Abstract
An image processing method and apparatus which can obtain an image, at a desired resolution, far from degradation in image at a high speed is disclosed. Input original image data is converted into hierarchical codes by a JBIG-CODEC 95, and the codes of the layers are stored in a memory. To obtain image information at a desired resolution, a code necessary for representing an image having, of the resolutions which can be represented by the hierarchical codes stored in the memory, a resolution hither than and closest to the desired resolution is selected to execute decoding processing in the JBIG-CODEC 95, thereby obtaining reproduced image data. A resolution conversion unit 96 converts the resolution of the reproduced image into a desired resolution by using, e.g., linear interpolation and outputs the converted image data.
