Title:
LENS BARREL, IMAGING DEVICE, POSITION DETECTION METHOD, AND POSITION DETECTION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/022026
Kind Code:
A1
Abstract:
Provided are: a lens barrel that makes it possible to precisely detect the position of an object to be detected; an imaging device; a position detection method; and a position detection program. The lens barrel (200) is provided with: a first lens unit (220) provided with a position detection sensor configured from a hole sensor; and a second lens unit (240) provided with an electromagnetic actuator. When the relative positional relationship of the first lens unit (220) and the second lens unit (240) is changed by zooming, the output of the position detection sensor provided to the first lens unit (220) is corrected in accordance with the relative positional relationship of the first lens unit (220) and the second lens unit (240).
