Enhancing the resolution of monoscopic images on stereoscopic displays

Where monoscopic images (e.g. blocks of text) are reproduced on stereoscopic displays, the resolution can be increased for the viewer as follows: it is necessary to start with an image with double the quantity of lines and columns as that of the stereo displays. Offset sub-rasters are derived from this and output on the displays for the left and right eye. Inter-pixel information is produced in this way, which is combined in the brain to form a higher resolution than that of an individual display. This fusion is effected by means of disparity compensation in the visual cortex. This image combination corresponds to a superresolution with two images, as a result of which image sharpness improves and image noise is reduced. Moreover, further raster separations are presented with which horizontal or vertical image structures are preferentially emphasized or displayed with greater sharpness, for example for overlaying lettering.
