Abstract
A visual display system and method according to the present invention includes an inset image generator for producing video signals representative of a plurality of inset images and an inset image projection means for generating a plurality of inset images, each having a smaller size and a higher resolution than a background image, in response to the video signals. The inset image projection means includes an inset image projector having a number of video lines and dividing means for dividing the plurality of video lines into a number of subraster blocks, each of which can generate an inset image. Each subraster block is individually positioned by deflection means such that the high resolution of inset images can be individually positioned relative to the background image. In addition, the visual display system and method includes an inset image processor including allocation means for assigning the video signals representative of each individual inset image to an individual subraster block and, in some embodiments, assigning the video signals based upon a predetermined priority allocation criteria such that only predetermined ones of the inset images are displayed.
