Patent ID: 7567288

Claim:
An image pickup system comprising, at least: an image pickup optical system an electronic image pickup device having a complementary color filter comprising at least four color filter elements, said electronic image pickup device satisfying the following condition (41), and a controller for implementing signal process and image processing on the basis of an output from the electronic image pickup device, and a spectral strength curve for output signals that are produced from the electronic image pickup device upon incidence of light from the phototaking optical system thereon and photoelectric conversion of the light and correspond to at least one color filter (a curve delineated by the strength of an output signal at each wavelength when light is incident from a light source D65 on the phototaking optical system) satisfies the following condition (44): 1.0×10 −4 <p/d< 6.0×10 −4 (41) 0.45<( S 600 −S 650 )/ SP< 0.85 (44) where d is the diagonal length of an effective image pickup area, p is the center separation between horizontal pixels, Sp is the spectral strength peak, S 600 is the strength of 600 nm and S 650 is the strength of 650 nm.
