Patent ID: 7929026

Claim:
An image sensing apparatus comprising: an image sensing device; a focusing unit that focuses into an image on the image sensing device; an A/D converter that converts an image signal outputted by the image sensing device into a digital signal; a color interpolation unit that performs color interpolation on the digital signal converted by the A/D converter and generates image data on a plurality of color planes; a color space conversion unit that converts a color space of the plurality of color planes to a color space of another colorimetric system; a separation unit that separates image data in the color space of another colorimetric system into luminance data and hue data; an extraction unit that extracts a high frequency component from the luminance data separated by the separation unit; and a pseudo color removing unit that reduces a color component generated by the color interpolation unit, in accordance with the high frequency component of the luminance data extracted by the extraction unit and the hue data, wherein the pseudo color removing unit comprises: a determination unit that determines whether or not the high frequency component of the luminance data and the hue data fall within a color range of a pseudo color; and a unit that reduces a value of color difference data, determined to be within the color range of the pseudo color by the determination unit.
