Patent ID: 8508625

Claim:
An apparatus comprising: a generating unit configured to receive an image signal and generate a plurality of image signals in different frequency bands from the image signal; a synthesizing unit configured to synthesize the generated plurality of image signals with one another; a first signal generating unit configured to receive an image signal including a plurality of color signals including a first color signal and generate a first signal using image signals obtained by compensating for pixels which do not correspond to the first color signal; a second signal generating unit configured to receive an image signal including a plurality of color signals including the first color signal and generate a second signal using the plurality of color signals; and a mixing unit configured to receive an image signal including a plurality of color signals including the first color signal from the generating unit, determine a mixing ratio between the first and second signals based on the saturation of each pixel of the image signal, and generate a third signal by synthesizing the first and second signals with each other using the mixing ratio, wherein an image signal, among the plurality of image signals, which has a highest frequency band includes the third signal.
