    • PROBLEM TO BE SOLVED: To shorten a delay from an instruction to reproduce compression-encoded video until completion of drawing of a decoding result of a head frame on a frame buffer.SOLUTION: An image processing device having a video decoder for decoding video compression data in which a unit block is composed of intra-frame prediction encoding data and one or plural pieces of inter-frame prediction encoding data subsequent thereto, is provided with a still image decoder for decoding still image data subjected to irreversible compression encoding. Meanwhile, with respect to the video compression data, still image compression data obtained by applying the irreversible compression encoding to a still image of the head frame thereof is associated with the head frame. Then, when the video compression data is decoded, the still image compression data is decoded by the still image decoder in parallel, and a decoding result by the still image decoder is drawn on a frame buffer instead of a decoding result by the video decoder with respect to the head frame.
    • 要解决的问题:缩短从再现压缩编码视频的指令到完成对帧缓冲器上的头帧的解码结果的绘制的延迟。 解决方案:一种具有用于解码视频压缩数据的视频解码器的图像处理装置,其中单位块由帧内预测编码数据和随后的一帧或多帧帧间预测编码数据组成, 用于解码经受不可逆压缩编码的静止图像数据的静止图像解码器。 同时,对于视频压缩数据,通过对其头部帧的静止图像应用不可逆压缩编码获得的静止图像压缩数据与头部帧相关联。 然后,当视频压缩数据被解码时,静止图像解码器并行解码静止图像压缩数据,并且通过静止图像解码器将解码结果绘制在帧缓冲器上而不是由视频解码器的解码结果, 尊重头部框架。 版权所有(C)2012,JPO&INPIT
