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-size image compression processing system and a method. The image compression processing system comprises a storage device used for storing image data and an FPGA. The FPGA is embedded with a cutting module, a plurality of parallel compression modules and a combination module, wherein the cutting module is used for reading a to-be-processed image in the storage device, cutting the image into a plurality of image blocks and distributing the image blocks respectively to the plurality of compression modules; the compression modules are used for carrying out compression processing on the distributed image blocks respectively so as to form a plurality of compression data flows; and the combination module is used for combining the plurality of compression data flows. The invention also provides a large-size image compression processing method. When the technical scheme of the invention is applied, the efficiency of carrying out compression processing on the large-size image is high, 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...
