ABSTRACT:
Strobe light emission is controlled with precision with precision of distance information. A photometry unit measures light reflected by an object to be photographed by preliminary emission in a collection of divided regions. An object distance detection unit detects an object distance. A distance precision determination unit determines a distance precision. A first calculation unit calculates a proper photometry level from an object distance. A second calculation unit calculates an identification level for identifying an abnormal reflection region on the basis of the proper photometry level and a distance precision. A determination unit compares the photometry values of the divided regions with the identification level, thereby determining an abnormal reflection region. A third calculation unit calculates the photometry values of reflected object light in the divided regions from which the abnormal reflection region is excluded. Strobe light photography is performed by controlling the main emission amount by the photometry values.
