PURPOSE:To easily latch signal data by selecting a delay synchronizing signal corresponding to each dot clock through a data selecting means which is controlled with a display mode signal. CONSTITUTION:Delay synchronizing signals H1-Hn selected with adjusted setting signals S1-S3 are supplied from respective data selectors 23-25 to a data selector 26, so one of them is selected according to a mode decision signal and a reference signal at the time of adjustment becomes a reference signal at the time of use as it is. Thus, respective image adjustment switches corresponding to respective mode decision signals from a signal source are set at the time of the adjustment to make image adjustments in those modes. Even when the selection of the dot clock of the signal source is altered during afterward use, the reference signal at the set point of time is automatically selected by a 4th data selector 26, so display data are latched corresponding to the respective display modes without altering the settings and an image at the time of adjustment can be reproduced. |
