Abstract

See full text

In the case where a gray-scale difference Δ1 between a pixel 110a and a pixel 110b, a gray-scale difference Δ2 between the pixel 110b and a pixel 110c are each larger than a threshold value, and Δ1>Δ2, gray-scale values of the pixels 110a, 110b and 110c are corrected into the gray-scale value of the pixel 110b+Δ1×(1−α), the gray-scale value of the pixel 110c+Δ2×(1−α), and the gray-scale value of the pixel 110c+Δ2×β, respectively (0≦α, β≦0.5). After the correction, a gray-scale different Δ1a between the pixels 110a and 110b, and a gray-scale different Δ2a between the pixels 110b and 110c satisfy the following formulas: Δ1a>Δ1, and Δ2a>Δ2, respectively.
