    • An image sensor of an electronic camera photoelectrically converts a subject image obtained by a shooting optical system to generate an image signal. A image processing section generates face registration image data and moving image data. A face detecting section detects a face area inside a shooting screen based on the moving image data. A controlling section adjusts shooting parameters of the shooting optical system, depending on a position detected at the face area. A face image generating section cuts out an image of the face area to generate face image data. A face recognizing data generating section extracts feature points of the face of a captured person from a part of the face area of the face registration image data and generates face recognizing data. A recording section records the face recognizing data or face image data.
    • 电子照相机的图像传感器对由拍摄光学系统获得的被摄体图像进行光电转换以产生图像信号。 图像处理部生成面部登记图像数据和运动图像数据。 面部检测部基于运动图像数据检测拍摄画面内的脸部区域。 根据在脸部区域检测到的位置,控制部分调节拍摄光学系统的拍摄参数。 面部图像生成部切出面部区域的图像,生成面部图像数据。 面部识别数据生成部从面部登记图像数据的脸部区域的一部分中提取被拍摄者的面部的特征点,并生成脸部识别数据。 记录部分记录面部识别数据或面部图像数据。

    • A polarization converting element includes: a main body that is made from a transparent member; an incident section that is provided to the main body, and upon which light generated from a light source is incident; an annular reflecting section that is formed on the periphery of the incident section; and a polarization splitting section that is formed opposite to the annular reflecting section on the emission side of light incident upon the incident section. One polarized light component of the incident light passes through the main body and is emitted from the polarization splitting section. Another polarized light component of the incident light is reflected towards the annular reflecting section by the polarization splitting section, and is emitted from the polarization splitting section after having again been reflected by the annular reflecting section and having been converted into light of a same polarization component as the light of the one polarized light component.
    • 偏振转换元件包括:由透明构件制成的主体; 设置在主体上的入射部分,从光源产生的光入射到该入射部分; 环形反射部,形成在所述入射部的周缘上; 以及偏振分离部,其与入射在入射部的光的发射侧的环状反射部相对地形成。 入射光的一个偏振光分量通过主体并从偏振分离部分发射。 入射光的另一个偏振光分量被偏振分离部分反射向环形反射部分,并且在再次被环形反射部分反射并被转换为相同偏振分量的光之后从偏振分束部分发出 作为一个偏振光分量的光。
