Subjective (Induced) Color Television

James F. Butterfield

A new color television system, which uses subjective (induced) color for the pickup, transmission and reproduction of color pictures with ordinary black-and-white TV equipment, is described. The system employs an optical device on the television camera which includes a filter-mask disc, that has three complementary filters (cyan, magenta and yellow) and an opaque sector. The disc is mounted in the optical path of a black-and-white TV camera between the lens and the pickup tube. A manual phasing control insures that the pickup tube's electronic beam scans behind the disc's webs which mechanically support the filters and opaque sectors. No electronic modification or additional equipment is necessary at the receiver. The induced color picture can be recorded in the normal manner on black-and-white video tape or film.
