Abstract
Apparatus for automatically synchronizing a camera with an electronic flash is provided in accordance with the teachings of the present invention. The inventive apparatus determines if a photographing mode employing an electronic flash has been established by detecting whether or not a power source of the electronic flash is enabled. Upon a detection of a photographing mode employing an electronic flash, an exposure period synchronized with the operation of the electronic flash is automatically established. However, when no electronic flash is to be utilized, an exposure period appropriate to an automatic photographing mode is established.
