Abstract
An image processing device includes: a controller configured to receive information for displaying at least a portion of an image, and in response thereto to generate a scale ratio K for scaling compressed image data corresponding to the image; a partial image decoder configured to receive the compressed image data and the scale ratio and in response thereto to decode and scale the compressed image data by the scale ratio K and to output a portion of the decoded and scaled image data, wherein the portion corresponds to an area of the image to be displayed on a display device; a frame buffer configured to store the portion of the decoded and scaled image data output by the partial image decoder; and a video processor configured to receive the data from the frame buffer and to further scale the data for display on the display device.
