ABSTRACT:
In order to enhance resolving power and making the fabrication of an optical system easy, the image pickup device is of an arrangement that a color-separating optical means is disposed between an objective lens and a solid-state image sensor, and those images by the respective color lights which are focused at mutually displaced positions on the solid-state image sensor are integrated into one unified image by a signal processing circuitry to thereby collect also the image-informations corresponding to those areas lying between the picture elements. The color-separating optical means may be formed by either one of a color dispersion prism, a dichroic mirror, a diffraction grating, a glass block made of a medium of heterogeneous material and a light-divider containing liquid crystal.
