IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND CAMERA SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an image processing apparatus and image processing method which can adaptively perform contour correction for an arbitrary luminance and can perform sufficient contour enhancement for a desired portion of image data, and also to provide a camera system.

SOLUTION: The image processing apparatus 200 includes: a contour correcting portion 210 for correcting a contour signal of an input digital image signal; a non-linear luminance generating portion 220 for performing gamma correction on a digital image signal to generate a luminance signal; and a contour correction adding portion 230 for adding a final contour image signal S210 output from the contour correcting portion 210 to the non-linear luminance signal S220 generated by the non-linear luminance generating portion 220. The contour correcting portion 210 includes a gain generating portion 213 which is inputted with the luminance signal of digital image and generates a contour correction gain according to the luminance, and has a function to perform luminance modulation correction on the contour signal using the generated gain.
