The present disclosure relates to an image processing apparatus and a method therefor capable of reducing the amount of memory required for intra-frame prediction.
The apparatus includes: a sampling unit that performs sampling to thin out pixel values to be used as adjacent pixels in intra-frame prediction according to a size in an horizontal direction of an image to be coded or a size in a vertical direction of regions obtained by dividing the image; a reconstruction unit that performs interpolation by using the pixel values sampled by the sampling unit to reconstruct the adjacent pixels; a predicted image generation unit that performs the intra-frame prediction by using the adjacent pixels reconstructed by the reconstruction unit to generate a predicted image; and a coding unit that codes the image by using the predicted image generated by the predicted image generation unit. The present technology can be applied to an image processing apparatus, for example.
