  • Imaging device with high dynamic range
    Patent number: 8742310
    Abstract: A high dynamic range imaging device including a first substrate with multiple pixels, each pixel having a photodetector associated with multiple read-out circuits. Each read-out circuit including a device for charging and discharging the photodetector that is associated with the read-out circuit. Each charging and discharging device being controlled by a charge and discharge activation signal imposing an integration time of the photodetector of each pixel associated with the read-out circuit. The device further including a second substrate, distinct from the first, with an electronic control circuit for controlling the charging and discharging devices, designed for generating multiple charge and discharge activation signals to be transmitted to the charging and discharging devices using electrical connections between the first and second substrates. Each pixel or group of pixels is associated to an activation signal imposing an integration time specific and appropriate to the pixel or group of pixels.
