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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Photodetector adapted to provide additional color information","description":"An apparatus for forming a color image of a scene and a method for utilizing that apparatus are disclosed.
