Abstract
In an image processing apparatus, image data having a first resolution read from a first image memory is encoded by an arithmetic encoder and is converted into image data having a second resolution by an image reduction unit, and the image data having the second resolution is stored in a second image memory. Thereafter, the image data having the second resolution read from the second image memory is encoded by the arithmetic encoder and is converted by the image reduction unit into image data having a third resolution, and is stored in the first image memory in which the image data having the first resolution has been stored.
