PROBLEM TO BE SOLVED: To obtain a sufficient definition correction effect for an object even when the object of high luminance and contrast is present in an image. SOLUTION: This definition corrector is composed of an area setting part 1 for dividing an input image into a specified area including an object and the other area without including the object, contour component extracting part 2 for extracting a contour component in the specified area, a contrast correction coefficient operating part 3 for operating the correction coefficient of contrast from the distribution of average luminance components in the specified area, a definition correcting part 4 for intensifying the contour component and correcting the luminance and the contrast and an output synthesizing part 5 for synthesizing an image in the specified area to which the definition correction is performed, with an image in the other area to which the definition correction is not performed and displayed the result. |
