Apparatus for photographing that carries out a pre-flash photography

摘要

An apparatus for photographing by using an electronic flash has a photography controller that carries out a pre-flash photography by emitting strobe light in a pre-flash exposure period and subsequently carries out a main flash photography by emitting strobe light; and an exposure adjuster that sets at least one exposure value associated with the pre-flash photography and/or the main flash photography. The exposure adjuster sets an aperture value of a diaphragm that suppresses an occurrence of saturation in image-pixel signals that are generated in an image sensor in the pre-flash exposure period. The photography controller drives the diaphragm in accordance to the set aperture value for the pre-flash photography.

1. An apparatus for photographing by using an electronic flash, comprising:
a photography controller that carries out a pre-flash photography by emitting strobe light in a pre-flash exposure period and subsequently carries out a main flash photography by emitting strobe light; an exposure adjuster that sets at least one exposure value, said exposure adjuster setting an aperture value of a diaphragm that suppresses an occurrence of saturation in image-pixel signals that are generated in an image sensor in the pre-flash exposure period, said photography controller driving said diaphragm in accordance to the set aperture value for the pre-flash photography, and an image sensor driver that drives said image sensor, said photography controller controls said image sensor driver to set the pre-flash exposure period to be shorter than an exposure period in one frame/field interval during a through-mode.
