ABSTRACT:
An image processing apparatus includes: an image pickup section for converting an object light into image signals of Bayer RGB array; a color information detecting section for obtaining color information of the object from the image signals obtained by the image pickup section; a first luminance data generating section for finding luminance data for use in edge enhancement processing based on G signals of the image signals obtained by the image pickup section; a second luminance data generating section for finding luminance data for use in edge enhancement processing based on all color signals of the image signals; a selector for providing an output by switching between outputs of the first and second luminance data generating section; and a selection signal generating section for generating selection signal for controlling the switching of the selector based on color information obtained at the color information detecting section. The image processing apparatus is thereby achieved as capable of edge enhancement processing at favorable S/N and with less occurrence of edge noise in high saturation regions and low saturation regions.
