내장형 오토 플래시 성능 측정방법에 관한 연구

초록

It is useful for photographers that flash is able to increase the intensity of radiation artificially in both indoor and outdoor. With developing technology, diverse kinds of auto flash can be used easily without photographic knowledge. Moreover, recent auto flash has an intelligent mechanism by using photographing information to reproduce object's original brightness. In spite of developing flash mechanism, measuring performance standard is devaluated as the measurement of generating power performance. Therefore, this study tries to measure the performance of auto flash objectively. With digital compact cameras using frequent auto flash, the distance between an object and a camera, a luminance of the object, and an ambient intensity and a camera are the independent variables, and the performance evaluation test carries statistics treatments and graphs.
