Patent ID: 7145579

Claim:
A display apparatus comprising: a plurality of delay means having variable delay amounts that delay each of a plurality of color signals; phase detection means that detects each phase in the plurality of color signals relative to a reference signal; calculation means that, based on a detection result by the detection means, determines which color signal from the plurality of color signals is delayed the most relative to the reference signal, and determines phase differences of other color signals relative to this color signal; and control means that controls a delay amount of a delay means of the color signal that is delayed the most such that the delay amount is a predetermined amount, and controls delay amounts of delay means of the other color signals in accordance with the phase differences of the other color signals such that phase differences of the other color signals are removed, the delay means comprising: analog delay means having a delay amount of less than one pixel; and digital delay means having a delay amount of one pixel or more, the control means performing analog control of the analog delay means and performing digital control in one pixel units of the digital control means.
