Patent ID: 7706068

Claim:
An image three-dimensional recognition apparatus for making it possible for an observer existing at a particular distance away from the image three-dimensional recognition apparatus to recognize a planar image displayed in an image output device for displaying an image, as a three-dimensional image, comprising: a first mirror that has a width in a horizontal direction of not less than approximately 6.5 centimeter and not more than a distance from a right-eye-right-edge line connecting between a right eye of the observer and a right edge of the image output device to a left-eye-left-edge line connecting between a left eye of the observer and a left edge of the image output device; a second mirror that has a width in the horizontal direction of not less than the width in the horizontal direction of the first mirror; and a mirror fixing part for fixing the first mirror and the second mirror, wherein the second mirror is fixed to the mirror fixing part in such a manner that a second mirror plane, which is a mirror plane of the second mirror, is directed toward the planar image and is inclined obliquely downward, and the first mirror is fixed to the mirror fixing part in such a manner that a part or the whole of an image reflected in the second mirror plane is reflected in a first mirror plane, which is a mirror plane of the first mirror, and the first mirror plane is inclined obliquely upward.
