<P>PROBLEM TO BE SOLVED: To enable preliminary light emission without increasing emitted light quantity of a flashing device while performing photometry and imaging by a single imaging device. <P>SOLUTION: The camera system includes: a luminous flux splitting member 102 splitting luminous flux from a subject transmitted through a photographic optical system 101 to reflected light and transmitted light; a photodetector 105 receiving the luminous flux from the subject; and a control means 106 capable of switching between first photometry processing and second photometry processing, the first photometry processing that the luminous flux splitting member 102 is arranged in a photographing optical path between the photographic optical system 101 and the photodetector 105, and the transmitted light is received by the photodetector 105, so as to perform photometry, and the second photometry processing that the luminous flux splitting member 102 is made to retreat from the photographing optical path, and the luminous flux from the subject is received by the photodetector 105, so as to perform the photometry. <P>COPYRIGHT: (C)2010,JPO&INPIT |
