Problems solved by technology

However, since images viewed at different angles are simultaneously acquired, the optical or mechanical structure of a device for capturing 3D images is more complex than that of a device for capturing 2D images
In addition, capturing 2D images requires an additional camera since 2D images cannot be obtained by utilizing the device used to capture 3D images

Abstract

A light quantity adjustment apparatus comprises a support plate comprising a first through hole through which light passes; a rotation plate comprising a second through hole corresponding to the first through hole and rotatably disposed with respect to the support plate; a plurality of 2D iris plates rotatably connected to the support plate so as to move between an open location in which the first through hole is completely opened and a closed location in which the first through hole is completely closed, the plurality of 2D iris plates engaged with the rotation plate and adjusting an open area of the first through hole according to a rotation of the rotation plate; two 3D iris plates each having one end rotatably connected to the support plate and another end engaged with the rotation plate, the two 3D iris plates moving between a retreat location away from the first through hole according to the rotation of the rotation plate and a photographing location where a first photographing hole and a second photographing hole are formed by covering a part of the first through hole; a shading plate that moves between an operating location where the first photographing hole or the second photographing hole is closed and a stop location away from the first through hole; and a shading plate driving unit that drives the shading plate.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2010-0088051 filed with the Korean Intellectual Property Office on Sep. 8, 2010, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to a light amount adjusting device, and more particularly, to a light amount adjusting device for a photographing device capable of selectively capturing a 3D image or a 2D image, and a photographing device having the light amount adjusting device. Background technique [0003] The 3D image provides a stereoscopic effect to a visually observed object (subject). Although 3D images are only used in medical equipment, many videos are produced using 3D images, and 3D TV technology is developing rapidly. [0004] To provide a 3D image, images captured at different angles according to human eyes are simultaneously provided, and thus, an apparatus for capturing a 3D image has a different operati...
