A method and apparatus for partially up/downscaling an image encoded on a macroblock basis utilizing a computer. The method and apparatus performs operations of: creating map data of the encoded image so as to be able to find a filestream position corresponding to a macroblock in the encoded image to be decoded; creating a shrunken image of the encoded image; receiving a first control request from a user to display a first part in the encoded image; displaying on a display device, a second part in the shrunken image corresponding to the first part in the encoded image; decoding macroblocks containing the first part in the encoded image, using the map data; and displaying on the display device, the first part in the encoded image using the decoded macroblocks so as to replace the second part in the shrunken image therewith.

Partial expansion method of encoded images and image processing apparatus

A method and apparatus for partially up/downscaling an image encoded on a macroblock basis. The method and apparatus performs operations of: storing the encoded image; creating map data from bitstream of the encoded image to decode at a least one macroblock of the encoded image, creating a shrunken image of a predetermined size based on resolution of a display device, storing the map data and the shrunken image so as to relate with the encoded image; outputting the shrunken image related with the encoded image to be displayed based on a control request received from an input device; determining at least one macroblock to be decoded based on a display area of the shrunken image; partially decoding the encoded image for the determined macroblock using the map data; and outputting to the display device, the image data of the display area of the partially decoded image.
