Abstract

If a scene change is not detected by a scene change detector, in each frame until a count value of a frame counter reaches a predetermined value, a tone curve pattern updater sets a representative point group of a tone curve pattern selected in the most recent frame in which a count value is reset to an initial value as a representative point group for updating. By assuming that k is a number less than 1, the tone curve pattern updater generates a first multiplication value obtained by multiplying the set representative point group for updating by a coefficient (1−k) and a second multiplication value obtained by multiplying the representative point group output by the tone curve pattern updater in an immediately preceding frame of each frame by a coefficient k, and outputs a combined representative point group obtained by adding the first multiplication value and the second multiplication value.
