TRANSMITTING METHOD OF COLOR VIDEO PICTURE USING BLACK AND WHITE PICTURE CONTAINING COLOR INFORMATION

摘要

PURPOSE:To avoid the image shift in reproducing the color picture from black and white picture through one time of transmission, by transmitting the original of white picture recording chroma information, through color separation stripe filter. CONSTITUTION:Black and white picture of original picture including the chroma information recorded on a photographic paper 2 is scanned with a light source 4 and converted into the signal corresponding to the three primary colors with a photoelectric tube 5. This signal is input to a discharge tube 7 at the reception side via a transmission path 6 from the transmission side. The photo signal converted at the discharge tube 7 records the black and white image with chroma information according to the amplitude of photo signal on a photographic paper 9 which is sticked on a reception rotating drum 8.
