Lossless sparse image display method, device and system

The invention discloses a lossless sparse image display method, device and system, and relates to the technical field of image processing. A lossless sparse image display method comprises: acquiring section information of a sparse image and sub-image information in a section, wherein the sub-images and the section are correspondingly arranged; packaging information except the pixel information ofeach sub-image into metadata, the metadata comprising more than one sub-metadata, and the sub-metadata being used for setting a display position of the pixel information; and during display, enablingthe display device to display the sub-images of each section of the sparse image to the corresponding positions of the screen according to the metadata of the sparse image. According to the invention,the memory data space of the memory for storing images can be saved, and the bandwidth requirement for reading the memory is reduced. 本发明公开了无损稀疏图像的显示方法、装置及系统，涉及图像处理技术领域。一种无损稀疏图像的显示方法，包括步骤：获取稀疏图像的区段信息和区段中的子图像信息，所述子图像与区段对应设置；将每个
