An imaging apparatus includes an image sensor configured to capture an object image, a selection unit configured to automatically select a sensitivity of the image sensor from a predetermined selectable range, and an image processing unit configured to execute correction processing in which a signal of an image captured by the image sensor which has the sensitivity selected by the selection unit is amplified. When the image processing unit is set to execute the correction processing, the selection unit sets an upper limit of the selectable range lower, compared with the upper limit thereof when the image processing unit is not set to execute the correction processing.
