Classification: CPC H | IPC H

Claim 6:
7. The solid-state imaging element according to claim 1, wherein
the first and second reference voltages change over time with slopes different from each other,
the solid-state imaging element further includes
a first counter that receives the comparison result from the first comparator, counts a first period from a slope start of the first reference voltage to inversion of the comparison result received from the first comparator, and outputs a first digital signal in reference to a count value of the first period, and
a second counter that receives the comparison result from the second comparator, counts a second period from a slope start of the second reference voltage to the comparison result received from the second comparator, and outputs a second digital signal in reference to a count value of the second period, and

the first and second counters operate almost simultaneously.
