Classification: CPC H | IPC H

Claim 13:
14. The solid-state image sensor according to claim 13, wherein
the predetermined voltage is a variable voltage that varies to either the upper limit voltage or the lower limit voltage different from each other,
the comparison result processing unit includes
an upper limit-side comparison result processing unit that processes the voltage comparison result corresponding to the upper limit voltage, and
a lower limit-side comparison result processing unit that processes the voltage comparison result corresponding to the lower limit voltage, and
the count unit further includes
an upper limit-side switch that opens or closes a path between the voltage comparison unit and the upper limit-side comparison result processing unit according to a polarity signal indicating a value of the variable voltage, and
a lower limit-side switch that opens or closes a path between the voltage comparison unit and the lower limit-side comparison result processing unit according to the polarity signal.
