Abstract
PURPOSE: To increase the accuracy of adjustment and to reduce the adjusting time, by detecting the amount of position shift on color for the grid pattern with the one dimension solidstate pick up element and automatically adjusting the dynamic convergence based on the detected value.
CONSTITUTION: The grid shape pattern of the pattern generator 13 is selected into sequentially red, green and blue pattern on the screen of CRT 12 with the R.G. B gun selection circuit 14 and pictured. In the one dimension solidstate pick up elements 11a∼11d, the signal in response to the light intensity caused by dark and light of the pattern and other parts, is generated and the signal having the peak value to the part corresponding to the pattern is detected, binarized 16 and fed to the position detection circuit 17, where the number of elements from the terminal reference element of the element 11 to the pattern terminal element is calculated. The operation control circuit 18 operates the calculated value and the operation constant of the memory circuit 19, determines the amount of adjustment and gives instruction to the pulse circuit 21. The position of the deflection yoke 20 is shifted and adjusted for the deflection yoke position control mechanism 22 with the output of the circuit 21 by the motor. Further, this is repeated.
