface may include files retained when the user last used the sketchboard interface, for example, a file most recently drawn by the user on the sketchboard interface or a file most recently loaded by the electronic device through the sketchboard interface. The specific details can be determined based on actual usage requirements and are not limited in the embodiments of the present application.

[0057] Optionally, in an embodiment of the present application, the above-mentioned inserted file can be: a file manually drawn by the user in the drawing board interface, a file loaded by the electronic device through the drawing board interface, or a file retained when the user last used the drawing board interface. The specific file can be determined based on actual usage requirements and is not limited in the embodiment of the present application.

[0058] Optionally, in an embodiment of the present application, the first screen area and the second screen area can be different areas of the same display screen in the electronic device, or can be areas in different display screens in the electronic device. The specific area can be determined based on actual usage requirements and is not limited in the embodiment of the present application.

[0059] Optionally, in the embodiment of the present application, the first input may be a touch input, a floating input, a preset gesture input, or a voice input, etc., which may be determined according to actual usage requirements and is not limited in the embodiment of the present application.

[0060] For example, the first input is a drag input in which the user drags the insert file from the second screen area to the first screen area.

[0061] Step 202: In response to a first input, the electronic device generates a target video based on an original video and an inserted file through a display chip.

[0062] Optionally, in an embodiment of the present application, the display chip generates a target video based on the original video and the inserted file, which can be any one of the following methods 1 to 3: Implementation method 1, the display chip inserts the inserted file between any two video frames of the original video to generate the target video; Implementation method 2, the display chip fuses the inserted file with at least one video frame in the original video to obtain at least one fused image, and replaces the at least one video frame in the original video with the at least one fused image frame to generate the target video; Implementation method 3, the display chip replaces at least one video frame in the original video with the inserted file to generate the target video.

[0063] Optionally, in an embodiment of the present application, in the above implementation mode 1, the above step 202 can be specifically implemented by the following step 202a.

[0064] Step 202a: In response to the first input, the electronic device inserts the insert file between the Nth video frame and the N+1th video frame of the original video through the display chip to generate a target video.

[0065] The Nth video frame may be determined based on user input, for example, the Mth video frame after the first input may be the Nth video frame, or may be a system default, and N may be a positive integer.

[0066] Optionally, in an embodiment of the present application, when the inserted file is an image, the display chip can process the image parameters of the image to obtain a target image, wherein the image parameters of the target image can match the image parameters of the video frame in the original video (the two are the same, or the matching degree of the two is greater than or equal to a first preset matching degree).

[0067] Optionally, in the embodiment of the present application, the image parameters may include at least one of the size and resolution of the image. It should be noted that in actual implementation, there may be a certain error between the processed image parameters and the image parameters of the video frame in the original video.

[0068] Optionally, in the embodiment of the present application, when the Nth video frame is determined based on user input, the second input and the first input for determining the Nth video frame may be two different inputs.

[0069] Optionally, in the embodiment of the present application, when the Nth video frame can be determined based on user input, the display chip can determine the Nth video frame in the following two ways (way 1 and way 2).

[0070] Method 1

[0071] Optionally, in the embodiment of the present application, the user can input a value N in the drawing board interface through the second input, and then the display chip can determine the video frame with the frame number N in the original video as the Nth video frame, and insert the insertion file between the Nth video frame and the N+1th video frame.

[0072] For example, assuming that the user inputs the number 6 in the drawing board interface through the second input, the display chip can insert the insert file between the 6th video frame and the 7th video frame in the original video.

[0073] Method 2

[0074] Optionally, in an embodiment of the present application, the display chip can determine the Nth video frame based on the frame number K of the video frame displayed in the first screen area when the electronic device receives the first input and the numerical value H corresponding to the second input, where K can be a positive integer and H can be an integer.

[0075] Specifically, assuming that when the electronic device receives the first input, the first screen area displays the Kth video frame of the original video, and the value corresponding to the second input is H, that is, the user enters the value H in the drawing board interface; then N=K+H.

[0076] When H is greater than 0, the display chip can insert the above-mentioned insertion file after the Hth video frame located after the Kth video frame; when H is less than 0, the display chip can insert the above-mentioned insertion file after the Pth video frame located before the Kth video frame, where P is the opposite of H.

