<P>PROBLEM TO BE SOLVED: To reduce consumption power of a trigger signal detection device. <P>SOLUTION: The device is provided with: a trigger signal input circuit TG1 which receives a trigger signal "input", and outputs a first signal "output" for a predetermined time; a clock gating circuit CG1 which outputs a clock "clock_s" if the clock and the first signal are given; a counter CT1 which starts a counting operation and outputs a count value if the clock output from the clock gating circuit is given; and a time setting circuit TS1 which outputs a second signal AA if the count value output from the counter reaches a predetermined value, and gives it to the trigger signal input circuit, and stops the first signal output. <P>COPYRIGHT: (C)2009,JPO&INPIT |
