Zusammenfassung:The present technique includes: an area-characteristic detector configured to calculate a maximum value, an average value, and a minimum value of signal levels of pixels around a certain pixel; a first gain creating part configured to calculate a first calculation value for the certain pixel; a second gain creating part configured to calculate a second calculation value for the certain pixel; and an adjustment part configured; to perform enhancement by multiplying the difference between the average value and the signal level of the certain pixel by the first calculation value when the signal level of the certain pixel is equal to or higher than the average value, and to perform enhancement by multiplying the difference between the average value and the signal level of the certain pixel by the second calculation value when the signal level of the certain pixel is lower than the average value.
