ABSTRACT:
A method and system for generating a bordered split screen video display. In preferred embodiment, the invention generates a composite signal from digital signals representing reference and scanned film images, converts the composite signal to a composite video signal, and displays the composite video signal as a bordered split screen video display. The invention can be embodied in a film scanning system which includes a processor for digitally correcting a digital signal representing a digitized film image, such as by performing digital color correction on the digital signal. The film scanning system also includes field store circuitry for storing the corrected digital signal and a digital reference signal, circuitry for generating a composite signal from the stored reference and corrected signal, and circuitry for generating a composite video signal from the composite signal. In accordance with the invention, the composite video signal is displayed as a split screen composite image having a distinctive border between distinct test and reference picture areas. In a class of preferred embodiments, a graphics cursor signal is also inserted into the composite signal. When displayed, the cursor signal overlays a cursor region of the bordered split screen composite image.
