    • A control device is provided for controlling a light emission device. The control device includes a light metering unit configured to acquire respective light metering values from a plurality of light metering regions. The control device further includes a correction unit configured to correct information about a light metering value of a target region based on a result of comparison between the light metering value of the target region and the light metering value of the light metering region at the periphery of the target region among the plurality of light metering regions, the result being acquired by the light metering unit allowing the light emission device to perform pre-flashing. Also, a calculation unit is provided which is configured to calculate a main light emission amount of the light emission device based on the information about the light metering value corrected by the correction unit.
    • 提供一种用于控制发光装置的控制装置。 所述控制装置包括:光计量单元,被配置为从多个测光区域获取各自的测光值。 控制装置还包括校正单元,其被配置为基于目标区域的测光值和周边的测光区域的测光值之间的比较结果来校正关于目标区域的测光值的信息 所述多个测光区域中的目标区域,所述结果由所述光计量单元获取,从而允许所述发光装置执行预闪光。 此外,提供了一种计算单元,其被配置为基于由校正单元校正的关于测光值的信息来计算发光装置的主发光量。

    • A reflector used in a strobe device has a rounded reflecting portion, a first pair of planar reflecting portions and a second pair of planar reflecting portions. A shape of the rounded reflecting portion is defined by a portion of a cylinder and by the rounded reflecting portion contacting a portion of an outer surface of a light source used in the strobe device. The first pair of planar reflecting portions is connected to the rounded reflecting portion, such that the first pair of planar reflecting portions is tangential to the outer surface of the light source. The second pair of planar reflecting portions is connected at a distal end of the first pair of planar reflecting portions. An opening of the reflector is defined between the distal ends of the second reflecting portions.
    • 用于选通装置的反射器具有圆形的反射部分,第一对平面反射部分和第二对平面反射部分。 圆形反射部分的形状由圆柱体的一部分和通过与选通装置中使用的光源的外表面的一部分接触的圆形反射部分限定。 第一对平面反射部分连接到圆形反射部分,使得第一对平面反射部分与光源的外表面相切。 第二对平面反射部分在第一对平面反射部分的远端连接。 反射器的开口限定在第二反射部分的远端之间。
