摘要
[Subject(s)] To offer a ghost reducing device and an imaging device provided with it, a ghost reducing method, and an imaging optical system that can effectively reduce ghosts in a situation where ghosts can easily occur, and suppress deterioration in image quality in a situation where ghosts can hardly occur. [Means to Solve] A ghost reducing device includes multiple diaphragm blades that are formed in the vicinity of the pupil position in an imaging optical system and form at least one opening that lets light pass through, a diaphragm blade drive means that drives the diaphragm blades to adjust the size and/or position of the opening, and a control means that controls the driving of the diaphragm blades by the diaphragm blade drive means, wherein the control means controls the driving so that the diaphragm blades totally block the light in the symmetrical position to the opening with respect to the optical axis of the imaging optical system.
