Abstract: A lens control device includes a processor that performs a control of generating image data for each of first wavelength range light and second wavelength range light by an image sensor, in which the processor estimates a first focus position of a focus lens for the first wavelength range light based on a first focus evaluation value determined in accordance with the image data of the first wavelength range light, estimates a second focus position of the focus lens for the first wavelength range light based on a second focus evaluation value determined in accordance with the image data of the second wavelength range light, and performs a control of moving the focus lens along an optical axis based on the first focus position in a case in which a comparison result obtained by comparing the first focus position with the second focus position satisfies a predetermined condition.

Abstract: Notification is given of the fact that a television camera lens has developed a malfunction. 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.
