PURPOSE:To simplify adjustment work, to stabilize quality and to shorten adjustment time by automatically adjusting multiple kinds of video input signals and writing adjustment data into RAM without a manual operation. CONSTITUTION:The luminance distribution of pattern size adjustment positions in plural places is detected by CCD cameras 21 installed in accordance with the plural adjustment positions for the scheduled types of the signals. An optimum deflection condition is automatically calculated from detected luminance distribution, and the optimum deflection conditions calculated for the respective scheduled input signals are automatically stored in RAM 12. |
