METHOD AND DEVICE FOR CHARGING FLASH DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for charging a flash device by which the charging time of the flash device is not prolonged and an effect by the charging of the flash device is prevented from being exerted on the other circuits. SOLUTION: If this charging method, a main capacitor C2 is charged while cutting off such a state that a current reversely flows to the DC-DC converter of a charging circuit 6 driven by charging signals P1 and P2 from a ground GND2 being in common with the A/D circuit 3 of the DC-DC converter by a diode D6 when it is charged with high-voltage electric charge for a flash device generated by the DC-DC converter of the charging circuit 6.
