摘要： An apparatus for forming a color image of a scene and a method for utilizing that apparatus are disclosed. The apparatus includes a plurality of pixel sensors. Each pixel sensor includes a first photodetector includes first main photodiode and a first floating diffusion node. The first main photodiode is characterized by a first light conversion efficiency as a function of wavelength of a light signal incident thereon. The first floating diffusion node includes a parasitic photodiode characterized by a second light conversion efficiency as a function of the wavelength. The second light conversion efficiency is different from the first light conversion efficiency as a function of wavelength. A controller generates an intensity of light in each of a plurality of wavelength bands for the pixel sensor utilizing a measurement of the light signal by each of the first main photodiode and the first parasitic photodiode in that photodetector.
