Title: Color photographing apparatus
Inventor: DAKANASHI ITZUO
IPC: H04N9/07
Filed: 1985-09-28
Granted: 1990-05-12
Abstract: An optical image is focussed on a photoelectric conversion target (6) of a colour image pick up tube. This occurs through a colour stripe filter (4) having a number of successively arranged recurrent groups of different colour stripes. An electrostatic image is produced which is scanned in rectangular raster form by an electron beam to generate a luminance signal and a colour multiplexed video signal. A circuit detects leading and trailing edges of the luminance signal and generates a control signal having two polarities in response to the leading and trailing edges, respectively. A circuit times the colour multiplexed signal with the luminance signal in accordance with the control signal. The edge detector may have a circuit (21) delaying the luminance signal. A differential amplifier (20) receives the delayed and non-delayed luminance signal.
