    摘要: A display apparatus includes a luminance change detecting unit for detecting change of luminance of a cathode ray tube, a deflection size control quantity adjusting unit connected to the luminance change detecting unit for stabilizing a deflection size by changing a deflection size correcting quantity at different rates of change for a low luminance range and a high luminance range, respectively, on the basis of the detected change of luminance. The deflection size control quantity adjusting unit generates a proper deflection size control quantity adjusting voltage by synthesizing a high frequency component and a low frequency component contained in a signal indicating the luminance change with different gains, respectively.
