Abstract

The invention provides an image processing method, an image processing device, an image display method and an image display device, and the method comprises the steps: dividing a plurality of row dataof image data into a plurality of row groups according to the number of colors, and enabling the number of colors of the row data in each row group to be in direct proportion to the number of the rowdata in the row group, so that dynamic line division of the image data according to the color complexity can be realized, that is, the line number of the line groups can be properly increased for anarea with relatively complex image colors, and the line number of the line groups can be properly reduced for an area with relatively simple image colors, so that the influence of compression on the image quality of the image is reduced. Besides, before the image is compressed, the identification code is added to ensure that the image data is accurately compressed and transmitted according to therow groups divided by the dynamic sub-rows, and a basis is provided for subsequent decoding display completion.

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. Contents of the invention [0004] In view of this, in order to solve the above proble...
