发明名称 View field frame position adjustable optical device
摘要 An optical apparatus that can take an image at any inclination. Further, the optical apparatus is provided with a function that a user can know the inclination. A visual field frame having the same shape as an imaging unit is provided in a lens-barrel such that the visual field frame can rotate, being interlocked with rotation of the imaging unit. Further, the optical apparatus is provided with a function of detecting rotation of the imaging unit itself interlocked with rotation of the visual field frame and rotation of the imaging unit caused by rotation of the lens-barrel at the time of adjusting the pupil distance or the like. At recording, an image is recorded in an inclined state adapted for the rotation of the imaging unit. As a result, even if the imaging unit is inclined contrary to the user's will at the time of adjusting the pupil distance, the imaging unit can be returned to be horizontal by rotating the visual field frame.
