1. Process for driving an image sensing device having an image cell with a photo-sensitive element, a detection node and an output pin, comprising the steps of:

  • transferring charges accumulated during a first period of time from the photo-sensitive element to the detection node, thereby obtaining a first voltage;

    generating on the output pin a first value corresponding to the first voltage;

    transferring charges accumulated during a second period of time from the photo-sensitive element to the detection node, thereby obtaining a second voltage;

    generating on the output pin a second value corresponding to the second voltage.
