Claim One:
1. An image processing apparatus, comprising: a first obtaining unit configured to obtain a feature amount indicating variance of signal values of pixels included in a region of image data, wherein the region is of a predetermined size and includes a pixel of interest; a second obtaining unit configured to obtain a feature amount indicating a brightness in the region; a determination unit configured to determine an amount of correction of a value of the pixel of interest using the feature amount indicating the brightness and an index value corresponding to the feature amount indicating variance in reference to index values corresponding to each of a plurality of mutually differing feature amounts indicating variance; and a correction unit configured to correct the value of the pixel of interest using the amount of correction determined by the determination unit, wherein the first obtaining unit, the second obtaining unit, the determination unit, and the correction unit are implemented by one or more processors or circuitry, or a combination thereof.
