IMAGE OBTAINING APPARATUS

摘要

An image obtaining apparatus has a swing-type optical system, an optical dome and a correction optical system. The swing-type optical system is configured to adjust a photographing direction based on a swinging operation. The correction optical system corrects transmitted light beams through the optical dome to parallel light beams parallel to the photographing direction.

1. An image obtaining apparatus comprising:
a swing-type optical system configured to adjust a photographing direction based on a swinging operation; an optical dome which covers the swing-type optical system and transmits through incident light beams; and a correction optical system, wherein the optical dome has a curved surface shape, wherein the curved surface shape is a curved surface shape that an angle between a light axis of the swing-type optical system and an imaginary perpendicular line to a surface of the optical dome differs in response to the photographing direction, the imaginary perpendicular line passes an intersection of the surface of the optical dome and the light axis of the swing-type optical system, wherein the incident light beams are parallel light beams parallel to the photographing direction, and wherein the correction optical system corrects transmitted light beams through the optical dome to parallel light beams parallel to the photographing direction.
