Abstract
There is provided an image processing apparatus. A calculation unit calculates a difference in a signal level, for each area, between a first image obtained by shooting a subject under a first shooting condition and a second image obtained by shooting the subject under a second shooting condition in which high-frequency components of an optical image of the subject are reduced compared to the first shooting condition. A mixing unit mixes a signal level of the first image and a signal level of the second image at a ratio based on the difference, so as to generate a third image. The mixing unit sets a ratio of the second image when the difference is a first value, to be larger than a ratio of the second image when the difference is a second value that is smaller than the first value.
