IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM

摘要

In the present invention, a high-quality image in which glare due to high-luminance points is suppressed is acquired, while maintaining the impression of sharpness and resolution of the image as a whole. Provided is an image processing device (1) including: a high-luminance-pixel identifying unit (2) that identifies pixels having luminance values greater than or equal to a predetermined threshold in an input image; a frequency-distribution creating unit (3) that creates a frequency distribution of the luminance values of all 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) such that the frequency distribution created by the frequency-distribution creating unit (3) becomes closer to the target frequency distribution stored in the storage unit (4).
