PROBLEM TO BE SOLVED: To solve the problem in which: in an operation of an imaging device to which wiring supplying potential to comparators of a plurality of AD conversion units are commonly connected, the comparators of the plurality of AD conversion units may start operation simultaneously; and in this case, a change in a comparison result signal of a comparator causes potential variation of the wiring supplying potential to the plurality of comparators, which may result in a reduction in operation accuracy of other comparators.SOLUTION: Timings for a plurality of comparators to start operation are made different from each other, the plurality of comparators being applied with power source voltage through common wiring. |
