Claim:
1. An imaging device comprising: a plurality of pixels, each of the plurality of pixels including a second transistor having an input for a reference signal, arranged at a ratio of one as to a plurality of the first transistors in the plurality of pixels, the second transistor and the first transistor in each of the plurality of pixels forming a differential pair which operates as a comparator in an analog-to-digital converter; a reference signal output unit configured to output the reference signal; and a fifth connecting transistor configured to connect a control node of the second transistor and a main node of the second transistor; wherein each of the plurality of pixels further includes a selecting unit configured to turn off the first transistor by applying a first voltage to a control node of the first transistor, and wherein the reference signal output unit is connected to the control node of the second transistor.
