Abstract
In the case where a gray-scale difference Δ1 between a pixeland a pixel, a gray-scale difference Δ2 between the pixeland a pixelare each larger than a threshold value, and Δ1>Δ2, gray-scale values of the pixelsandare corrected into the gray-scale value of the pixel+Δ1×(1−α), the gray-scale value of the pixel+Δ2×(1−α), and the gray-scale value of the pixel+Δ2×β, respectively (0≦α, β≦0.5). After the correction, a gray-scale different Δ1a between the pixelsand, and a gray-scale different Δ2a between the pixelsandsatisfy the following formulas: Δ1a>Δ1, and Δ2a>Δ2, respectively.
