At the time of processing of an image signal from an image sensor mounted in a small electronic apparatus (e.g. a mobile apparatus), in order to remove noise, certain steps are performed, in accordance with embodiments. Edge values may be detected from an area to be smoothed to detect a feature point. Weights depending on a geometric distance with respect to the feature point may be applied to pixels distributed in the smoothed area. A brightness value as reference may be calculated in consideration of a difference in brightness between a center pixel and a peripheral pixel. Weights may be applied depending on the brightness values of the pixels to perform smoothing. It may therefore be possible to effectively remove noise while maintaining the level on the edge area. |
