摘要: An image is conceptually divided into pixel blocks each having a plurality of pixels. RGB data representing the are converted luminance and color difference in NTSC form. Standard deviation values these calculated block compared with threshold values, so that classified two types. The respective types compressed at different compression rates to obtain compressed.
