1. An imaging element having a plurality of pixels, wherein
the plurality of pixels have stored charge reset periodically,
at least in some of the plurality of pixels,
first readout processing in which stored charge by first exposure is read out is performed,
first signal processing based on a first pixel signal read out by the first readout processing is performed,
whether to perform second readout processing in which stored charge by second exposure is read out and second signal processing based on a second pixel signal read out by the second readout processing is determined, in response to a result of the first signal processing, and
the first readout processing, the first signal processing, and the second readout processing are performed within one cycle of reset which is performed periodically.
