Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative work fall within the protection scope of the present application.

Please refer to FIG. 1, which is a schematic flowchart of an embodiment of an image processing method of the present application. The image processing method in this embodiment can be used in electronic devices with a screen or an external screen, such as a TV set-top box and the like. Among them, the image processing method includes:

Step S12: Receive a video signal;

Among them, the video signal can be received by the electronic device directly from the outside through the data line, downloaded from the cloud, or can also be directly obtained from the memory of the electronic device.

In this embodiment, the received video signal may be a 4K progressive display signal that can achieve 3840×2160 UHD resolution. Of course, it may also be processed by the solution in this embodiment to meet the screen output requirements and users The video signal for viewing needs is not specifically limited here.

Step S14: Detect the type of video signal;

In this embodiment, the video signals may be different types of video signals. For example, they may be divided into different types according to the format of the video signal, the size of the data contained in the video signal, and the level of fluency.

Specifically, it can be divided into different types according to the display method of the video signal, for example, a progressive display type, an interlaced display type, and the like.

Step S16: Process the video signal according to the type of the video signal to generate processed video data;

It should be noted that, in this embodiment, when the types of video signals are different, the processing methods used are also different. Specifically, the processing method mainly includes the conversion processing of the type of the video signal, and the back-end processing of the video signal.

For example, after detecting the type of the video signal, it can be further determined whether the type of the video signal satisfies the user's viewing and screen display requirements. When the judgment result is yes, the back end of the video signal can be directly executed Processing, and when the judgment result is negative, you can first perform type conversion processing on the video signal, and then further perform back-end processing.

Specifically, please refer to FIG. 2. In an application scenario, the video signal may include video data of the first type, video data of the second type, and so on. Among them, the first type of video data has a large data volume and takes up a lot of storage space, which cannot meet the screen display requirements and user viewing requirements in this embodiment, and further data conversion processing is required. The second type of video material has a smaller amount of data, and can be directly processed by the back-end without conversion processing. Among them, step S16 includes:

Step S161: When it is determined that the video signal is the first type of video data, the first type of video data is converted into the second type of video data, wherein the amount of the second type of video data is less than the first type of video data ;

It should be noted here that for the same video signal, after the first type of video data is converted to the second type of video data, the amount of data becomes smaller, thereby reducing the storage space requirements and reducing the burden on electronic devices . Among them, the specific conversion method can be determined according to demand.

In an application scenario, referring to FIG. 3, when converting the first type of video material into the second type of video material, step S161 further includes:

Step S1611: Grouping the first-type video data of each frame to generate multiple sets of image data, wherein each set of image data includes M lines of image data, and M is a positive integer greater than or equal to 2;

Understandably, each frame of video data may include multiple lines of image data. In this embodiment, each frame of video data is grouped in units of rows, and each group obtained includes at least two lines of image data, for example, may include 2 lines, 3 lines, etc. The specific number of lines may be set according to actual needs.

Step S1612: process each group of image data, reserve one line of image data as writing data of the group of image data, and delete other lines of image data, thereby converting the first type of video data into the second type Video material.

In this embodiment, according to the situation of grouping each frame of the first type of video data, each group of obtained image data is deleted, so that each group of image data only retains the M lines of image data in the group Just one line.

Specifically, when deleting the image data of each group, one line can be randomly retained and the image data of the other lines can be deleted; or the image data of a specified line can be retained according to certain rules, and the remaining The image data of other lines, for example, when M is 2, the first line of each group of image data can be retained, and the image data of the second line can be deleted and converted into the second type of video data after processing , Can reduce the amount of video signal data by half.

For example, the received video signal is the first type of video data. The first type of video data is grouped into M groups of each group and divided into N groups. When processing each group of image data, each group Only one of the M lines is reserved, and the second type of image data obtained only contains N lines of image data in the first type of image data, thereby greatly reducing the amount of data.

In an application scenario, please refer to FIG. 4, step S1612 includes:

Step S16121: reserve one line of image data as writing data of the group of image data, and delete the image data of other lines;

The specific operation mode in this step is the same as the description in the above step S1612. For the related details, please refer to the above steps, which will not be repeated here.

