摘要：
An image processing apparatus includes an input unit for inputting a plurality of color component signals, and a processing unit for executing processing for some color component signals of the plurality of color component signals, which processing is different from that for the remaining color component signals, in accordance with spatial frequency gain characteristics of the plurality of color component signals input by the input unit.
