Claim 7:
8. An image capture apparatus comprising:
an image capturing element; and
an optical member control apparatus that comprises a first optical member and a second optical member that are arranged to be movable on the same plane that intersects an optical path of light that enters an image capturing element and that can be inserted into the optical path and can be retracted from the optical path, a drive unit capable of independently moving the first optical member and the second optical member, a position detection unit capable of detecting an insertion position and a retraction position of each of the first and second optical members, the insertion position of each optical member corresponding to a state where the optical member has been inserted into the optical path, the retraction position of each optical member corresponding to a state where the optical member has retracted from the optical path, and a control unit configured to control movement of the first optical member and the second optical member, wherein, when movement is performed to insert either one of the first optical member and the second optical member into the optical path and to retract the other of the first optical member and the second optical member from the optical path, the control unit performs control such that movement of the optical member that is to be inserted into the optical path is started after movement of the optical member that is to be retracted from the optical path is started and before the movement is complete, wherein, when movement is performed to insert either one of the first optical member and the second optical member into the optical path and to retract the other of the first optical member and the second optical member from the optical path, the control unit gives the drive unit a driving amount that is required to move the optical member that is to be retracted from the optical path to a predetermined position, and if it cannot be detected that the optical member has reached the predetermined position after a predetermined period of time has elapsed, the control unit performs retry control in which the control unit again gives the drive unit a driving amount that is required to move the optical member to the predetermined position.
