Abstract
An image processing apparatus includes an input image color space conversion unit that converts an input image signal of each frame of a moving image signal into a luminance image signal and a color difference image signal, a luminance image correction unit that adjusts a histogram equalization correction intensity of a histogram equalization process for each frame and applies the histogram equalization process to the luminance image signal of each frame to generate a luminance-corrected image signal, a color difference image correction unit that applies a saturation enhancement process to the color difference image signal of each frame, in parallel with the histogram equalization process, to generate a color-difference-corrected image signal, and an output image color space conversion unit that converts the luminance-corrected image signal and the color-difference-corrected image signal into an output image signal in the same format as the input image signal.
