Abstract
It is possible to reduce an increase in entropy even if a reference pixel of a lower side or a right side is used in intra prediction. An encoding deviceaccording to the present invention includes: an intra predictorconfigured to generate a predicted image by using an intra prediction mode; a residual signal generatorconfigured to generate a residual signal from a difference between the predicted image and an original image; and an orthogonal transformerconfigured to, when the intra predictorgenerates the predicted image by using a reference pixel positioned on at least one of a right side and a lower side, perform orthogonal transformation processing on the residual signal after inverting a basis of at least one of a horizontal direction and a vertical direction.
