Abstract

The invention discloses an FPGA-based image video enhancement method, system and device. The method comprises the steps of obtaining grayscale data of a to-be-processed image; selecting an image enhancement method corresponding to the grayscale data; obtaining a grayscale mapping data table corresponding to the image enhancement method; obtaining mapping grayscale data of the grayscale data corresponding to the to-be-processed image by utilizing the grayscale mapping data table; and processing the mapping grayscale data to output an image. Therefore, the data calculation amount during image enhancement processing can be reduced.

Description

technical field [0001] The invention relates to the technical field of image and video processing, in particular to an FPGA-based image and video enhancement method, system and equipment. Background technique [0002] With the development of technology, the demand for high-quality real-time video display technology is expanding day by day. The traditional image enhancement is to use CPU (central processing unit) and other data processing systems based on von Leumann structure or DSP (Harvard structure). Although the image processing technology of the system has achieved good processing results, due to the large amount of image data itself, coupled with the complex data operation process of the image enhancement algorithm, the image enhancement faces a huge data operation burden. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide an FPGA-based image and video enhancement method, system, and device, which can reduce...
