Abstract
An image display device is arranged to convert analog video signals into digital video signals and display the corresponding image to the digital video signals. The image display device provides a variable delaying circuit for delaying an analog video signal of each color or a clock variable delay circuit for delaying a dot clock for generating each color dot clock and supplying each color dot clock as a conversion timing signal of an analog-to-digital converting circuit of the corresponding color. This kind of delay circuit is served to adjust a phase of the analog video signal or the dot clock of each color, thereby suppressing color blur even if the analog video signal contains skews among the colors.
