THREE-DIMENSIONAL COLOR IMAGE DISPLAY UNIT

摘要

PURPOSE:To stereographically display a color image by using a means which alternately extracts the color image signal with right and left parallax information and a horizontal deflection circuit which operates with a period 2 times that of the horizontal synchronous signal which is obtained from the color image signal. CONSTITUTION:Right and left eye color signals Sl and Sr with parallax information are selectively supplied to a cathode-ray tube through memory. The right and left image signals Sl and Sr are supplied to the fixed contacts 14a and 14b of a changeover switch 14 and the fixed contacts 15b and 15a of a changeover switch 15. The horizontal synchronous signal PH which is obtained from a horizontal synchronous signal separation circuit 16 is supplied to one input terminal of a phase comparator 17. The output signal from this phase comparator 17 is supplied as the control voltage of a clock generator 18 through a low pass filter 21. Further, the color image signal by which the right and left image signals Sl and Sr are switched alternately within the effective horizontal section and which generates N/2 right and left image picture elements, can be obtaind in the movable contact 14a of the changeover switch 14.
