An imaging apparatus includes: a controller that performs first synchronization control of outputting a first synchronization signal at a first timing after receiving an instruction of continuous imaging, outputting a second synchronization signal at a second timing after elapse of a first time period from the first timing, and outputting the second synchronization signal every time a second time period longer than the first time period elapses after the second timing; and an imaging unit that starts reading of a signal from an imaging element by a rolling shutter method at a third timing at which an input of the second synchronization signal is received after the second timing, and starts exposure of the imaging element by the rolling shutter method at a fourth timing before the third timing so that an interval between the fourth and third timings is equal to a length of an exposure time period.
