A system is disclosed for electronically processing negative composite video signals, wherein the negative composite video signals correspond to a negative image as produced by the projection of negative photographic film. The negative composite video signals are converted to positive composite video signals. The entire portion of the negative composite video signal between adjacent horizontal blanking portions is electronically inverted. The horizontal blanking portions of the negative composite video, which include the color burst signal, are not inverted. The composite signal that results includes the blanking portions, having the color burst signal, in their original, unaltered state. The image portion of the resulting composite signal, i.e., the portions of the resulting composite signal between the horizontal blanking portions, is inverted, and the resulting composite video signal is thus converted from negative to positive state.
