Abstract
An image processing apparatus can correct the influence of contrast caused by a difference between a photopic vision and a scotopic vision to provide an image excellent in image quality. An averaged within-visual-field luminance calculation unit calculates a luminance value in the visual field based on at least one of environmental luminance in the visual field and luminance in a screen on which image data can be displayed. A reverse gamma conversion processing unit corrects the contrast of the image data based on the obtained luminance value in the visual field.
