    • In an electronic camera according to the present invention, an electric charge is stored in a CCD as a light receiving signal having at least color information with respect to received light beams. Standard color information is acquired by an imaging circuit and a main CPU from the light receiving signal obtained by driving the CCD in such a manner that a stored electric charge quantity to be stored in the CCD becomes a predetermined quantity. On the other hand, reference color information is acquired from light receiving information obtained by driving the CCD. An application range of an amplification ratio of the light receiving signal determined based on the reference color information with respect to the standard color information is stored in a detachable memory.
    • 在根据本发明的电子照相机中,电荷被存储在CCD中,作为至少具有关于所接收的光束的颜色信息的光接收信号。 通过成像电路和主CPU从通过驱动CCD获得的光接收信号以使存储在CCD中的存储电荷量成为预定量的方式获得标准颜色信息。 另一方面,从通过驱动CCD获得的光接收信息获取参考色彩信息。 基于参考颜色信息确定的相对于标准颜色信息的光接收信号的放大率的应用范围被存储在可拆卸存储器中。
