Patent ID: 7542076

Claim:
An image sensing apparatus comprising: an image sensing device; a focusing unit configured to focus an image on said image on said image sensing device; an A/D converter configured to convert an image signal outputted by said image sensing device into a digital signal; a color interpolation unit configured to perform color interpolation on the digital signal converted by said A/D converter and generate image data on a plurality of color planes; a separation unit configured to separate the image data in the plurality of color planes into luminance data and color difference data; an extraction unit configured to extract a high frequency component from the luminance data separated by said separation unit; a pseudo color removing unit configured to reduce a color component generated by said color interpolation unit, in accordance with the high frequency component of the luminance data extracted by said extraction unit and hue data obtained from the color difference data; a determination unit configured to determine 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 reduction unit configured to reduce a value of the color difference data, determined to be within the color range by said determination unit.
