Abstract: There is provided with an image processing apparatus. An acquisition unit acquires a first image captured with visible light and a second image captured with non-visible light. A correction unit corrects luminance of the second image so as to bring luminance distribution of the second image close to luminance distribution of the first image. A generation unit combines the second image whose luminance is corrected by the correction unit and chromaticity information of the first image to generate a composite image.
