An imaging device includes: an imaging section in which a plurality of pixels each having a photoelectric conversion element are arranged in a matrix shape; a clock generator that generates a plurality of phase signals having different phases; a reference signal generator that generates a reference signal which increases or decreases with a lapse of time; a comparator that is disposed to correspond to each column of an array of the plurality of pixels, performs a comparing process of comparing a pixel signal output from each pixel with the reference signal, and outputs a first comparison result signal and a second comparison result signal indicating a result of the comparing process; a latch section that is disposed to correspond to the comparator and latches logic states of the plurality of phase signals; and a latch controller.
