<P>PROBLEM TO BE SOLVED: To suppress an increase in device scale while reducing fixed pattern noise. <P>SOLUTION: A sensing device 10 includes a plurality of detection circuits P, a driving circuit 20, a plurality of holding parts 30, a plurality of amplification parts U, a control part 50, a line memory 46, and a differential circuit 48. In a first read period Te in each unit period T, a first signal generated in each amplification part U is supplied to the line memory 46. In a second read period Tf in each unit period T, a difference between a second signal generated in each amplification part U and the first signal read out from the line memory 46 is calculated. <P>COPYRIGHT: (C)2011,JPO&INPIT |
