Image pickup apparatus

Abstract

The present invention relates to a compact and low-cost image pickup apparatus capable of photographing a high-quality image comparable to silver halide photographs, particularly an image in which color shift is inconspicuous. In the image pickup apparatus, an image of an object produced by an optical system 10 is formed on an electronic image pickup device 20, thereby obtaining image information concerning the object. The electronic image pickup device 20 and the optical system 10 satisfy the conditions: (1) 1.5<P<7.0; (2) 3.0<N<20; (3) 1.0×P<67 <5.0×P; and (4) nL/nT<0.25; where P is the pixel pitch (given in micrometers) of the image pickup device; N is the number of pixels (given in million) of the image pickup device; and θ is the angle (°) at which the central ray of a light beam exiting from the optical system or a ray passing through the center of a stop is incident on the image pickup device at the maximum image height.
