Abstract

See full text

A multiscreen display is formed in which changes in luminance between an image overlap area and areas outside the image overlap area are less visible across a range of low to high gradations. An offset correction value Doffset that is linearly decreased at the lowest gradation of the input image signal so that the offset correction value becomes 0 at gradations higher than the predetermined gradation Lset, is added to an input image signal.
