Abstract
A cathode ray tube non-sequential raster scanning method maintains a more uniform screen luminescence. This raster scanning method scans and stores electrical signals representing the locations of non-sequential blocks of adjacent raster lines or reordered individual raster lines from a cathode ray tube in a temporary storage apparatus. A programmable controller associated with the cathode ray tube and the temporary storage apparatus reorders the stored raster line location and selectively deflects the cathode ray beam. Analog or digital film-to-video transfer systems incorporating a cathode ray tube having non-sequential raster scanning are also described. A method of variable raster scanning for a weave correcting film-to-video transfer system is also disclosed.
