Apparatus and method for processing hierarchically-coded image data includes structure and steps for storing hierarchically-coded image data and providing a first image data by decoding the hierarchically-coded image data. The first image data having a first resolution is stored in a display memory. The stored first image data is displayed on a display, and an area within the displayed first image is designated for a second image. The second image data is provided by decoding the hierarchically-coded image data and is representative of an image in the designated area of the first image. The second image data having a second resolution is stored in a portion of the display memory while the memory maintains the first image data stored therein. Finally, the display displays a combined image including the first image having the first resolution and the second image having the second resolution.
