Semiconductor system for registration of spectra, colour signals, colour images etc., has adjustable colour filters in front of each pixel

摘要

The system comprises a CCD- or CMOS chip (1) with several light-sensitive pixels (2) in front of each of which a colour filter (3) is provided. The colour filters are adjustable by changing a voltage. All colour filters may be synchronously set to the same wavelength range, which is continuously variable. The filters may be synchronously set to the colors red, blue, and green.
