Abstract
It is an object of the present invention to provide a solid-state imaging device for enhancing accuracy of AD conversion and active switching of up-counting and down-counting in the asynchronous counter without limiting the AD conversion frequency. The solid-state imaging device according to the present invention includes an asynchronous counter having an up-counting mode in which up-counting is performed, a down-counting mode in which down-counting is performed, and a holding mode for switching operation settings between the up-counting and the down-counting while maintaining a count value held in the asynchronous counter.
