Abstract
An image processing apparatus comprises: first and generation units that generate color signal components for luminance and color signal components for color difference, respectively, in a first color space from an input image signal; an integration unit that integrates the color signal components for luminance and color difference to generate color signal components common for luminance and color difference; a processing unit that performs nonlinear processing on the color signal components common for luminance and color difference; a separation unit that generates luminance and color difference signals in a second color space from the signal that has undergone the nonlinear processing; and a band limiting unit that performs band limitation processing on the color difference signals. A characteristic of the band limitation processing is set on the basis of frequency characteristics of the luminance color difference signals.
