Patent ID: 8742310

Claim:
A high dynamic range imaging device comprising on a first substrate to be exposed to light: multiple pixels, each pixel comprising a photodetector, and multiple read-out circuits associated with the multiple photodetectors, each read-out circuit comprising a device for charging and discharging at least one photodetector that is associated with this read-out circuit, each charging and discharging device being controlled by a charge and discharge activation signal (RST, TG) imposing an integration time of the photodetector of each pixel associated with the readout circuit, wherein it further comprises a second substrate, distinct from the first substrate, on which there is an electronic control circuit for controlling said charging and discharging devices, designed for generating multiple charge and discharge activation signals (RST, TG) to be transmitted to said charging and discharging devices by means of electrical connections between the first and second substrates, each pixel or group of pixels being associated to an activation signal imposing an integration time that is specific and appropriate to this pixel or group of pixels.
