摘要： An image coding apparatus executes intra-frame prediction with a predetermined intra-frame prediction mode for a certain block. A block selection unit judges that the current block to be coded is a prediction error calculation block or a non-prediction error calculation block. In the case where the current block is a prediction error calculation block, a mode error value calculation unit calculates the prediction error by the sum of absolute differences and for all of the intra-frame prediction modes, an inter-mode comparison unit compares the prediction errors, and as a result of the comparison, an intra-frame prediction mode having the minimum prediction errors is determined as the intra-frame prediction mode. In the case where the current block is a non-prediction error calculation block, the prediction error is not calculated. As an alternative, a prediction mode estimation unit determines the intra-frame prediction mode based on the neighboring prediction mode information stored in a storage unit.

摘要： The present invention provides a video encoding device in which a capacity of a binary data storing unit is small, a size of the video encoding device is small, a video signal can be processed in real time, and reduction in quality of images generated from the eventually obtained data can be prevented. The video encoding device according to the present invention includes: a video encoding unit which encodes a video signal; a binarization unit which binarizes an encoded value obtained from the video encoding unit; and an entropy encoding unit which subjects entropy encoding to binary data obtained from the binarization unit.
