PURPOSE:To precisely perform the cross talk adjustment of a deflection yoke by allowing a subject deflection yoke to directly extract vertical and horizontal straight line patterns and measuring the inclination of patterns to align them to cross at right angles. CONSTITUTION:The color drift of three primary color patterns is measured by scanning vertical pattern R, G, B measurement positions of three primary colors with a black-and-white ITV camera 6 and measuring scanning times tRm, tGm, tBm, from a horizontal synchronous signal to individual vertical patterns of camera detection waveforms (video outputs) obtained. For horizontal patterns, the color drift can be also measured by vertically scanning with the black-and-white ITV camera, for example. The positional adjustment of H patterns and V patterns on a TV screen is performed after measuring the effect due to mutual induction in advance. |
