Abstract

The invention relates to a method for multipath decomposition of an ultrahigh-resolution image. The method comprises the following steps: step 1, determining the resolution of an ultrahigh-definitionimage; step 2, determining the number of multipath decomposition, wherein the number of paths of multipath decomposition of the ultra-high-definition image is not less than two; : step 3, determininga picture decomposition form; step 4, performing effective row caching on an input image, wherein the number of the row caches is not less than one row; : step 5, outputting the decomposed image by using a time sequence driving module and corresponding control logic; wherein the control logic is related to a picture decomposition form; and step 6, driving display equipment by the decomposed imagethrough a video interface. RAM resources in an FPGA chip can be utilized; the high-resolution image is effectively subjected to row caching, the decomposed image is output through the time sequence output module and the logic control module, the time delay of the video processing system is reasonably and effectively reduced, and meanwhile, external memory resources are prevented from being used.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for demultiplexing an ultra-high resolution image. Background technique [0002] As the image resolution becomes higher and higher, the information conveyed by the image becomes more and more abundant. But most display devices still stay on low-resolution displays. During the transmission process of traditional high-resolution images, high-speed, high-resolution images are processed in the FPGA, and the method of speed reduction will be adopted. Take a 3840*2160 image with a frame rate of 60Hz as an example, and the pixel clock is 594Mhz. In the transmission process, the input image can be processed in a 4-wire system, so that the pixel clock frequency can be 1 / 4 of the original, that is, 148.5Mhz. That is, every 4 pixels of each line of the serial image are output in parallel, and the frequency of the driving clock is reduced to 1 / 4 of the original. The tra...
