摘要： An image processing apparatus includes the following elements. A specifying unit specifies a blank region of an image of image data by using coefficient data which is decoded from encoded data, the encoded data being obtained by encoding coefficient data generated from the image data. A dividing unit divides the decoded coefficient data into first components and second components. An eliminating unit eliminates the blank region specified by the specifying unit from the first components divided from the decoded coefficient data by the dividing unit. A synthesizing unit combines the first components from which the blank region has been eliminated by the eliminating unit with the second components divided from the decoded coefficient data by the dividing unit.

摘要： In case of decoding by a software process, in the process 1, video data of a decoded frame corresponding to a management ID stored at the head of an output FIFO 4 at its time point is read out and outputted. In the process 2, audio data is decoded. In the process 3, the video data is decoded. The decoded video data is stored in a video frame buffer and its management ID is stored in the output FIFO 4 in the outputting order. When the process 3 cannot be finished, the process 3 is interrupted during the process and the image of the frame stored at the head of the output FIFO 4 is outputted. After that, when the process 2 is finished, the decoding process of the process 3 which was temporarily interrupted is restarted. In case of performing the encoding by the software process, an encoding amount of the video data as a processing target of the encoding is predicted. Subsequently, whether an empty capacity enough to store the data of the predicted encoding amount exists in a code buffer or not is discriminated. If it is determined that there is the empty capacity, the encoding is started and the video data in which the encoding was finished is deleted from the video frame buffer. The encoding is temporarily interrupted when a reading process or the like of the video data is performed.

摘要： A data processing device able to generate prediction image data at short time even in the case of using a motion vector indicating outside an effective pixel region. A motion compensation circuit generates reference outside the effective pixel region and writes it into a memory based on reference image data inside the effective pixel region stored in the memory through decoding. A motion compensation circuit, in the case that the motion vector MV indicates outside the effective pixel region, generates prediction image data based on reference image data outside the effective pixel region stored in the memory.

摘要： A flexible software-based decoding system with decoupled decoding timing and output timing. In one embodiment, a computer software implemented method of decoding a data stream comprising encoded video data is provided. In this embodiment, the software method comprises the step of maintaining a number of already decoded and ready-for-output frames in a frame buffer. The method also comprises the step of decoding a first encoded frame of the data stream to generate an additional decoded frame. The method further comprises the step of outputting a first of the decoded frames before decoding of the first encoded frame is completed if the decoding step requires more time than a predefined frame output time to complete. Moreover, in this embodiment, the method comprises the step of adding the first additional decoded frame to the frame buffer. In this embodiment, real-time output is maintained irrespective of whether completion of the decoding step requires more time than the predefined frame output time for particular frames. In one embodiment, the method further comprises the step of decoding a second encoded frame of the data stream substantially immediately upon completion of the decoding step to generate a second additional decoded frame, provided that the completion of the decoding step requires more time than the predefined frame output time, and also the step of adding the second additional decoded frame to the frame buffer.
