ABSTRACT:
An underwater scene is viewed by a TV camera which in place of the conventional blue, green and red filters has three filters with transmission characteristics within the range of colors passed by the water medium, typical filters being blue-green, green, and yellow-green. The three TV signals from these signals are used to energize the conventional blue, green and red guns of a color TV cathode ray tube (CRT).
