A control circuit 10 includes an internal clock generating portion (12), which starts generating an internal clock signal (LCLK) required by a control portion (11) to perform action when a specific signal pattern appears in a trigger signal, continually generates the internal clock signal (LCLK) at least before the control portion (11) completes predetermined processing, and then stops generating the internal clock signal (LCLK); and the control portion (11), which uses the internal clock signal (LCLK) to perform the predetermined processing. |
