Abstract
Of three electron beams produced by an in-line type color cathode ray tube having a deflection device for producing uniform vertical and horizontal deflection fields, two beams are driven by G and B image signals that are delayed by CCDs in accordance with beam deflection positions on a fluorescent screen, so as to converge with the remaining one electron beam. A horizontal sync signal is also delayed by a CCD to remove a grid image deformation in accordance with the beam deflection positions. The amount of this delay is attained by reading out delay data stored in advance in a memory and supplying the delay data to a counter which are driven by horizontal and vertical deflection signals. An address decorder is provided to decode the contents of the counter to access the memory.
