    • An exposure control apparatus for controlling an exposure adjustment mechanism on the basis of a captured image signal includes the following elements. A face detecting unit detects a face of a person appearing in a captured image on the basis of the captured image signal. A histogram data determining unit determines histogram data by setting a face detection region in the captured image according to detection information and detecting at least a brightness value of the face detection region from the captured image signal. A target brightness setting unit sets a target brightness range for desired brightness of the face. An exposure control amount determining unit determines, when a face is detected, an amount of control for the exposure adjustment mechanism by comparing the target brightness range with a brightness value at a peak of the histogram data or a brightness region in the vicinity of the peak.
    • 基于拍摄图像信号控制曝光调整机构的曝光控制装置包括以下要素。 面部检测单元基于所捕获的图像信号检测出现在拍摄图像中的人的面部。 直方图数据确定单元通过根据检测信息设置拍摄图像中的面部检测区域并从捕获的图像信号中至少检测面部检测区域的亮度值来确定直方图数据。 目标亮度设定单元设定面部所需亮度的目标亮度范围。 曝光控制量确定单元通过将目标亮度范围与直方图数据的峰值处的亮度值或峰值附近的亮度区域进行比较来确定当检测到面部时的曝光调整机构的控制量 。
