Abstract
The flashing controller according to the present invention comprises an optimal light value computer for computing an optimal quantity of light, a full flashing light value memory for storing an actual quantity of light for full flashing, a difference computer for computing a difference between a quantity of light for full flashing and an optimal quantity of light, and a difference output/flashing time memory for storing the relationships between the difference output and the flashing time of a flashing apparatus. For controlling the flashing time of a strobe, a difference between an actual quantity of light for full flashing and an optimal quantity of light is used to specify a flashing time. Then, a flashing time control controls flashing of a strobe circuit. Using the controller, influence of a reflector whose specifications tend to be determined at a late stage can be programmed independently during manufacturing. This helps reduce a production risk and improve precision in flashing control.
