Patent ID: 8730360

Claim:
An image sensing apparatus comprising: a solid-state electronic image sensing device having a number of optoelectronic transducers arrayed in horizontal and vertical directions, wherein color filters having filter characteristics for transmitting a light component of any color among the three primary colors red, green and blue or a light component of any color among the three complementary colors cyan, magenta and yellow, which are the complementary colors of the three primary colors, are formed on photoreceptor surfaces of the optoelectronic transducers; in one sub-block consisting of three of said optoelectronic transducers in each of the horizontal and vertical directions, a color filter having a filter characteristic for transmitting a green or yellow component is formed on the photoreceptor surface of an optoelectronic transducer in each row and in each column; this sub-block is repeated along the horizontal and vertical directions; of first and second sub-blocks adjacent in the horizontal and vertical directions, color filters having a filter characteristic for transmitting a blue or magenta component are formed on photoreceptor surfaces of said optoelectronic transducers at positions in said second sub-block that correspond to positions of said optoelectronic transducers on which color filters having a filter characteristic for transmitting a red or cyan component are formed in said first sub-block, and in the first and second sub-blocks adjacent in the horizontal and vertical directions, color filters having a filter characteristic for transmitting a red or cyan component are formed on photoreceptor surfaces of said optoelectronic transducers at positions in said second sub-block that correspond to positions of said optoelectronic transducers on which color filters having a filter characteristic for transmitting a blue or magenta component are formed in the first sub-block; signal charge that has accumulated in said optoelectronic transducers being output as a video signal; and a first video signal mixing circuit for mixing and outputting, from among video signals that are output from said solid-state electronic image sensing device, video signals obtained based upon signal charge that has accumulated in said optoelectronic transducers on which color filters having identical filter characteristics are formed, these video signals being weighted by such weighting coefficients that levels of the video signals after the mixing thereof will be equal for every color component.
