1. An imaging device comprising:
pixels;
a first analog-to-digital (AD) converter and a second AD converter, an analog signal read from each of the pixels being input into the first AD converter or the second AD converter, a digital signal corresponding to the analog signal being output from the first AD converter or the second AD converter into which the analog signal is input;
a first memory;
a second memory; and
a switching circuit connected between the first and second AD converters and the first and second memories, wherein:
the analog signal includes a reset signal representing a reset level or a pixel signal representing an image of a subject,
the first memory temporarily stores a first digital signal output from the first AD converter or the second AD converter, the first digital signal corresponding to the reset signal from one of the pixels,
the second memory temporarily stores a second digital signal output from the first AD converter or the second AD converter, the second digital signal corresponding to the pixel signal from the one of the pixels, and
the switching circuit selectively outputs the first digital signal to the first memory and the second digital signal to the second memory.
