  • Patent number: 5436661
    Abstract: A solid state image pick-up apparatus including an objective lens for forming an image of an object, and a color separation optical system for dividing said image of the object into four color images, e.g. first and second green images, a red image and a blue image, one of said four color images being right and left reversed, first to fourth solid state image sensors for receiving said four color images respectively to derive first and second green color signals, a red color signal and a blue color signal. Light receiving elements of said first solid state image sensor are shifted with respect to those of the second solid state image sensor by a half of a pitch at which these light receiving elements are arranged in a horizontal scanning direction to perform a so-called offset-site pick-up. The first and second green image signals are mixed with each other at an ideal ratio of 1:1 to derive a green color signal.

  • Patent number: 5184212
    Abstract: A circuit for producing a brightness signal from output color signals of a solid state image pick-up apparatus. The circuit comprises a delay circuit for delaying an output signal generated by one solid state image sensor by a delay time corresponding to one-half of a spatial sampling period so that the phase of the output signal of the one solid state image sensor is made to coincide with the phase of an output signal of another solid state image sensor. A first filter is provided for cutting off higher frequency components contained in the output signal of the delay circuit and in the output signal of the other solid state image sensor, and a signal processor is provided for processing output signals of the first filter.
