Abstract
An image processing device includes a first image inputting unit, a comprehensive first characteristic quantity data determining unit, a second image inputting unit, a second characteristic quantity data determining unit, and an image correcting unit. The first image inputting unit is configured so as to be capable of inputting a plurality of first images. The comprehensive first characteristic quantity data determining unit determines comprehensive first characteristic quantity data based on the plurality of first images inputted by the first image inputting unit. The second image inputting unit is configured so as to be capable of inputting a second image. The second characteristic quantity data determining unit determines second characteristic quantity data expressing a characteristic of the second image inputted by the second image inputting unit. The image correcting unit corrects the second image based on the comprehensive first characteristic quantity data and the second characteristic quantity data.