Step S16122: combine the retained image data with the empty data to generate the second type of video data.

In this application scenario, the reserved data and the empty data can be combined according to a preset or a combination method set according to user needs to obtain a complete second type of video data that can be normally displayed on the screen.

Specifically, in an application scenario, please refer to FIG. 5, step S161 further includes:

Step S1613: Divide the first-type video data of each frame into odd-line data and even-line data;

Step S1614: According to the preset requirements, select one of the odd-line data and the even-line data in the first type of video data for retention, and delete the other type of data, thereby converting the first type of video data into the second Type of video material.

In this embodiment, the odd-line data and the even-line data can be divided according to the writing order of the video data.

Specifically, when converting the video data, the first type of video data in each frame can be separated first to obtain the corresponding odd-line data and even-line data, and then the odd-line data or even-number data can be further reserved as required Line data, delete the data not selected for retention, and can further combine the reserved odd line data or even line data with empty data to convert the first type of video data into the second type of video data. Half of the second type of video data is valid data and the other half is empty data, which can greatly reduce the amount of video signal data.

Step S162: Perform back-end processing on the second type of video data to generate processed video data.

It should be noted that, in this embodiment, the second type of video material includes video material that originally belongs to the second type, and also includes video material converted from the first type to the second type after conversion processing. When performing back-end processing on the second type of video data, for example, the second type of video data can be processed according to the user's use requirements, such as according to the playback conditions set by the user to obtain video data that meets the requirements .

Specifically, referring to FIG. 6, in an application scenario, step S162 includes:

Step S1621: Perform image quality processing on the second type of video material;

Among them, the image quality processing in this embodiment may include processing of the brightness, contrast, color temperature, color saturation, hue, etc. of the second type of video data to improve the quality of the image display, thereby further enhancing the user's perception Experience.

Step S1622: Perform sequential processing on the second type of video material that has undergone image quality processing;

Specifically, when performing timing processing, the processing may be performed according to a preset clock and synchronization signal timing. After the sequential processing, the frequency of the second type signal can be set, for example, it can be set to a preset output frequency, or set to another frequency according to the user's use requirements.

Step S1623: Perform packet processing on the second type of video material that has undergone time series processing to generate processed video material.

Specifically, after the sequential processing, a header of the second type of video data may be added, and then packet processing is performed, thereby obtaining video data that can be transmitted to the screen and written to the screen and displayed by the screen.

Step S18: Write the processed video data on the screen for display.

It should be noted that in this embodiment, after the processed video data is obtained, the processed video data is the second type of video data, and the second type of video data consists of a part of valid data and a part of empty data Combined to form, when writing to the screen, empty data can be written to the same data as the corresponding valid data. As described above, the first type of video data of each frame is grouped, each group contains M lines of image data, one line of the M lines of image data is retained, and the image data of other lines is deleted. When writing video data to the screen, M gate channels are opened at the same time, and in each row of each corresponding group, the same image data as the one row of image data retained in the group is simultaneously written. Obviously, this can not only reduce the amount of data written, but also reduce the writing time of each frame of video data, and can make the display screen fill the entire screen when the amount of data is reduced.

It should be noted that in the above method, by detecting the received video signal and grouping the video data of each frame of the video signal according to the type of the video signal, a line of image data is retained in each group to delete the remaining Image data, and further back-end processing and display on the screen, because the original video signal data is deleted, which can reduce the amount of video signal data, thereby reducing the storage space occupied by video data , Reduce the burden on electronic devices, and further provide technical support for improving the smoothness of the screen display.

It should be pointed out that in one embodiment, the second type of video data can be processed in sequence according to the original output frequency. In this case, after writing the processed video data on the screen, the original output frequency can be used , Sequentially output the second type of video data of the current frame to the screen for display. At the same time, after writing the second-type video data of the current frame and before writing the second-type video data of the next frame, the backlight of the screen can be turned off.

