ABSTRACT:
An image processing apparatus includes a determination part, an information obtaining part, a dynamic range setting part and a processing part. The determination part determines whether or not an image includes an area where destruction of gradation due to contrast correction tends to be conspicuous. The information obtaining part obtains information of the area when the determination part determines that the image includes such an area. The dynamic range setting part sets a dynamic range using the information obtained by the information obtaining part. The processing part performs the contrast correction on the image using the dynamic range set by the dynamic range setting part.
