ABSTRACT:
A moving picture reproducing device includes a compressed data buffer, a display size obtaining unit, a resolution selecting unit, four kinds of resolution decoding units, and a frame data buffer. Compressed moving picture is received by the compressed data buffer and decoded in one of the four kinds of resolution decoding units. The display size obtaining unit obtains a display size of the decoded moving picture when the image is displayed on a display device. The resolution selecting unit selects one resolution decoding unit from the four kinds of resolution decoding units, according to the display size obtained by the display size obtaining unit. When the moving picture is reduced and displayed on the display device, it is not required to decode the moving picture in an original resolution. The moving picture reproducing device decodes the compressed moving picture in a necessary and the minimum resolution.
