Title:
IMAGING DEVICE
Document Type and Number:
Japanese Patent JP2015129829
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an imaging device that can suppress flickers of an image, which are generated when displaying an image acquired with changing the optical zoom magnification.SOLUTION: An imaging device of the present invention includes: an optical system capable of changing the optical magnification by moving a plurality of lenses in the optical axis direction; a diaphragm having an aperture for allowing subject light taken in by the optical system to pass therethrough, and capable of adjusting the amount of light of the subject light by changing the diameter of the aperture; a detection section for detecting the position of the optical system; an exposure calculation section for calculating the exposure conditions when acquiring an image; and a correction section for correcting the exposure conditions on the basis of the position of the optical system detected by the detection section and the diameter of the aperture adjusted by the diaphragm when the optical magnification of the optical system is changed in the process of continuously acquiring a plurality of images.
