Abstract
A noise reduction section includes: a correlation detector configured to detect correlations between corresponding pixels between first and second image signals which are obtained from an identical image, and output degrees of correlation based on the detected correlations; an addition ratio determining section configured to determine addition ratios of the corresponding pixels between the first and second image signals based on the degrees of correlation, where the addition ratios are used in weighted addition averaging processes; and a weighted addition averaging section configured to perform, based on the addition ratios, the weighted addition averaging processes on the corresponding pixels to generate an output image signal, wherein when each of the degrees of correlation is relatively high, the addition ratio determining section provides a relatively high proportion of the pixel of the second image signal in the addition ratio.
