Abstract
The contour correction processing of a still picture that can suppress the generation of a black edge due to an undershoot in a contour portion is enabled while increasing a feeling for resolution. Moreover, an interpolation device that improves the sharpness of a digital picture is provided without increasing a circuit scale.
