    • An imaging apparatus for capturing a moving image performs backlight correction of an image and outputs a natural image. The imaging apparatus electronically captures an image of a subject. An optical system has a light amount adjustment function. An imaging unit reads an optical image of the subject that is formed by the optical system. An A/D converter subjects an output of the imaging unit to A/D conversion. A backlight correction unit converts the tones of an image read by the A/D converter using a conversion characteristic selected differently according to a spatial position and at least increases the luminance level of a dark region of the image. An instruction unit instructs to start backlight correction. A control unit operates the backlight correction unit based on an instruction signal output from the instruction unit, and decreases an exposure light amount of the optical system by a predetermined amount.
    • 用于捕获运动图像的成像装置执行图像的背光校正并输出自然图像。 成像设备以电子方式捕获被摄体的图像。 光学系统具有光量调节功能。 成像单元读取由光学系统形成的被摄体的光学图像。 A / D转换器对成像单元的输出进行A / D转换。 背光校正单元使用根据空间位置不同地选择的转换特性来转换由A / D转换器读取的图像的色调,并且至少增加图像的暗区域的亮度水平。 指令单元指示开始背光校正。 控制单元基于从指示单元输出的指示信号来操作背光校正单元,并且将光学系统的曝光光量减少预定量。
