Abstract: 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.

Abstract: 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.
