ABSTRACT:
A frame memory of an image recording apparatus includes a first frame memory for storing image data having a large number of pixels per unit area and a small number of gradations per pixel and a second frame memory for storing image data having a small number of pixels per unit area and a large number of gradations per pixel. Image data representing a character, a graphic figure or similar items requiring a high resolution is stored in the first frame memory, while image data inputted through a scanner or similar device and having a large number of gradations is stored in the second frame memory. In recording an image, the image data stored in the first frame memory is converted to image data having a large number of gradations, and the image data stored in the second frame memory is converted to image data having a high resolution, and recording is effected on the basis of these image data. As a result, images are recorded with high image quality by using a small-capacity frame memory.
