Abstract
The present technology relates to an image processing device and an image processing method that enable simplification of processing. When matrix-based intra prediction that is intra prediction using a matrix operation is performed on a current prediction block to be encoded or decoded, matrix-based intra prediction is performed using a coefficient related to a sum of change amounts of pixel values and set to a fixed value, and a predicted image of the current prediction block is generated. Then, the current prediction block is encoded or decoded using the predicted image. The present technology can be applied, for example, in a case of encoding and decoding an image.