[0077] For example, assuming that when the electronic device receives the first input, the first screen area displays the video frame a in the original video (i.e., the Kth video frame of the original video), and the user enters a value H in the drawing board interface through the second input, and H is an integer greater than 0, then: Figure 3 As shown, the display chip can insert the transition picture (ie, the insert file) between the Hth video frame and the H+1th video frame after the video frame a.

[0078] It should be noted that in the embodiments of the present application, the order of the first input and the second input may not be limited. For example, the first input may be executed first and then the second input, or the second input may be executed first and then the first input. The specific order may be determined based on actual usage requirements and is not limited in the embodiments of the present application.

[0079] In an embodiment of the present application, an insert file is inserted between any two video frames of the original video in the form of a separate video clip / video frame through a display chip to generate a target video. An independently set display chip performs frame insertion processing, which can improve the efficiency of inserting files into the video, ensure the smoothness and real-time performance of the video picture, and reduce the power consumption of the main control chip.

[0080] Optionally, in the embodiment of the present application, in implementation mode 2, the above step 202 can be specifically implemented by the following steps 202b and 202c.

[0081] Step 202b: In response to the first input, the electronic device fuses the inserted file with at least one video frame of the original video through the display chip to obtain at least one fused image.

[0082] Step 202c: The electronic device generates a target video through a display chip based on at least one fused image and a video frame in the original video that has not been fused.

[0083] The at least one video frame is determined based on user input (hereinafter referred to as the third input).

[0084] Optionally, in an embodiment of the present application, the display chip may fuse the inserted file with the at least one video frame based on the image parameters of the at least one video frame to obtain at least one fused image.

[0085] It can be understood that in the embodiment of the present application, the image parameters of the above-mentioned at least one fused image match the image parameters of the above-mentioned at least one video frame (the two are the same, or the matching degree of the two is greater than or equal to the second preset matching degree).

[0086] Optionally, in the embodiment of the present application, a special fusion algorithm is provided in the display chip, so that after the display chip receives the above-mentioned insertion file, the above-mentioned insertion file can be fused with at least one video frame in the original file based on the fusion algorithm to obtain at least one fused image. In this way, the speed of image fusion can be improved.

[0087] In an embodiment of the present application, when the electronic device needs to merge the inserted file with the at least one video frame, since the electronic device can directly merge the inserted file with the at least one video frame through the fusion algorithm in the display chip, the time for merging the inserted file with the at least one video frame can be shortened and the power consumption of the electronic device can be saved.

[0088] Optionally, in an embodiment of the present application, the fused image may include all the contents in the inserted file, or may include part of the contents in the inserted file (i.e., part of the inserted file), which may be determined based on actual usage requirements and is not limited in the embodiment of the present application.

[0089] Optionally, in the embodiment of the present application, the electronic device may determine a fusion position of the insert in the at least one video frame according to an input end position of the first input.

[0090] In the embodiment of the present application, the input end position of the first input may be the position of the inserted file in the first screen area when the user drags the inserted file to the first screen area and ends dragging.

[0091] In the embodiment of the present application, since the electronic device can determine the fusion position of the inserted file on the at least one video frame based on the input end position of the first input, it can ensure that the fusion position of the inserted file in the at least one video frame meets the user's actual fusion requirements, thereby improving the user experience.

[0092] Optionally, in an embodiment of the present application, the at least one video frame may be determined by the following four methods (specifically: the following methods 1 to 4).

[0093] Method 1

[0094] Optionally, in an embodiment of the present application, the user can enter at least one numerical value (each numerical value is an integer) in the drawing board interface through a third input, and the display chip can determine the video frame in the original video whose frame number is the same as the numerical value entered by the user as the above-mentioned at least one video frame.

[0095] For example, the user inputs the values ​​3 and 5 in the drawing board interface through the third input, then: the display chip can determine the 3rd frame and the 5th frame of the original video as the at least one video frame.

[0096] Method 2

[0097] Optionally, in the embodiment of the present application, the user may input a fusion period M through a third input, so that the display chip may determine the at least one video frame from the original video according to the fusion period M.

[0098] Specifically, assuming that the user inputs a fusion period M, and when the electronic device receives the first input, the first screen area displays the i-th video frame in the original video, where M and i are both positive integers; then: (1) the display chip can determine the video frames in the original video whose frame numbers are multiples of M as the at least one video frame mentioned above. (2) the display chip can determine the video frames in the original video whose frame numbers are greater than or equal to i and are multiples of M as the at least one video frame mentioned above. (3) the display chip can determine the video frames in the original video whose frame numbers are less than i and are multiples of M as the at least one video frame mentioned above.

