Abstract

This video encoding device is provided with the following: a sample position shifting downsampler (107) that downsamples a luminance signal; and a predictor (101) that linearly predicts a chrominance signal from the downsampled luminance signal. The sample position shifting downsampler (107) shifts the positions of samples in the downsampled luminance signal in accordance with a scan for the signal being processed. This video decoding device is provided with the following: a sample position shifting downsampler (205) that downsamples a luminance signal; and a predictor (203) that linearly predicts a chrominance signal from the downsampled luminance signal. The sample position shifting downsampler (205) shifts the positions of samples in the downsampled luminance signal in accordance with the scan for the signal being processed.
