1. An image processing device comprising:
a multimedia intellectual property (IP) configured to receive and process first image data and generate and use second image data;
a frame buffer compressor configured to compress the second image data into third image data and decompress the third image data into the second image data;
a memory configured to store the third image data and accessed by the multimedia IP,
wherein the frame buffer compressor performs compression or decompression when the multimedia IP accesses the memory, the frame buffer compressor operates in a lossy compression mode or a lossless compression mode, the lossless compressed third image data includes a first payload and a first header, the first header includes an index, and the lossy compressed third image data includes second payload only, and the second payload is compressed by a preset compression ratio,
where the index is a single value that maps to one of a plurality of different compression ratio ranges of the first payload.
