ABSTRACT:
An image sensing apparatus of the type employing resolving and sensing means is provided with sensing means of selected size and geometry to allow approximation of arbitrary filter response. The sensing means of selected size and geometry may be incorporated into compact, self contained image resolving and sensing apparatus having a transparent substrate for resolving an incident image by refraction, diffraction or other suitable mechanism. The sensing means may be located directly on a surface of the transparent substrate. Logic and select circuitry may be integrally and simultaneously formed with the sensing means. The size and geometry of the sensing means may enable approximation to color inhibition and other effects to allow approximation of the spectral response of the human eye.
