| 摘 要： | JPEG2000是ISO/ITU-T既推出JPEG静态图像压缩标准后推出的有一种高效能图像压缩标准。JPEG2000相比JPEG压缩算法,具有更高的压缩比,更高的图像压缩质量,其特有的具有图像多分辨率的特点,使其适合多种应用场合。在对JPEG2000压缩标准作了简介后,针对ADV202芯片提出了JPEG2000压缩解压缩实现方案。该实现方案,具有体积小、功耗低、成本低、调试简单的特点。

| Abstract: | After the issue of JPEG static image compression standard,JPEG2000 is another high-efficiency image compression standard issued by ISO/ITU-T,which has such characteristics as higher compression ratio and higher compression quality comparing with JPEG compression algorithm.JPEG2000 is suitable for multiple applications because of its unique feature of multi-resolution of image.In this paper,after a brief introduction to JPEG2000 compression standard,JPEG2000 compression and decompression implementation scheme is proposed for ADV202 chip,which has such characteristics as small size,low power consumption,low cost and easy adjustment. |
