Abstract
There is provided an image processing apparatus. A splitting unit splits an image into a block. A quantization unit performs quantization of the block using a plurality of methods. A calculating unit calculates a distance between the block and a result of the quantization. A selecting unit selects a quantization result of the quantization unit using the distance. An encoding unit performs fixed-length encoding of the quantization result selected by the selecting unit. The quantization unit includes a first quantization unit that preserves texture in the block, and a second quantization unit that represents pixels in the block in a plurality of colors.
