Abstract
A color detection active pixel sensor. The color detection active pixel sensor includes a substrate. A diode is electrically connected to a first doped region of the substrate. The diode conducts charge when the diode receives photons having a first range of wavelengths. The substrate includes a second doped region. The second doped region conducts charge when receiving photons having a second range of wavelengths. The photons having the second range of wavelengths passing through the diode substantially undetected by the diode. The substrate can include a doped well within the substrate. The doped well conducts charge when receiving photons having a third range of wavelengths. The photons having the third range of wavelengths pass through the diode substantially undetected by the diode.
