IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND STORAGE MEDIUM

摘要

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.

主权项

1. An image processing apparatus comprising:
an image acquisition unit configured to acquire image data; a brightness acquisition unit configured to acquire at least one of first brightness information relating to brightness of the image data and second brightness information relating to ambient brightness of a display area in which an image can be displayed based on the image data; a control unit configured to control contrast of the image data acquired by the image acquisition unit, based on the brightness information acquired by the brightness acquisition unit; and a display control unit configured to display an image based on the image data whose contrast has been controlled by the control unit.
