Patent ID: 7446764

Claim:
A display control device that causes a display screen to display predetermined image information, comprising: a display adjustment signal superimposing unit that superimposes a display adjustment signal for adjusting timing of displaying a pixel in accordance with image information, on a portion of a signal corresponding to a region outside the display screen on a horizontal scanning line; an image signal sampling unit that performs sampling for an image signal in accordance with the image information in predetermined sampling timing; a display control unit that performs display control for the pixel, using a value obtained through the sampling performed by the image signal sampling unit; a display adjustment signal sampling unit that performs sampling for the display adjustment signal in predetermined sampling timing; an optimum display timing detecting unit that detects optimum timing of displaying the pixel by changing the sampling timing in the display adjustment signal sampling unit, based on a value obtained through the sampling performed by the display adjustment signal sampling unit, until the optimum timing of displaying the pixel is determined; and a timing adjusting unit that adjusts the sampling timing in the image signal sampling unit to the optimum display timing, when the optimum display timing detecting unit detects the optimum display timing.
