Abstract
An apparatus for controlling the emission of an electronic flash is provided, which is used with a photographic camera of the type in which the photometry of reflection from a film surface is effected. The apparatus calculates an exposure period on the basis of TTL photometric value which prevails before shutter release, displays such exposure period, compares it against a synchronized period, and causes an integrating operation of a photocurrent to be delayed a given time interval if it is decided that the calculated period is greater than the synchronized period.
