Abstract
According to one embodiment, an image processing apparatus connectable to a main memory in which a plurality of pixel values of unconverted image is stored and a cache memory including a plurality of cache blocks. The apparatus includes a counter, a coordinate determination module, a memory controller, a cache access module, a pixel value calculator, and an output module. The counter determines a coordinate within converted image according to a predetermined execution sequence. The coordinate determination module determines a plurality of coordinates within unconverted image of the pixel values of unconverted image necessary to calculate a pixel value of converted image corresponding to the coordinate within converted image. The memory controller transfers the pixel values of unconverted image stored in the main memory to the cache blocks corresponding to each of the coordinates within unconverted image. The cache access module reads out all the pixel values of unconverted image necessary to calculate the pixel value of converted image from the cache blocks. The pixel value calculator calculates the pixel value of converted image by referring to the pixel values of unconverted image read out by the cache access module. The output module outputs the pixel value of converted image.
