1. An imaging device comprising an imaging section; an overlapping area identifying section which identifies overlapping areas of images consecutively captured by the imaging section; a texture judging section which judges whether amount of texture within areas of a predetermined range in the overlapping areas identified by the overlapping area identifying section is larger or smaller than a predetermined reference value; an adjusting section which adjusts pixel values of the images so that pixel values of the overlapping areas come within a predetermined range, based on a judgment result by the texture judging section; and a combining section which combines the images whose pixel values have been adjusted by the adjusting section, such that the overlapping areas coincide with each other.
