Image display system for displaying an adjustable widened virtual image

An image display apparatus with a display device for displaying images and a viewing device for viewing an image in the left eye and a different image in the right eye. Two smaller images, a left image and a right image, are created from the same two-dimensional image. The left image includes, as it's left most part, the left most part of the two-dimensional image, the right image includes, as it's right most, the right most part of the image two-dimensional image, and both the left and right images include a common central part of the full image. When the left and right images are displayed such that the left eye sees one image and the right eye sees the other image, the viewer sees the two-dimensional image as a virtual image that can be wider than the viewable width of the display device. The width of the virtual image can be varied to accommodate the viewer.
