ABSTRACT:
According to one embodiment, a moving picture coding device which performs a motion-compensated prediction for moving picture data in macroblocks, applies discrete cosine transform and quantization to a prediction error obtained by the motion-compensation prediction to obtain a quantization coefficient, and applies variable-length-coding to the quantization coefficient together with a motion vector to be obtained by the motion-compensation prediction, when controlling each coding mode of target macroblocks for the variable-length-coding in response to a picture type, the coding device determines whether the quantization coefficient is not smaller than a threshold if the picture type is a B, performs motion detection processing only by frame prediction if the quantization coefficient is not smaller than the threshold, performs the motion detection processing after conventional frame/field prediction determination if the quantization coefficient is smaller than the threshold, and skips coding processing of the target macroblocks under prescribed conditions after motion detection processing.
