PURPOSE:To appropriately maintain the exposure balance between main and subordinate objects by calculating the timing of flashing based on the brightness of the subordinate object at the time of rear light and correcting the calculated timing according to the difference in brightness between the main and subordinate objects, a distance to the main object can be flashing amount. CONSTITUTION:The exposure controlled has a control IC 22, temporarily calculates the timing of flashing, that is, a period of time until flashing after opening a shutter, corrects the timing of flashing according to the difference in brightness between the main and a subordinate objects, the distance to the main object, etc., and actuates flashing at the corrected timing. This correction prevents over-exposure as much as the incidence of light on the subordinate object while flashing continues. |
