Abstract
In an image sensing device, a photodiode is connected to a drain of a MOS transistor. The drain is connected to a gate of the MOS transistor via a resistor. The MOS transistor operates in a subthreshold region to output a signal being logarithmically proportional to the intensity of incident light to the photodiode.
