Abstract:
1. An image processing apparatus comprising: motion compensation circuitry that performs motion compensation using, as reference frames, a plurality of frames formed of images obtained by decoding encoded images and using motion vectors included in the encoded images, to generate a plurality of motion compensation images for generation of a prediction image from different reference frames, the generated prediction image being any one of a first prediction image, a second prediction image, and a third prediction image, wherein the motion compensation circuitry includes: prediction circuitry that generates the plurality of motion compensation images; first filtering circuitry that applies a low-pass filter to a difference image between the plurality of motion compensation images generated by the prediction circuitry; second filtering circuitry that applies a high-pass filter to an image obtained by the first filtering circuitry by the application of the low-pass filter; and prediction image generating circuitry that generates the first prediction image by adding the image obtained by the first filtering circuitry by the application of the low-pass filter and an image obtained by the second filtering circuitry by the application of the high-pass filter to one of the plurality of motion compensation images generated by the prediction circuitry.
