The image sensing apparatus and an imaging system

The present invention discloses an image sensing apparatus and an imaging system. An image sensing apparatus comprising: a first transfer block transmitting unit and a second transfer unit, wherein the first transfer unit includes transmitting a first signal to the output unit of the first impedance converter, a first impedance of the first transmission unit a first offset between a signal obtained by superimposing the first offset on the first signal and the differential signal is transmitted as a third transducer signal, the second transfer unit includes a first transmitting a second signal to the output unit of the two impedance transformer, and a second transmission unit a second offset of the second impedance converter and a differential signal between a signal obtained by superimposing the second offset on the second signal is transmitted as the output of the fourth signal means calculates the difference between the third signal and the fourth signal, generating and outputting image signals.
