Abstract

The present invention provides an image processing method, a processing device, an image display method, and a display device. The method includes: dividing a plurality of line data of image data into a plurality of line groups according to the number of colors, and the color of the line data in each line group The amount is proportional to the amount of row data in that row grouping. This can realize the dynamic division of image data according to the color complexity, that is, the number of rows grouped can be appropriately increased for areas with relatively complex image colors, and the number of rows grouped can be appropriately reduced for areas with relatively simple image colors, so that Reduce the impact of compression on image quality. In addition, before image compression, adding an identification code can ensure that the image data is accurately compressed and transmitted according to the row grouping divided by the dynamic branch, and provide a basis for subsequent decoding and display.

Description

technical field [0001] The present invention relates to the technical field of image display, and more specifically, to an image processing method, a processing device, an image display method, and a display device. Background technique [0002] With the development of electronic equipment, the resolution and refresh rate of display screens have been continuously improved, and the amount of data transmitted by images has also increased significantly. However, the bandwidth of the current common transmission interface D-PHY 4Lane can no longer meet the transmission requirements. [0003] In order to solve the above problems, a standard image compression protocol (Display Stream Compression, DSC) is proposed in the industry. However, the current compression transmission scheme using the DSC compression protocol will have a greater impact on the image quality of the decompression display. SUMMARY OF THE INVENTION [0004] In view of this, in order to solve the above problem...
