Title:
LENS DEVICE, IMAGING APPARATUS AND CAMERA SYSTEM
Document Type and Number:
Japanese Patent JP2019113630
Kind Code:
A
Abstract:
To provide a lens device, an imaging apparatus and a camera system, which suppresses occurrence of vignetting.SOLUTION: The lens device includes: an imaging optical system for forming an image circle of an image sensor 101; an image blur correction part for correcting an image blur; a shift drive part 220 for varying a relative positional relation between the image sensor 101 and the image circle; a tilt drive part 230 for varying an angle formed by an optical axis O and the normal line of the image sensor 101; a first drive detection part for detecting a drive direction and a drive amount of the imaging optical system by the shift drive part 220 and the tilt drive part 230; a second drive detection part for detecting a drivable range of the imaging optical system by the image blur correction part; and a lens-side control part for controlling the image blur correction part, the shift drive part 220 and the tilt drive part 230. The lens-side control part performs at least one of a first control for controlling the drivable range of the imaging optical system by the image blur correction part and a second control for controlling the drive of the shift drive part 220 and the tilt drive part 230.SELECTED DRAWING: Figure 1
