More Information
Summary:An image processing apparatus, comprises: a detection unit configured to detect a predetermined region of an image from image data; and a correction unit configured to correct a value of luminance in the predetermined region detected by the detection unit. The correction unit corrects a high-frequency value out of a low-frequency value and the high-frequency value obtained from a luminance value of a pixel having a value of luminance higher than a predetermined threshold in the predetermined region so that a high-frequency contrast weakens.
