Abstract
PURPOSE:To obtain the unit easy for the adjusting operation, by obtaining the correction amount for other segments from the correction amount on the cross line passing through the screen center and the correction amount for the representative points at the four corners of screen and writing in it in the memory. CONSTITUTION:In case of initial adjustment requiring the correction for the entire screen, the adjustment for the representative adjusting points on the cross line passing through the screen center line is made. Next, the address is changed to the representative points of the right upper half corner of screen and the similar adjustment is made. To calculate the corrective amount of remaining segments from the corrective amount of the representative points, the operation start switch 28 of the corrective amount operation section 61 is placed at the operation mode and the operation is made as to the right upper half of the screen and the result is stored in the internal register. Next, the switch 28 is returned and the adjustment for other 1/4 screen is made, and further, the switch 28 is selected to the operation mode for 1/4 adjustment. When the correction of memory for the operation for the entire screen is finished, the switch 28 is returned to the normal mode and the switch 21 is taken as the readout mode.
