PROBLEM TO BE SOLVED: To perform display control capable of performing excellent display to the input signals of various display modes. SOLUTION: Horizontal synchronizing signals separated in a synchronizing signal separation part 11 synchronize a clock generation part 14 through a delay part 13. Separated image signals are A/D converted by the clock and stored in a data storage part 16. A system control part 12 judges the display mode and a display resolution based on the synchronizing signals, performs automatic display start position adjustment, automatic display width adjustment and automatic phase adjustment for stored data based on the judgement and adjusts the sampling divider value of the clock and the delay amount of the delay part 13. Image data after the adjustment are interpolation-processed corresponding to the display resolution and then, displayed at a dot matrix display device 110. |
