  • Image display apparatus and frequency adjustment method thereof
    Publication number: 20100238349
    Abstract: A format of an inputted video signal is estimated to be based on the total number of vertical lines, and a frequency dividing ratio of a PLL unit is provisionally set at a predetermined value corresponding to the estimated format. Next, the frequency dividing ratio is calculated so that a measured value of a horizontal display width that is measured by a video detecting unit matches a capture width which is the horizontal display width capturable by a frame memory, and the calculated frequency dividing ratio is converted to a multiple of 4. A phase adjustment of the regenerative dot clock is performed against the video signal based on the converted frequency dividing ratio by using the regenerative dot clock generated by the PLL unit.
