Abstract
A CPU of a controller of an imaging apparatus includes a setting unit and a driving controller. The driving controller starts an exposure control in a case where an absolute value of a difference between a first target exposure value of a current frame and a second target exposure value of a previous frame is increased above a first threshold value. The setting unit acquires a second threshold value smaller than the first threshold value in accordance with the start of the exposure control. In a case where a magnitude relationship between the absolute value of the difference and the second threshold value satisfies a condition set in advance, the driving controller sets a threshold value to be compared with the absolute value of the difference to a third threshold value greater than the second threshold value and finishes the exposure control.
