Abstract
A controller reads a header information, which is input from a picture information acquisition unit, stores the header information in a storage unit, and reads a frame rate code corresponding to picture data to be displayed from the storage unit according to displayed time information contained in the header information. Furthermore, the controller sets the dot clock frequency in response to the read frame frequency in a dot clock output unit, outputs a display control signal to an output unit in order to compare the currently set frame frequency and the frame frequency just prior to the currently set frame frequency. If both flags are not in agreement, then the controller outputs a display control signal to the output unit wherein the display control signal indicates a picture set by the frame rate which differs from the just prior frame rate, and commands the dot clock output unit to switch a dot clock.
