    • An optical low pass filter (2) is formed, for example, by a birefringent plate so as to control the light beam separation width, thereby changing the cut-off frequency according to an imaging mode. The number of pixels of an imaging element (5) is set greater than the number of pixels corresponding to the dynamic image display resolution. In a still image capturing mode, the light beam separation width is set narrower so that the resolution of the imaging element (5) can be used as it is while suppressing generation of a false color to a certain degree. On the other hand, in a dynamic image capturing mode, the light beam separation width is set wider so that a high-frequency component corresponding to an unnecessary resolution component for an output image signal can be cut off and suppression of the false color can be performed strongly as compared to the still image capturing mode.
    • 光学低通滤波器(2)例如由双折射板形成,以便控制光束分离宽度,从而根据成像模式改变截止频率。 成像元件(5)的像素数被设置为大于与动态图像显示分辨率对应的像素数。 在静止图像拍摄模式中,光束分离宽度被设定得更窄,从而可以在一定程度上抑制伪色的产生的同时可以使用成像元件(5)的分辨率。 另一方面,在动态图像拍摄模式中,将光束分离宽度设定得较宽,从而可以切断对应于输出图像信号的不必要的分辨率成分的高频分量,并且可以抑制伪色 与静止图像捕获模式相比,强烈地执行。
