Patent attributes
An image observation system includes a pair of image observation devices for the left and right eyes of an observer. Each of the image observation devices includes an image pickup system which forms an image on a image pickup device using an image pickup optical system, and a display system which guides the light from the image acquired by the image pickup system to an observers eye by a display optical system. Each of the image observation devices is arranged so that the outside optical axis of the image pickup optical system is approximately aligned with an extension line of the eye-side optical axis of the display optical system. In the image observation system, the image pickup device included in the image pickup system of each image observation device is shifted horizontally by a predetermined distance relative to the optical axis of the image pickup optical system, and the display element is shifted horizontally by a predetermined distance relative to the optical axis of the display optical system. The optical axes of the image pickup optical systems and the optical axes of the display optical systems in the pair of image observation devices for the left and right eyes are parallel to each other.
