DETAILED DESCRIPTION It is an object of the present invention to provide an image display apparatus and an image input apparatus, which can improve observability by setting different display conditions of images to be presented to the right and left eyes of an observer.
In order to achieve the above object, according to one aspect of the present invention, there is provided a stereoscopic image display apparatus which allows an observer to recognize a stereoscopic image, comprising: right eye image display means for displaying an image for a right eye by irradiating light; left eye image display means for displaying an image for a left eye by irradiating light; and tilt means for tilting a central line, in a vertical direction, of an observation image which is formed based on the image for the right eye and is to be observed by the right eye of the observer, and a central line, in the vertical direction, of an observation image which is formed based on the image for the left eye and is to be observed by the left eye of the observer, relative to each other within a range from an angle larger than 0.
degree.
to an angle not more than 3.
degree.
.
According to a preferred aspect, the tilt means comprises means for rotating at least one of the right and left eye image display means in a display surface of the image display means.
According to a preferred aspect, the tilt means comprises an image rotator arranged in an optical path of at least one of the right and left eye image display means.
According to a preferred aspect, the tilt means comprises means for rotating a display image of at least one of the right and left eye image display means by coordinate conversion processing, and displaying the rotated image on the image display means.
According to a preferred aspect, the tilt means comprises one of means for rotating clockwise the central line, in the vertical direction, of the observation image to be observed by the right eye of the observer and means for rotating counterclockwise the central line, in the vertical direction, of the observation image to be observed by the left eye of the observer
