The present invention relates to a method for reducing image instability in a virtual environment due to the transport delay of the image generator and other components of the system. A method is given for determining the error in the generated virtual environment and using this error for shifting the image on the display device thus providing a more accurate and more stable representation to the viewer.

For displaying moving images on a head mounted, temporal modulation display device from a video source, without image break-up appearing in the observed image, an image shift device is provided for shifting each temporally separated component image within each display cycle of grey scale component images representing each frame of the video source. The display device is for use with head mounted displays in which an LCD or other FPD using temporal modulation is used to display video images without image break-up during head motion.

For displaying moving images on a field sequential color display device from a simultaneous color image source, without color break-up appearing in the observed image, an image shift device is provided for shifting each color component image within each cycle of color component images representing each frame of the simultaneous color video image source. The display device is for use with head mounted displays in which an LCD or a CRT screen is used to display field sequential color images without color break-up during head motion.
