Patent ID: 6967686

Claim:
A storage medium storing a control program for controlling an image sensing apparatus comprising a zooming device adapted to perform zooming operation using a zoom lens, a focus adjustment device adapted to correct movement of a focal plane upon movement of said zoom lens by using a focus lens, a driving device adapted to independently move said zoom lens and said focus lens parallel to an optical axis, an image sensing element, a selection device adapted to select a charge storage time of said image sensing element, a shutter speed control device adapted to control a timing of the charge storage time of said image sensing element, and a control device adapted to control a focus speed of said focus adjustment device for compensating a change of the focal plane caused by the zooming operation and maintaining an in-focus state, wherein the control program has a control module for the step of controlling to change the focus speed of said focus adjustment device in accordance with a shutter speed so that the focus adjustment device can correct movement of the focal plane following the movement of said zoom lens during the zooming operation.
