Abstract
An electronic image pickup apparatus comprising an imaging optical system for forming images of an object and image pickup device having light receiving surface configured so as to sample the images at discontinuously distributed points. This image pickup apparatus functions to sample the images of the object formed by the imaging optical system while receiving the images on the light receiving surface of the image pickup device and output signals representing light intensities on the object side. Disposed in the imaging optical system is a refracting surface which produces the optical low pass effect and has a shape capable of exhibiting an effect to eliminate moire, for example, due to a fact that it includes a point on which differential coefficients of a function expressing a shape of the refracting surface are discontinuous.
