An image processing apparatus includes, a color correction unit performing color correction on RGB signals to generate color-corrected RGB signals; a YC conversion unit converting the color-corrected RGB signals into a first luminance signal and a color-difference signal; a Y conversion unit generating a second luminance signal based on the RGB signals; an edge combination unit combining the first luminance signal with the second luminance signal; an edge adjustment unit obtaining an edge-adjusted signal based on a result of the combining by the edge combination unit; and an adder adding the first luminance signal to the edge-adjusted signal.
