Abstract

Image fusion is the generally preferred method to combine two or more images for visual display on a single screen. We demonstrate that perceptual image separation may be preferable over perceptual image fusion for the combined display of enhanced and synthetic imagery. In this context image separation refers to the simultaneous presentation of images on different depth planes of a single display. Image separation allows the user to recognize the source of the information that is displayed. This can be important because synthetic images are more liable to flaws. We have examined methods to optimize perceptual image separation. A true depth difference between enhanced and synthetic imagery works quite well. A standard stereoscopic display based on convergence is less suitable since the two images tend to interfere: the image behind is masked (occluded) by the image in front, which results in poor viewing comfort. This effect places 3D systems based on 3D glasses, as well as most autostereoscopic displays, at a serious disadvantage. A 3D display based on additive or subtractive transparency is acceptable: both the perceptual separation and the viewing comfort are good, but the color of objects depends on the color in the other depth layer(s). A combined additive and subtractive transparent display eliminates this disadvantage and is most suitable for the combined display of enhanced and synthetic imagery. We suggest that the development of such a display system is of a greater practical value than increasing the number of depth planes in autostereoscopic displays.
