摘要 |
Scanning lines are automatically shifted by using a test signal for detecting a screen display height, a detector which detects information of the screen display height from the test signal, a calculator which calculates a scanning-line shift amount, a moire correcting waveform generator which generates a voltage for shifting the scanning lines, and a deflecting device which deflects electron beams.
