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.

摘要： Frequency characteristics of an optical low-pass filter (2) are set in such a way that a first false color passing rate indicative of the rate of frequency components passing through a frequency component region not lower than the Nyquist frequency fa for the lowest sampling frequency fs among the sampling frequencies in the longitudinal, the lateral, and the oblique directions for each color in an image sensor (5), i.e. a frequency component region lower than one half of the Nyquist frequency fs of the sampling frequency fs of the image sensor (5), is not higher than a specified value. An output image signal is created from a pixel signal created by the image sensor (5) so that N pixel signals (N is real number of 2 or above) created by the image sensor (5) correspond to one output image signal.
