Abstract
There is no risk of generating unnecessary events. This imaging device comprises: a photoelectric conversion unit that has a plurality of photoelectric conversion elements for performing photoelectric conversion to generate an electric signal; a setting unit that sets a threshold value according to a noise level in a predetermined region among the plurality of photoelectric conversion elements; and a first detection unit that detects a detection signal in a case where the amount of change in the electric signal generated by the plurality of photoelectric conversion elements exceeds the threshold value.
