The present disclosure relates to a flash generator for providing power supply to a flash tube so that the flash tube rapidly provides a light output adapted to FP-sync, Flat Peak. The flash generator comprises a capacitor bank, an output and a switch configured to switch a current flow from the capacitor bank via the output to provide a variable power via the output. The flash generator further comprises a controller for controlling the switch, whereby by controlling the on time of the switch, the generator is operative to provide, during a time period of 100 to 2000 s during a peak time period within the time period, an average power at least 4 times higher than the average power provided during the other time period within the time period, whereby the flash tube during the peak time period becomes fully ignited.

A flash unit that includes a flash generator having at least one energy storage element and at least two light source channels as well as having at least two flash tubes, the flash tubes being supplied with energy by the energy storage element by means of the light source channels. The flash unit further includes an energy quantity control device, by means of which it is possible to provide for each light source channel any desired energy quantity from a minimum charge to a maximum charge of the at least one energy storage element, and a color temperature control device, by means of which it is possible to set a color temperature for each light source channel independently of the energy quantity provided therefor. The functions of all light source channels are fully equivalent.

The local light filling can be performed on a point in a photographed image. Alternatively, by adjusting an inner width of the flash chamber, the illumination field of view of the flash matches the focal length of the optical system to which the flash is applied, thereby implementing light concentration at a telephoto end and light scattering at a wide-angle end.

The invention discloses a method for determining a starting time for a flash emitted from a flash tube of a flash apparatus. The flash apparatus comprises a triggering circuit, and a drive circuit. The method comprises the steps of measuring an electric current through and/or a voltage across an electrical component of the drive circuit, and determining the starting time for the flash based on the measured electric current and/or voltage.
