Patent ID: 7362358

Claim:
An image sensing apparatus using an image sensing device having at least first and second output terminals, comprising: first and second amplifiers that independently amplify signals that are output from the first and second output terminals, respectively; a first gain controller that controls gain applied to said first amplifier; memory that stores data, which relates to gain to be applied to said second amplifier, that corresponds to respective ones of a plurality of different gains to be applied to said first amplifier; and a second gain controller that controls gain applied to said second amplifier in accordance with the data relating to gain to be applied to said second amplifier, obtained from said memory, corresponding to the gain applied to said first amplifier; wherein the data relating to gain stored in said memory is obtained by first supplying same gain to both said first and second amplifiers, and obtaining a level ratio of signals from said first and second amplifiers at each gain with regard to a plurality of different gains.
