    Photoelectric effect; Photoelectric effect

    The process by which a photon of light, incident on a specific material, releases an electron that participates in the conduction current. The photon's energy is totally or partially transformed into kinetic energy.

    Pixel; Pixel

    The smallest light-sensitive element in an image (contraction of picture element). A sensor's pixels can be either contiguous or spaced apart; their size (1.5 µm to 30 µm) and shape are optimized to suit the intended application.

    Capacité à puits plein ; Full well capacity

    Maximum number of electrons that can be trapped by the potential difference that maintains the pixel's potential well. It is expressed in number of electrons, in bits or in grayscale/color.
