Patent ID: 8824542

Claim:
An image processing apparatus comprising: processing circuitry including: an extraction circuitry portion that performs motion compensation using, as reference frames, frames formed of decoded images and using motion vectors in images that have been encoded, and that extracts motion compensation images having a lower resolution than a prediction image from the reference frames corresponding to the prediction image; and a prediction imaging circuitry portion that performs a filtering process to compensate the motion compensation images extracted by the extraction circuitry portion for high-frequency components by utilizing correlation in a time direction that is included in the motion compensation images, thereby generating the prediction image that has a higher resolution than the motion compensation images, wherein the prediction imaging circuitry portion includes a converter that converts a resolution of a difference image between a plurality of the motion compensation images extracted by the extraction circuitry portion and that increases the resolution of the difference image, a first filter that applies a low-pass filter to the difference image whose resolution has been increased by the converter, a second filter that applies a high-pass filter to an image obtained by applying the low-pass filter by the first filter, and an adder that adds the image obtained by applying the low-pass filter by the first filter and another image obtained by applying the high-pass filter by the second filter to one of the plurality of the motion compensation images extracted by the extraction circuitry portion, and that generates the prediction image.
