A multi-beam projector incorporates a cathode ray tube for each of the primary colors red, green and blue, with each cathode ray tube having two electron beams, with all of said electron beams being horizontally and vertically deflected in synchronism with each other. Primary color video signals are supplied to one cathode of each cathode ray tube for generating a first beam, and a delayed primary color video signal is supplied to the second cathode of each cathode ray tube for generating a second beam spaced from the first beam by a predetermined interval. The interval spacing between the beam of the cathode ray tube for the blue primary color is wider than the interval between the electron beams for the other cathode ray tubes. |
