Correction of level difference between signals output from split read-out type image sensing apparatus

Abstract

Disclosed is an sensing apparatus using an image sensing device having at least first and second output terminals, comprising first and second amplifiers that independently amplify signals output from the first and second output terminals, respectively; a first gain controller that controls gain applied to the first amplifier; memory that stores data, which relates to gain to be applied to the second amplifier, that corresponds to respective ones of a plurality of different gains to be applied to the first amplifier; and a second gain controller that controls gain applied to the second amplifier in accordance with the data relating to gain to be applied to the second amplifier, obtained from the memory, corresponding to the gain applied to the first amplifier.

Dependencies are inferred from the claim text.
