Abstract
A signal processor capable of extracting evaluated values used for automatic control more appropriately, including: a feature detection unit which detects a feature change position of any target pixel and its peripheral pixels in an input picture signal; a hold unit which holds the position information; a region creation unit which creates a region by excluding the held positions from an evaluated value extraction region; and an evaluated value extraction unit which extracts evaluated values in accordance with the region; wherein unnecessary portions different in feature from the periphery are extracted in accordance with any pixel unit by detection of the feature change position so that the feature change position is excluded from the evaluated value extraction region.
