ABSTRACT:
A high-speed flash charging system for a camera accelerates flash charging time by storing electrical energy in capacitors in a first charging section when photographing is started after power is applied. When the flash is to be emitted, the system transforms the stored energy and charges a second set of capacitors to be used for powering the flash. After charge is transferred from a capacitor in the first set to the second set, the system determines whether enough charge is present in the second set to activate the flash. If there is not enough charge present, another capacitor from the first set is discharged.
