Abstract
An image sensing device has an image cell with a photo-sensitive element, a detection node and an output pin. Charges accumulated during a first period of time are transferred from the photo-sensitive element to the detection node, thereby obtaining a first voltage, and kept on the detection node which is thus used as a memory. Some moments later, a first value corresponding to the first voltage is generated on the output pin, charges accumulated during a second period of time are transferred from the photo-sensitive element to the detection node, thereby obtaining a second voltage, and a second value is generated on the output pin corresponding to the second voltage. The signal thus generated is also proposed.
