    摘要： An image coding apparatus which divides an input picture into a plurality of macroblocks and performs a prediction encoding for each macroblock, comprising a unit for calculating flatness based on pixel values contained in a macroblock of interest and determining whether the macroblock of interest is a flat macroblock, a unit for storing determination results for each macroblock, a unit for determining, based on the determination results, whether the macroblock of interest determined to be a flat macroblock belongs to a flat area, a unit for selecting one of the inter-prediction mode and the intra-prediction mode as a prediction mode for an encoding process of the macroblock of interest based on determination results and on cost values of the inter-prediction mode and the intra-prediction mode, and a unit for performing predictive coding according to the selected prediction mode.

    摘要： The present invention provides a functional block that executes video coding and video decoding based on H.264/AVC. The functional block includes two moving picture processing units, and a memory unit that stores therein data related to the results of processing of first plural macroblocks arranged within one row of one picture by the first moving picture processing unit. Data related to the results of processing of plural adjacent macroblocks, which are selected from the data stored in the memory unit, are transferred to the second moving picture processing unit. The second moving picture processing unit performs processing of one macroblock of second plural macroblocks arranged in the following row, using the transferred data.
