Abstract
Abstract A camera apparatus, which performs a preliminary light emission before a main light emission for a photograph, comprising a photoelectric conversion part which output a photoelectric conversion data which corresponds to an incident luminous flux through a photograph lens, a preliminary light emission part which performs at least twice preliminary light emission of a first light emission which corresponds to the normal photographic region and a second preliminary light emission which corresponds to a close-up shot, a data acquisition part which acquires a photoelectric conversion data corresponding to the first preliminary light emission and the second preliminary light emission, respectively, a judgment part which judges whether it is a close-up shot or not based on the data obtained by the data acquisition part, and a setting part which sets a light emission condition of the main light emission based on a judgment result of the judgment part.

Dependent Claim
141 words
A camera apparatus, which performs a preliminary light emission before a main light emission for a photograph, comprising: photoelectric conversion means for outputting a photoelectric conversion data which corresponds to an incident luminous flux through a photograph lens; preliminary light emission means for performing at least twice preliminary light emission of a first light emission which corresponds to the normal photographic region and a second preliminary light emission which corresponds to a close-up shot; data acquisition means for acquiring a photoelectric conversion data corresponding to the first preliminary light emission and the second preliminary light emission, respectively; judgment means for judging whether it is a close-up shot or not based on the data obtained by the data acquisition means; and setting means for setting a light emission condition of the main light emission based on a judgment result of the judgment.
Claim 3
Dependent Claim
53 words
The camera apparatus according to claim 1 , wherein the acquisition means acquires the photoelectric conversion data in the state without light emission, and the setting means sets a diaphragm stop and a emission amount at the main light emission based on the each photoelectric conversion data obtained by the data acquisition means.
Claim 4
Dependent Claim
65 words
The camera apparatus according to claim 2 , wherein the setting means selects a photoelectric conversion data to which an emission amount at the main light emission can be calculated among at least twice preliminary light emission, and sets a diaphragm stop, in which the selected photoelectric conversion data is obtained, at the preliminary light emission as a diaphragm value at the main light emission.
Claim 5
Dependent Claim
37 words
The camera apparatus according to claim 1 , wherein the preliminary light emission means sets a diaphragm stop at a second preliminary light emission to be narrower than a diaphragm stop at a first preliminary light emission.
