Abstract:
1. A picture processing device comprising: 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 to be subjected to a correction in an input picture signal; a first gain creating part configured to calculate a first calculation value for the certain pixel, from a value of difference between the maximum value and the average value; a second gain creating part configured to calculate a second calculation value for the certain pixel, from a value of difference between the minimum value and the average value; and a signal amplitude 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.
