The present technology relates to an image processing device and an image processing method which can enhance a prediction accuracy. When performing intra prediction using a matrix operation, a prediction image of a current prediction block that is subject to encoding and decoding is generated by interpolation processing in which an original pixel of a reference image is used as a top-adjacent pixel adjacent to the top of the prediction image of the current prediction block. The current prediction block is then encoded and decoded by using the prediction image. The present technology can be applied, for example, when encoding and decoding an image. 本技术涉及能够提高预测精度的图像处理装置和图像处理方法。当使用矩阵运算执行帧内预测时，通过使用参考图像的原始像素作为与进行编码和解码的当前预测块的预测图像的上方相邻的上方相邻像素的插值处理来生成当前预测块的预测图像。然后，通过使用预测图像对当前预测块进行编码和解码。本技术可以应用于例如对图像进行编码和解码的情况。
