<p>IMAGING DEVICE AND METHOD FOR DRIVING AN OPTICAL SYSTEM An imaging device is arranged to pick up an image of an object via an optical system and to record image information on a recording medium. A driving system for the optical system is controlled according to a position of an operating unit. The driving system includes a motor driving an object to be controlled by the driving system, a driver driving the motor, an absolute position detector detecting a relatively-low-resolution absolute position of the operating unit, a relative position detector detecting a relatively-high-resolution relative position of the operating unit, a position generator, and a controller. The position generator generates a position output corresponding to a position in a restricted range of movement of the operating unit using a combination of the detected absolute position and the detected relative position. The controller controls the motor via the driver to drive the object to be controlled according to the generated position output of the operating unit.</p> |
