Image processor and image processing method

Abstract

An image processor having an image compression unit to generate first compressed image data by dividing input image data into blocks of M×M pixels with regard to at least luminance signals (Y) of the input image data, wavelet-converting the image data in units of blocks, and reducing the number of bits by quantization, a memory to store the first compressed image data, a coordinate calculator to calculate coordinates to deform images by coordinate conversion and output coordinate information, a compressed image deforming unit to generate compressed deformed image data by reading out the first compressed image data stored in the memory while conducting coordinate conversion based on the coordinate information from the coordinate calculator, and a first image decompression unit to decompress the compressed deformed image data to obtain decompressed image data.
