Abstract
Apparatus for use in sequential color imagery wherein three successive monochrome images are acquired by a video system and then displayed simultaneously upon a screen as a color picture. A flash lamp is used to sequentially illuminate a target through a color wheel and thus create three primary color separated images which are recorded in series by the video camera. The intensity of each image is controlled by varying the output of the lamp during each imaging sequence to balance the primary colors used to recreate an original target upon the television screen so that the video picture accurately duplicates the colors found in the original.