[0099] Exemplarily, taking the above (2) as an example, assuming M=3, i=7, the display chip can determine the video frames in the original video whose frame numbers are greater than or equal to 7 and are multiples of 3, such as the 9th video frame, the 12th video frame, the 15th video frame, etc. in the original video, as the above at least one video frame.

[0100] Method 3

[0101] Optionally, in the embodiment of the present application, the user can input a value (a positive integer) through the third input, and then the display chip can determine the video frame whose frame number in the original video is greater than or equal to the value as the at least one video frame; or the display chip can determine the video frame whose frame number in the original video is less than the value as the at least one video frame. The specific determination can be made according to actual usage requirements.

[0102] For example, if the user inputs a value of 6 and selects all video frames whose frame numbers are greater than or equal to 6, the display chip can determine all video frames whose frame numbers are greater than or equal to 6 in the original video as the at least one video frame.

[0103] Method 4

[0104] Optionally, in an embodiment of the present application, the user can input a numerical value H in the drawing board interface through a third input, and the electronic device receives the frame number K of the video frame displayed in the first screen area when the first input is received. Then: the display chip can determine the video frame with a frame number H+K in the original video as the at least one video frame mentioned above; wherein K can be a positive integer, H can be a positive number, and K+H can be a positive integer.

[0105] For example, the value input by the user is 4 (ie, H=4), and when the electronic device receives the first input, the first screen area displays the 5th (ie, K=5) video frame of the original video, then: the display chip can determine the 9th video frame of the original video as at least one of the above-mentioned video frames.

[0106] In the embodiment of the present application, since the display chip can fuse the inserted file with at least one frame of the original video to obtain at least one fused image, and then generate a target video based on the at least one fused image and the video frames in the original video that have not been fused, compared to the original video, at least some of the video frames in the target video include newly added elements (such as the inserted file), which not only improves the flexibility of the electronic device in inserting files into the original video, but also maintains the continuity of the video images taken by the camera on the basis of enriching the elements of at least some of the video frames in the original video.

[0107] The video generation method provided in the embodiment of the present application is exemplarily described below with reference to the accompanying drawings.

[0108] Example 1: In the above implementation 1, during the video shooting process, if Figure 4As shown in (a) in the figure, the electronic device displays a video shooting interface on the display screen 40, and displays the video frame (i.e., the original video) captured by the camera in the video shooting interface; at this time, if the user needs to change the captured video screen, that is, to insert an image into the currently captured video, then: the user can input the video shooting interface, for example, the user can trigger the electronic device to turn on the fun drawing board function of the electronic device by inputting the selection menu in the video shooting interface. Thus, Figure 4 As shown in (b) of FIG. 4 , the electronic device can display the currently captured video (i.e., the original video) in the first screen area 41 of the display screen 40, and display the drawing board interface in the second screen area 42 of the display screen 40. Figure 5 As shown in (a) in the figure, the user can manually draw a five-pointed star image 51 in the drawing board interface (i.e., insert a file), and then the user can drag the five-pointed star image 51 to the first screen area 41 (i.e., the video shooting interface) (i.e., the first input). If the frame number of the video frame displayed in the first screen area when the electronic device receives the first input is 41, and the value corresponding to the second input is 30, then: the electronic device can insert the five-pointed star image 51 between the 71st (i.e., 41+30) frame and the 72nd frame of the original video through the display chip to generate the target video. In addition, the electronic device can continue to display video frames with video numbers greater than 41 in the target video in the first screen area, and as shown in FIG. Figure 5 As shown in (b) in FIG. 1 , the electronic device may display a five-pointed star image 51 in the target video in the first screen area 41 after displaying the 71st video frame in the target video.

[0109] Example 2: In the above implementation 2, during the video shooting process, if Figure 4 As shown in (a) in the figure, the electronic device displays a video shooting interface on the display screen 40, and displays the video frame (i.e., the original video) captured by the camera in the video shooting interface; at this time, if the user needs to change the captured video screen, that is, to insert an image into the currently captured video, then: the user can input the video shooting interface, for example, the user can trigger the electronic device to turn on the fun drawing board function of the electronic device by inputting the selection menu in the video shooting interface.
