Patent ID: 7184085

Claim:
A charge multiplying solid-state electronic image sensing device comprising: a number of photoelectric transducers for storing signal charge in accordance with amount of incident light; a read-out device for reading out signal charge that has been stored in said photoelectric transducers; a charge multiplier for transferring the signal charge, which has been read out by said read-out device, while multiplying the electric charge; a converter for converting the signal charge, which has been transferred through said charge multiplier, to a video signal in accordance with a first conversion coefficient in response to setting of a first mode, and to a video signal in accordance with a second conversion coefficient, which is different from the first conversion coefficient, in response to setting of a second mode; and a calculation device for calculating amount of signal charge that has been stored in said photoelectric transducers based upon two video signals resulting from the conversion performed by said converter, the first conversion coefficient, the second conversion coefficient and number of multiplying stages of said charge multiplier.
