An extender lens includes an imaging lens having a 1× magnification and an imaging lens having a 2× magnification. For each of these imaging lenses, a master lens is adjusted in such a manner that the light-receiving surface of an image sensor will be brought to an in-focus position. The master lens adjustment processing is executed periodically and data indicating a history of amounts of adjustment of the master lens is stored in memory per imaging lens. Data indicating the history of amounts of adjustment of the master lens is read from the memory. Whether the television camera lens is malfunctioning is detected from the read data indicating the history. If a malfunction is detected, an error LED emits light to notify of the malfunction.

Abstract: A lens driving apparatus for a lens includes a voice coil motor. A coil position of a coil is detected. A table memory stores a correction factor for each one of plural values of the coil position according to flux density distribution. The correction factor is read from the table memory according to the detected coil position. A coil current is corrected by use of the correction factor for each coil position. The corrected coil current is caused to flow through the coil, with which the lens is moved together along an optical axis. Consequently, changes in a moving speed of the lens can be prevented.
