Document Type and Number:
WIPO Patent Application WO/2013/099606
Kind Code:
A1
Abstract:
The present invention relates to a configuration in which a plurality of zoom lens groups are driven by individual actuators for each of the zoom lens groups to perform a zooming operation. The present invention makes it possible to reduce the size of imaging devices, and makes it possible to perform macro photography. The present invention is provided with: a first zoom group actuator (115) for moving a first zoom group (105); a second zoom group actuator (117) for moving a second zoom group; a storage unit (133) for storing first positional information related to the first and second zoom group positions corresponding to the focal length regions at which a zooming operation is performed, and second positional information related to first and second zoom group positions different to the first positional information; and a controller (131) for controlling the first and second zoom group actuators (115, 117) on the basis of the first and second positional information to control the positions of the first and second zoom groups (105, 107).
