Abstract
An imaging device has: a pixel unit including a first pixel and second pixels arranged around the first pixel and adapted to provide more brightness information than is provided by the first pixel; a directional property determination unit that determines a direction of an intensity distribution based on differences of the values of the second pixels; a correlation value calculation unit that calculates a correlation value of the values of the second pixels; and an interpolation processing unit that, when the correlation value is greater than a threshold based on a noise signal intensity in the values of the second pixels, interpolates a value of the first pixel that is based on the direction of the intensity distribution from the values of the second pixels and, otherwise, interpolates the value of the first pixel from the values of the second pixels without depending on the direction of the intensity distribution.
