Patent ID: 7423677

Claim:
An apparatus that eliminates red, green, or blue filters for generating signals representing red, green, and blue components of an input light signal, the apparatus comprising: a first sensor configured to receive the input light signal and generate therefrom a V_clear voltage corresponding to the input light signal; a cyan color filter configured to receive the input light signal and propagate therethrough, a cyan light component of the input light signal; a second sensor coupled to the cyan color filter and configured to generate from the cyan light component, a V_cyan voltage corresponding to the cyan light component; a magenta color filter configured to receive the input light signal and propagate therethrough, a magenta light component of the input light signal; a third sensor coupled to the magenta color filter and configured to generate from the magenta light component, a V_magenta voltage corresponding to the magenta light component; a yellow color filter configured to receive the input light signal and propagate therethrough, a yellow light component of the input light signal; a fourth sensor coupled to the yellow color filter and configured to generate from the yellow light component, a V_yellow voltage corresponding to the yellow light component; and a desired color signal generation mechanism (DCSGM) configured to receive the V_clear, V_cyan, V_magenta, and V_yellow voltages and generate therefrom, a V_red voltage, a V_green voltage, and a V_blue voltage, the generation comprising at least one of a) a first mathematical operation defined by V_red=V_clear−MF 1 (V_cyan) where MF 1 is a first multiplication factor having a value of about 1.2, or b) a second mathematical operation defined by V_red=MF 2 (V_clear)−V_cyan where MF 2 is a second multiplication factor having a value of about 0.8.