Please refer to FIG. 6, taking the received video signal as the progressive video signal in the 4K display technology as an example, and the original output frequency is 60 Hz. According to the image processing method in the above embodiment of the present application, after receiving the video signal, it is detected that the type of the video signal is progressive display. In this embodiment, the amount of video signal data displayed progressively is large. Storage space requirements are high, so it needs to be converted into interlaced video signals. Specifically, each frame of video data of the video signal is divided into odd-line data and even-line data. In this example, during data conversion, the odd-line data is retained, the even-line data is deleted, and the retained odd-line data is blank Combination of data to get video data displayed in interlaced display. After converting to interlaced video data, further image quality processing and sequential processing of the interlaced video data according to the original 60Hz output frequency, and after sequential processing, further packet processing, and according to the original Some 60Hz output frequency is output to the screen for display. Specifically, when writing video data, two gate channels are opened at the same time, and the odd-numbered lines and the even-numbered lines deleted accordingly are written to the same data as the odd-numbered lines. Data, so that in the case of deleting even-numbered lines of data, the final displayed screen can still fill the entire screen. Compared with before processing, the processed video data only retains half of the original video data line 2160 lines, that is, 1080 lines, and at the same time open two gate control channels at the same time, so that each frame of video data The writing time is reduced by half, which in turn increases the vertical blank gap. In this example, the backlight is further disconnected in the vertical blank gap, so that the effect of saving power consumption can be further achieved.

In addition, in this embodiment, the OD (Over drive) technology may be further combined to increase the refresh rate of the final display image, thereby reducing the motion picture freeze.

In another embodiment, when performing back-end processing on the second type of video data, the second type of video data may be processed in time series according to an output frequency that is M times the original output frequency, and according to the adjacent two The video material of the second type of frame generates the video material of the intermediate transition frame. When outputting through the screen, the second-type video data of the current frame and the video data of the intermediate transition frame are sequentially output to the screen for display according to an output frequency that is M times the original output frequency.

。本實施方式中，對第二類型的視頻資料依據原有輸出頻率的M倍的輸出頻率進行時序處理，從而使得在原有的輸出一幀視頻資料的時間中對應輸出M幀視頻資料。In this embodiment, when converting the first type of video data into the second type of video data, each frame of the first type of video data is grouped, each group includes M lines of image data, and each group When the image data is processed, only one of the M lines of image data is kept as the write data of the group of image data, and the image data of the other lines are deleted, so that the processed video is finally written on the screen Data, the output time becomes the original output time

. In this embodiment, the second type of video data is subjected to timing processing according to an output frequency that is M times the original output frequency, so that M frames of video data are correspondingly output during the time when the original frame of video data is output.

Further, the M-frame video material in this embodiment includes the second-type video material of the current frame and the M-1 frame intermediate transition frame video material. The video material of the intermediate transition frame is a video material generated according to the second type video material of the current frame and the second type video material of the next frame adjacent to the current frame.

Please refer to FIG. 7 for details. In this embodiment, the received video signal is also a progressive video signal in the 4K display technology. The original output frequency is 60 Hz. Among them, the data conversion is similar to the conversion process in the example shown in FIG. 6 above, and will not be repeated here. It should be noted that after converting to interlaced video data, further image quality processing and the interlaced display The video data is processed in time sequence at an output frequency that is twice the original output frequency. After the time sequence processing, further packet processing is performed and written to the screen for display. Similarly, when writing video data, open two gated channels at the same time, and write the odd-numbered lines and the even-numbered lines correspondingly deleted to the same data as the odd-numbered lines at the same time, so that the final displayed picture can cover the entire picture Screen. At the same time, at the time of output, the video data of the intermediate transition frame is generated based on the two adjacent video materials, and the converted interlaced video data and the output video data at the output frequency of 120 Hz are output at twice the original 60 Hz output frequency, and The video material of the generated intermediate transition frame. The same as the example in Figure 6 above, because the processed video data only retains half of the original video data line number 2160 lines, that is 1080 lines, and at the same time open two gated channels for writing, so that each The writing time of frame video data is halved. In this way, the output frequency can be increased to 120Hz without increasing the amount of video data and without affecting the normal display, which can improve the refresh rate of the picture and reduce the motion picture. Stuck; In addition, due to the generation and output of the video material of the intermediate transition frame, the display screen is more coherent, which can improve the smoothness of the image display.

In addition, in this embodiment, the OD technology may be further combined to increase the refresh rate of the display image, thereby reducing the motion picture freeze.
