Abstract

The invention discloses an image data compression device and an image data decompression device. The image data compression device performs image coding compression processing on the ith to-be-compressed image data sequence in each clock period, so that pipelined compression of image data is realized, the image data compression efficiency is improved, the image data compression process is simplified, the system complexity is reduced, and the data transmission efficiency is improved; according to the image data decompression device, the input to-be-decompressed image data sequence is subjected to pipelined decompression in parallel in each clock period, and one decompressed image data sequence containing n pixels is output in each clock period, so that the decompression efficiency is improved, and the time occupied by image decompression is shortened.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image data compression device and an image data decompression device. Background technique [0002] With the development of modern communication technology, businesses such as real-time visual communication, multimedia communication, network TV, and video surveillance have attracted more and more attention, and the types and data volumes of image information required to be transmitted are also increasing. To store images, image compression technology has become an urgent problem to be solved. [0003] Image compression refers to the storage and transmission of images with as little data as possible. Lossless compression means that the image data after decompression and restoration is exactly the same as the original image data. Image data compression generally has two processes of encoding and decoding. The source data is compressed and encoded by the encoder, and t...
