Abstract

An image processor includes an image memory which stores compressed and coded image data representing an image, the compressed and coded image data includes first data representing the image with a low resolution and second data representing the image with a high resolution. A generating unit generates image data of the low resolution and image data of the high resolution, by decoding the compressed and coded image data stored in the image memory. Area data is provided representing a partial area of the image, the area data including first area data representing the partial area with the low resolution and second area data representing the partial area with the high resolution. A first processor processes the image data of the low resolution generated by the generating unit in accordance with the provided first area data of the low resolution. A second processor processes the image data of the high resolution generated by the generating unit in accordance with the provided second area data and prints an image on the basis of the processed image data of the high resolution.
