Abstract
A lens device includes: a movable lens that is movable in a direction of an optical axis; an operation signal acquisition section that acquires an operation signal corresponding to an amount of movement of an operation member which is movable; a smoothing processing section that smooths the operation signal; and a movable lens driving section that drives the movable lens based on the smoothed operation signal.
Claims20
A lens device comprising:
- a movable lens that is movable in a direction of an optical axis and comprises a focus lens;
- a processor, configured to:
- acquire an operation signal corresponding to an amount of movement of an operation member which is movable;
