PROBLEM TO BE SOLVED: To properly correct each scene in an object picture by correcting picture data based on correction information prepared by composing correcting information with respect to the whole area of picture data and correcting information with respect to a mask area based on weighting data. SOLUTION: Correcting information with respect to the whole area of picture data and correcting information with respect to a mask area are prepared based on the distribution of luminance, weighting data are prepared based on the distribution of the mask area, and these two pieces of correcting information are composed based on weighting data to prepare correcting information to correct picture data. In this device, a weighting data preparing part 8 prepares the weighting data based on mask data stored in a picture buffer 3 to store in the buffer 3. A picture correcting part 9 corrects picture data stored in the buffer 3 based on an LUT stored in an LUT holding part 5 and the weighting data stored in the buffer 3 and stores it in the buffer 3. |
