    摘要: 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.

    摘要: A wheel position detecting device and a tire air pressure detecting device including the wheel position detecting device are provided. The wheel position detecting device includes triggering devices and a receiver mounted on the vehicle-body side, and transmitters mounted on the wheels. Each triggering device outputs a trigger signal to each transmitter. In response to the trigger signal, each transmitter transmits a frame to the receiver. The receiver receives the frame and judges whether the transmitter is mounted on a subject wheel, based on whether reception strength indicated by reception strength data stored in the frame is within a range set in advance.
