    摘要: The present invention provides an image encoding device which does not necessitate reference of a quantization parameter between consecutive macroblocks across a parallel processing area boundary without forming slices. The image encoding device encodes a macroblock of an encoding target image by parallel processing sequentially from the top of a parallel processing area, and possesses an encoding element for every parallel processing area. When all the quantized orthogonally-transformed coefficients of a top macroblock of the parallel processing area are zero, the encoding element adds a non-zero coefficient to a part of the coefficients, making the coefficients non-zero. Accordingly, generation of a skip macroblock in the top macroblock of each parallel processing area is suppressed. Since slice formation is not necessary, the prediction over a parallel processing area boundary is applied, and encoding efficiency improves. Errors are not generated in decoding and the decoded image quality does not deteriorate.

    摘要: To reduce a processing load of an external CPU, when a large amount of data is initially set frequently to an image coding/decoding device. The image encoding/decoding device (data processing device) includes a first circuit and a second circuit for providing initial setting to a plurality of image processing modules (processor units), wherein the image encoding/decoding device does not receive information, which is initially set to the image processing modules, directly from the external CPU, and control information for the initial setting is set to the first circuit from the CPU. The second circuit reads in initial setting information and setting-target information of the initial setting information from outside using the control information set in the first circuit and transfers the initial setting information to the image processing module according to the read-in setting-target information.

    摘要: A moving image processor includes a first and a second moving image processing unit which are able to perform parallel operation, and a data transfer unit having a first buffer and a second buffer. The first moving image processing unit processes macroblocks MB00, - - - , of one row of one image sequentially, and the second moving image processing unit processes macroblocks MB10, - - - , of the next row sequentially. The first and the second moving image processors include a first and a second deblocking filters, respectively. Operation timing of the second filter is delayed by the processing time of two macroblocks, compared with operation timing of the first filter. The processing results of the first filter and the second filter are transferred to an external memory via the first buffer and the second buffer of the transfer unit.

    摘要: In terms of the transmission of the coding method, it is ensured to decode information coded according to the intra-frame prediction coding with vector information. An error of a piece of divisional image information targeted for image prediction coding and a piece of predicted information is determined to perform prediction coding. A data stream in which a piece of information for identifying a prediction method and a piece of information subjected to prediction coding according to the method are arranged is produced according to the process sequence of the prediction coding for each process on the divisional image information. At this time, the data stream has a pair of vector information and the error information as information subjected to prediction coding for each process on the divisional image information on condition that the prediction method is intra-frame prediction coding with vectors.
