Abstract: An image correction device including: an image data acquisition part for acquiring the image data obtained by a camera; and a correction part for correcting the image data on the basis of a first difference that is a difference between a first image height obtained by light having entered the camera at a first incident angle and a first reference image height obtained by light having entered the camera at the first incident angle when the camera is free of manufacturing errors.

Abstract: A 3D adapter (100) comprises a left-eye optical system (OL) and a right-eye optical system (OR). The left-eye optical system (OL) is an optical system for forming a first optical image seen from a first viewpoint, and guides light from a subject to a uniaxial optical system (V). The right-eye optical system (OR) is an optical system for forming a second optical image seen from a second viewpoint that is different from the first viewpoint, and guides light from a subject to the uniaxial optical system (V).

Abstract: A light source provided with a laser element that emits a laser beam emits a laser beam for synchronization control. A synchronization mirror reflects the laser beam so as to allow a light receiving element in the light source to detect the laser beam. The synchronization mirror is provided on f-? lenses opposite to a light deflector, such that the f-? lenses are provided neither on a light beam path that connects the light source and the light deflector nor on a light beam path for synchronization control that connects the light deflector and the synchronization mirror.
