ABSTRACT:
A solid-state image sensing apparatus comprises a charge coupled device, a plurality of photosensors, and a voltage generator. Each of the photosensors receives incident light, generates a voltage logarithmically proportional to an intensity of the incident light, and is connected to a first electrode of the charge coupled device. The voltage generator generates a reference voltage logarithmically proportional to an average intensity of the incident light on the photosensors and is connected to a second electrode of the charge coupled device. Signal charges are injected into the charge coupled device, depending on the voltage impressed on the first and second electrodes, so that a direct current component of an output of the charge coupled device is controlled.
