摘要： A refresh area is taken advantage of when a series of images are coded using Intra-frame coding and Inter-frame coding, a partial area of an image being forcefully Intra-frame coded (Intra MBs) in the refresh area. As the prediction mode for prediction of the Intra MBs inside the refresh area, a prediction mode is selected where the prediction is executable based on only the image that exists inside the refresh area.

摘要： An image encoding method for encoding an image using intra coding and interframe coding is offered. A refreshing area in which image refreshing is performed by intra coding is established. The refreshing area is shifted in an equal increment every frame such that the refreshing area traverses through the whole frame periodically. Where a macroblock that have passed through the refreshing area is interframe coded, a motion compensation vector of the macroblock is selected such that an image which has passed through the refreshing area is referenced.

摘要： The present invention relates to an image decoder which implements high speed image decoding with a low cost and simple configuration. By a stream dividing module, an input video stream is divided in units of frames as a plurality of frame rows for distribution. Each of plural decoders generates decoded images by decoding a distributed frame row. Of the decoded images generated by the decoders, reference images to be referred to when a subsequent frame is decoded is stored in a reference image frame memory. A timing control module receives information about stream distribution from the stream dividing module and controls the respective timings of decoding frames distributed to the decoders.

摘要： An image processing apparatus is configured to have units for compressing and expanding image data and an arbitrating unit for arbitrating control units for executing image processing so that the compressing and expanding units are located between the arbitrating unit and the control units respectively. The apparatus further includes the circuits for compressing and expanding the image data in a reversible manner and a nonreversible manner so that the compressing and expanding manner may be switched according to the image processing condition. When treating a large amount of image data, this configuration makes it possible to reduce the number of accesses to memory and make effective use of a bandwidth, thereby being able to reduce the power consumption. Since the bandwidth is reduced and the random access to memory is made possible, more image processing capabilities may be provided so that the operability of this apparatus is enhanced.
