Abstract: PURPOSE:To read a video still picture by an image scanner by selecting a drive frequency lower than a drive frequency so as to read a signal and inputting the signal to a fetch means. CONSTITUTION:A same coincidence signal M is given to a clock changeover circuit 7, which selects a clock from a clock generating circuit A10 of an image scanner section whose clock frequency is, e.g. 1-2MHz slower than that of a clock generator B8 in the order of one digit from the clock generator B8 whose clock frequency is nearly 20MHz and the selected clock is applied to delay elements 9-1-9-3. An RGB parallel video signal of one horizontal line is converted into a consecutive signal by driving each delay element with a slower clock being a basic clock of the image scanner and the converted signal is fetched to an A/D converter 11 of the image scanner through a sample-and- hold S/H amplifier 14 and a changeover switch 15. Thus, the circuit equipped substantially with the image scanner is used maximizingly to fetch the video still picture signal to the image scanner, then the video still picture signal is read with a slight cost increase.

Abstract: PURPOSE:To improve the reliability of wiring, by using a common resist pattern, alternately depositing the insulating film of the first deposited film and the wiring metal of the second deposited film, performing only one lift OFF, thereby forming the wiring very simply. CONSTITUTION:A resist pattern 2 is formed on a ground layer 1, which is a substrate. The resist pattern 2 has a hole 3 corresponding to a wiring pattern in an area, where wiring is formed.
