摘要
PURPOSE:To obtain a division irradiating type flash illuminating system in which the light distribution of field is controlled according to the circumstances of the distribution of an object in the field by using one flash tube, a division irradiating type flash device and a camera to which the division irradiating type flash device is attached. CONSTITUTION:The spatial distribution circumstances of the object are grasped based on the result of range-finding by a rangefinding means 103 in every range-finding area, the irradiating light quantity of every irradiated area corresponding to the range- finding area is calculated in accordance with the spatial distribution circumstances of the object by a 1st light quantity calculation means 104, and a light quantity emitted from one light emitting part 100 is adjusted by a light quantity adjusting part 101. Furthermore, for a range-finding area where range-finding is impossible because the contrast of the object is low, for example, the irradiating light quantity of the irradiated area corresponding to the area where rangefinding is impossible is calculated based on the object distance in an area where range-finding is possible by a 2nd light quantity calculation means 105.
