Embodiment Construction

[0040] Such as figure 1 The logic diagram of the first embodiment of the large-scale image compression processing system of the present invention is shown, the image compression processing system includes FPGA10 and memory 20, and FPGA10 is embedded with segmentation module 11, two parallel compression modules 12, 12' and combination module 13. Wherein, the memory 20 is used for storing image data, and the image is a large-sized image. The segmentation module 11 is used to read the image to be processed from the memory 20, and divide the image into two image blocks, and assign them to the two compression modules 12, 12' respectively. The compression modules 12, 12' are used to compress the allocated image blocks to form multiple compressed data streams. Preferably, the compression modules 12, 12' compress each image block according to the JPEG compression standard. The combination module 13 is used to combine multiple compressed data streams. Finally, it should be noted tha...

Abstract

The invention discloses a large-scale image compression processing system and method. The image compression processing system includes a memory for storing image data. The image compression processing system also includes an FPGA, and the FPGA is embedded with: module, for reading the image to be processed from the memory, and dividing the image into multiple image blocks, and assigning them to multiple compression modules; multiple parallel compression modules, for respectively The image blocks are compressed to form multiple compressed data streams; the combination module is used to combine the multiple compressed data streams. The invention also constructs a large-size image compression processing method. By implementing the technical scheme of the invention, the efficiency of compressing large-size images is high, and the cost is low and the system is simple.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a large-size image compression processing system and method. Background technique [0002] With the continuous development of multimedia technology and communication technology, multimedia computers have put forward higher requirements for the storage and transmission of information data, especially digital image communication with a huge amount of data, so image compression and video compression have been widely used. [0003] At present, the image compression processing method is mainly the application of DSP or ASIC image processing chips. Most of these processing chips can process images with a maximum size of about 1080P, and are widely used in the field of image processing. However, if you want to compress larger-sized images, the image processing capabilities of this type of chip in terms of efficiency and speed are difficult to achieve. Therefore, if you want to compress a...
