This disclosure relates to performing proper strobe light photographing which
is almost free from the influence of the object reflectance and an autofocus detection
error. This disclosure includes a first calculation unit which calculates first
photometry data on the basis of a photometry value obtained by a photometry unit
for measuring light reflected by an object to be photographed by preliminary emission,
an object distance detection unit (#120) which detects object distance information,
a second calculation unit (#121) which calculates proper second photometry
data corresponding to the object distance information, a third calculation unit
(#122 and #123) which calculates third photometry data on the basis
of the calculation results of the first and second calculation units, and a control
unit (#124 to #126) which controls an main emission amount and performs
strobe light photographing on the basis of the calculation result of the third
calculation unit.
