Abstract
The present invention intends to provide a display position control apparatus which can prevent a position control signal to control a display position of an image from being unstable and can display the image with high image quality. A delay signal having a phase difference in a match state with reference to a vertical sync signal is generated. Whether a phase relation between the vertical sync signal and a horizontal sync signal is in a mismatch state is detected. When it is detected that the phase relation is in the mismatch state, a display position control signal is generated on the basis of the vertical sync signal and the delay signal. When it is not detected that the phase relation is in the mismatch state, the display position control signal is generated on the basis of the vertical sync signal and the horizontal sync signal.
