Abstract
Frequency characteristics of an optical low-pass filter () 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 (), i.e. a frequency component region lower than one half of the Nyquist frequency fs of the sampling frequency fs of the image sensor (), is not higher than a specified value. An output image signal is created from a pixel signal created by the image sensor () so that N pixel signals (N is real number of 2 or above) created by the image sensor () correspond to one output image signal.
