发明名称 OPTICAL LOW PASS FILTER AND IMAGING DEVICE USING THE SAME
摘要 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.
