Prediction-image generation device and prediction-image generation method

Abstract

[Problem] To obtain a prediction-image generation device capable of generating an intra prediction image in parallel processing while suppressing a circuit size. [Solution to Problem] A prediction-image generation device includes a storage means 1, a selection means 2, a prediction-pixel generation means 3, and a rearrangement buffer means 4. The storage means 1 holds a plurality of reference pixels. The selection means 2 selects, as a necessary reference pixel, a reference pixel used for generating an intra prediction image, based on a mode number and a pixel position. The prediction-pixel generation means 3 generates a plurality of prediction pixels in parallel processing, based on the necessary reference pixel. The rearrangement buffer means 4 generates the prediction image by rearranging the prediction pixels generated by the prediction-pixel generation means 3, based on a mode number.
