Color filter arrangement for optoelectric converting devices

Claim 1

A color filter arrangement for an optoelectric converting device, preferably a charge-coupled photoelectric device including a plurality of uniformily shaped photoelectric converting elements arranged side-by-side in a series and being sensitized to green, blue, green and red colors and by means of which a received optical image is converted into corresponding electric picture-point signals, the signals being processed in a video system in the predetermined order of green, blue, green and red picture-point signals, the filter arrangement comprising a transparent filter carrier superposed on said photoelectric converting elements; a plurality of color filtering elements arranged one after the other in said predetermined green, blue, green and red sequence on said carrier opposite the corresponding photoelectric converting elements; the surface area of said blue filtering elements being equal to or smaller than the surface area of the opposite blue-sensitive photoelectric converting elements; the surface areas of respective red and green filtering elements being smaller than the surface areas of the blue filtering elements in proportion to the difference in the spectral sensitivites of the photoelectric converting elements; and opaque masking means provided on said carrier, said masking means defining opaque webs between the consecutive filtering elements, the webs corresponding in width to the size differences between respective filtering elements and the assigned photoelectric converting elements.
