Abstract
In this hand-held color television viewing device, differently colored, side-by-side rasters are produced on the screen of a cathode ray tube from standard color television signals by the use of three pairs of serial delay lines. One delay line of each pair stores a horizontal scan line of color video information for a single color signal while the other delay line of each pair, each in succession, outputs the previously stored line in one-third of a line scan period to the control element of the cathode ray tube. The three side-by-side rasters are then optically combined into a single, composite colored, greatly enlarged, virtual image of high brightness.
