COLOR ENCODING SYSTEM UTILIZING TWO FILTERS ALTERNATELY FOR MINIMIZING EFFECTS OF IMAGE MISREGISTRATION AND IMAGE PICKUP DEVICE LAG

摘要

Apparatus is provided for enabling color images to be recorded on black and white motion picture film and subsequently displayed in full color on a television monitor. Different color-encoding filters yielding the same frequency color carrier waves having different phase relationships are moved into the optical path on alternate frames for producing color representative signals, which, when averaged over several horizontal scanning lines, reduce the undesirable effects of vidicon lag and frame-to-frame misregistration.
