摘要:
A high-quality image in which glare caused by high-luminance bright spots is suppressed is obtained, while maintaining the sense of sharpness and resolution of the image as a whole. Provided is an image processing apparatus (1) including a high-luminance-pixel identifying unit (2) that identifies pixels having luminance values equal to or greater than a prescribed threshold in an input image a frequency-distribution creating unit (3) that creates a frequency distribution of the luminance values of all of the pixels identified by the high-luminance-pixel identifying unit (2) a storage unit (4) that stores a target frequency distribution and a luminance correcting unit (5) that corrects the luminance values of the pixels identified by the high-luminance-pixel identifying unit (2) so that the frequency distribution created by the frequency-distribution creating unit (3) approaches the target frequency distribution stored in the storage unit (4).
