ABSTRACT:
A camera having an electronic flash that is energized on the basis of a release signal comprises a control unit for controlling an amount of a light emitted from the electronic flash, a measuring unit for measuring an amount of a light incident thereon through a lens system, and a memory for storing data indicative of the light amount measured by the measuring unit. The control unit controls the electronic flash in such a manner that, after the electronic flash is energized during a first period of time when the release signal is input, on the basis of data stored in the memory and light reading data measured by the measuring unit when the electronic flash is energized during the first period of time, the electronic flash is re-energized only during a second period of time.
