Abstract:
An image display system comprising:image taking means for producing a plurality of image signals corresponding to a plurality of optical images from different view points; control signal outputting means for outputting control signals indicating controlled states of said image taking means while said image taking means is taking said optical images, in order to produce said image signals; display image signal generating means for generating a first display image signal and a second display image signal based on said image signals; display means for enabling an observer to observe an enlarged virtual image of a first display image based on said first display image signal with one of the eyes of said observer and enabling said observer to observe an enlarged virtual image of a second display image based on said second display image signal with the other one of the eyes of said observer, wherein said display means have a first display device for displaying said first display image based on said first display image signal, a second display device for displaying said second display image based on said second display image signal, a first optical system for enabling said observer to observe said enlarged virtual image of said first display image displayed in said first display device with said one of the eyes of said observer and a second optical system for enabling said observer to observe said enlarged virtual image of said second display image displayed in said second display device with said other one of the eyes of said observer; and controlling means for controlling a displaying state of said display means based on said control signals outputted from said control signal outputting means, while said display means is enabling said observer to observe said enlarged virtual image of said first display image with said one of the eyes of said observer and said enlarged virtual image of said second display image with said other one of the eyes of said observer, wherein said controlling means change a spatially relative position between said enlarged virtual image of said first display image and said enlarged virtual image of said second display image on the basis of said control signals in order to change a convergence angle between an optical axis of an eye of said observer observing said enlarged virtual image of said first display image and an optical axis of the other eye of said observer observing said enlarged virtual image of said second display.
