Abstract:
A photographic lens drive control apparatus according to the present invention includes a cap detection section which determines that a lens cap is attached to a lens barrel when a lens barrel movement detection section does not detect movement amount of the lens barrel while a lens barrel drive section allows the lens barrel to move from a contained position to a standby position; and a cap detection control section which performs a series of control over the lens barrel drive section to move the lens barrel from the contained position to the standby position and to stop the lens barrel from moving when the cap detection section determines that the lens cap is attached to the lens barrel, in which a cap detection area where the lens barrel moves from the contained position within a predetermined amount is set in a movement area of the lens barrel.
