US Patent 7907834 Image processing apparatus and image processing method

An image processing apparatus includes a reception unit, a decoding unit, a sub frame generating unit and an image signal generating unit. The reception unit receives at least three encoded image data via a serial bus. The decoding unit decodes one of the received encoded image data to generate a main frame. The sub frame generating unit extracts low frequency component from each one of the other received encoded image data, and generates sub frames from the extracted low frequency components. The image signal generating unit combines the main frame and the sub frames, and generates an image signal including the main frame combined with the sub frames.
