Head mounting type image display system
First Claim
1. A head mounting type image display system comprising:
- a head mounting type image display system main body having;
a) an image display element for displaying an image,b) an eyepiece optical system for guiding the image displayed on said image display element to an eyeball of an observer, andc) mounting means for allowing said image display element and said eyepiece optical system to be mounted on a head portion of the observer;
an operation device for displaying an input position indication mark on the image, and operating the input position indication mark; and
image conversion means for transmitting, to said image display element, an image signal in which a relative positional relationship between the image and the input position indication mark displayed on a display surface of said image display element has changed upon operation of said operation device,wherein the image signal converted by said image conversion means has a function of forming the input position indication mark to be movable within a circular range which has a radius not more than 1/4 a diagonal line length from an intersection of diagonal lines of the display surface and a function of scrolling the image as a background image with respect to the input position indication mark, both upon operation of said operation device.

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.

3. A head mounting type image display system comprising:
-
a head mounting type image display system main body having; a) an image display element for displaying an image, b) an eyepiece optical system for guiding the image displayed on said image display element to an eyeball of an observer, and c) mounting means for allowing said image display element and said eyepiece optical system to be mounted on a head portion of the observer; an operation device for displaying an input position indication mark on the image, and operating the input position indication mark; and image conversion means for transmitting, to said image display element, an image signal in which a relative positional relationship between the image and the input position indication mark displayed on a display surface of said image display element has changed upon operation of said operation device, wherein said operation device comprises; input position indication mark moving means for moving a display position of the input position indication mark with respect to the display surface in correspondence with an operation of the observer; and input position indication mark fixing means for fixing the input position indication mark at the display position of the input position indication mark which is changed by said input position indication mark moving means, and the image signal converted by said image conversion means has a function of forming the input position indication mark to be fixed in position within a circular range which has a radius not more than 1/4 a diagonal line length from the changed display position and a function of scrolling the image as a background image with respect to the input position indication mark, both upon operation of said operation device.
