PURPOSE: A method and an apparatus for displaying arbitrarily magnified high resolution images using compressed domain processing are provided to display large high resolution images in an efficient manner where a user easily changes the magnification of a region of the image to be displayed while conserving memory. CONSTITUTION: A method efficiently processes image data for display on a computer monitor. The method initiates with accessing image data stored in a compressed format. The image data is decompressed into a full scale image stored in a memory associated with a computer(130). Next, at least one pre-scaled image of the full scale image is generated(132). The at least one pre-scaled image has a magnification less than the full scale image. Then, a display scale of the image for presentation on a computer display is determined. Next, one of the full scale image and the at least one pre-scaled image that is closest in magnification to the display scale without being less than the display scale is selected(134). Then, the selected image being closest in magnification to the display scale is processed. Next, the processed image is displayed(140).
