Abstract:
An image pickup apparatus includes a controlling unit moving an electronic front curtain in a simulated manner from an exposure start position towards an exposure end position by successively performing reset operations on a plurality of pixels in an image pickup element in a predetermined direction; a rear curtain that moves from the exposure start position towards the exposure end position by a biasing force of a biasing unit; and a storage unit storing data indicating a change in movement characteristics of the rear curtain with time. On the basis of the data, the controlling unit changes movement characteristics of the electronic front curtain in accordance with the change in the movement characteristics of the rear curtain with the time.
