ABSTRACT:
Mounted on the head of an observer, an image display element has an eyepiece optical system which guides the displayed image onto the eyeballs of an observer. An input position indication mark is displayed on the image. An image converter transmits an image signal to the image display element with the relative positional relationship between the image and the position indication mark changed. The converted image signal forms the input position indication mark so that it is movable within a range which has a radius of 1/4 or less of a diagonal line length extending from the intersection between the diagonal lines of the display surface. The image scrolls as a background image with respect to the position indication mark.
