Firstly, a 1920x1080 resolution image is obtained in an RGBY pixel array mode in a fixed extraction mode of adjacent pixels, and a field-shaped and triangle-shaped pixel array is taken as an example and briefly described as follows:
firstly, the signal conversion module can convert the signal formats coming from the RGB888 interface, the MIPI interface, the HDMI interface, the VGA interface and other interfaces, calculate to obtain the required data, and output one of the data according to the configuration.
The converted data is sent to a storage control module, the storage control module converts the image data into different forms through an algorithm and sends the different forms to a sampling control module, and meanwhile, the original image data is sent to a pixel sampling module.
And then the sampling control module detects whether the configuration signal sent by the register configuration module exists or not, if so, the configured sampling mode is sent to the pixel sampling module preferentially, and if not, the most suitable sampling mode is selected according to the conditions of the change speed, the complexity and the like of the image data sent by the storage control module and sent to the pixel sampling module.

The extracted array reserves the original 2x2x3 sub-pixel RGBY pixel components, and can display the original image more accurately. After the operation, the number of sub-pixels needed at the display end is much smaller than the previous number of pixels, and the area is also much smaller. This approach is suitable for low complexity or regularly changing images using decimated pixels.
Secondly, a 1920x1080 resolution image is obtained in an adjacent pixel mixing and extracting mode, and an RGBY mode, a field-shaped and strip-shaped sub-pixel array are taken as an example to briefly describe:
firstly, the signal conversion module can convert the signal formats coming from the RGB888 interface, the MIPI interface, the HDMI interface, the VGA interface and other interfaces, calculate to obtain the required data, and output one of the data according to the configuration.
The converted data is sent to a storage control module, the storage control module converts the image data into different forms through an algorithm and sends the different forms to a sampling control module, and meanwhile, the original image data is sent to a pixel sampling module.
And then the sampling control module detects whether the configuration signal sent by the register configuration module exists or not, if so, the configured sampling mode is sent to the pixel sampling module preferentially, and if not, the most suitable sampling mode is selected according to the conditions of the change speed, the complexity and the like of the image data sent by the storage control module and sent to the pixel sampling module.
And finally, the pixel sampling module performs pixel space extraction on the original image data in one or more modes according to the sent control signal, and sends the extracted image data and the selected sampling mode as the control signal to the display module.
The display module selects the corresponding display array according to the input sampling mode, and the corresponding image can be successfully displayed.
The specific way of rectangular extraction is shown in fig. 5, the rectangular extraction is shown in fig. 6, and each 2 × 2 pixel array may be extracted in different combinations, each of which may be any permutation and combination of extraction:
the sub-pixel No. 1 in FIG. 5 is a red pixel, and the red sub-pixel component in the first row and the first column in the original video frame is extracted; the sub-pixel No. 2 in FIG. 5 is a green pixel, and the extracted component of the green sub-pixel in the first row and the second column of the original video frame; the sub-pixel 1921 in fig. 5 is a blue pixel, and the extracted blue sub-pixel component in the second row and the first column in the original video frame; the sub-pixel 1922 in fig. 5 is a yellow pixel, and the yellow pixel component of the second row and the second column in the original video frame is extracted. The sub-pixel No. 3 in FIG. 5 is a blue pixel, and the extracted blue sub-pixel component is the third column in the first row of the original video frame; the sub-pixel No. 4 in FIG. 5 is a yellow pixel, and the extracted yellow pixel component is the fourth column of the first row in the original video frame; the sub-pixel 1923 in fig. 5 is a red pixel, and the red sub-pixel component in the third column of the second row in the original video frame is extracted; the sub-pixel 1924 in fig. 5 is a green pixel, and the component of the green sub-pixel in the fourth column of the second row in the original video frame is extracted.
Similarly, the sub-pixel number 1 in fig. 6 can also be a red pixel, and the extracted red sub-pixel component is the first row and the first column in the original video frame; the sub-pixel No. 2 in FIG. 6 is a green pixel, and the extracted component of the green sub-pixel in the first row and the second column of the original video frame; the sub-pixel No. 3 in FIG. 6 is a blue pixel, and the blue pixel components in the first row and the third column in the original video frame are extracted; the sub-pixel No. 4 in FIG. 6 is a blue pixel, and the extracted sub-pixel is the blue sub-pixel in the fourth column of the first row in the original video frame.

The extracted array reserves the original 2x2x3 sub-pixel RGBY pixel components, and can display the original image more accurately. After the operation, the number of sub-pixels needed at the display end is much smaller than the previous number of pixels, and the area is also much smaller. The mixed extraction mode can effectively improve the display efficiency and simultaneously avoid the missed extraction when a single row of pixels or a single column of pixels has a certain single color.
Thirdly, a 1920x1080 resolution image is obtained in a continuous frame fixed extraction mode, an RGBY pixel array mode is adopted, and a field-shaped pixel array is described as an example in brief:
firstly, the signal conversion module can convert the signal formats coming from the RGB888 interface, the MIPI interface, the HDMI interface, the VGA interface and other interfaces, calculate to obtain the required data, and output one of the data according to the configuration.
The converted data is sent to a storage control module, the storage control module converts the image data into different forms through an algorithm and sends the different forms to a sampling control module, and meanwhile, the original image data is sent to a pixel sampling module.
And then the sampling control module detects whether the configuration signal sent by the register configuration module exists or not, if so, the configured sampling mode is sent to the pixel sampling module preferentially, and if not, the most suitable sampling mode is selected according to the conditions of the change speed, the complexity and the like of the image data sent by the storage control module and sent to the pixel sampling module.
And finally, the pixel sampling module performs pixel space extraction on the original image data in one or more modes according to the sent control signal, and sends the extracted image data and the selected sampling mode as the control signal to the display module.
The display module selects the corresponding display array according to the input sampling mode, and the corresponding image can be successfully displayed.
