Abstract:
1. An imaging device for picking up an image of an object via an optical system and recording image information in a recording medium, a driving system for the optical system being controlled according to a position of an operating unit, the imaging device comprising: a motor driving an object to be controlled by the driving system; a driver driving the motor; absolute position detecting means for detecting a relatively-low-resolution absolute position of the operating unit; relative position detecting means for detecting a relatively-high-resolution relative position of the operating unit; position generating means for generating a position output corresponding to a position in a restricted range of movement of the operating unit using a combination of the absolute position detected by the absolute position detecting means and the relative position detected by the relative position detecting means; control means for controlling the motor via the driver to drive the object to be controlled according to the generated position output of the operating unit.
