OPTICAL DEVICE, CONTROL METHOD THEREOF, IMAGING DEVICE AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a small and inexpensive optical system quickly switching a plurality of subject directions and subject images only by one optical device and available for both wide-angle and telescopic imaging. SOLUTION: A movable reflecting member is disposed in an imaging optical system having a plurality of objective lens groups for capturing subject light. An optional objective lens group for guiding the subject light to a pickup device can be selected from the plurality of objective lens groups by moving the reflecting member. At least one objective lens is formed of an optical system capturing a substantially 360°-subject image around an optical axis. COPYRIGHT: (C)2009,JPO&INPIT
