When dividing each frame that forms an encoding target video into a plurality of processing regions and subjecting each processing region to predictive encoding, the encoding is executed by subjecting a prediction residual signal to downsampling that utilizes an interpolation filter. The interpolation filter whose filter coefficients are not encoded is determined by adaptively generating or selecting, for each processing region, the interpolation filter with reference to information that is able to be referred to when corresponding decoding is performed. A low-resolution prediction residual is obtained by subjecting the prediction residual signal to downsampling that utilizes the interpolation filter.
