Abstract
An imaging apparatus includes a diaphragm unit configured to adjust an amount of incident light on an image sensor, a correction unit configured to perform a correction of an image signal that corresponds to driving of the diaphragm unit, and a control unit configured to control the diaphragm unit and the correction unit. The correction unit includes at least a first state for performing a correction of the image signal when it can be determined that the diaphragm unit is not being driven by the control unit and a second state for not performing a correction of the image signal or for performing a correction of the image signal weaker than that performed in the first state when it can be determined that the diaphragm unit is being driven by the control unit.
