Beschreibung
Zusammenfassung:	A color adjustment device (100) comprises an image characteristic amount acquiring unit (10), a specific-color-area determination unit (20), and a color compensation unit (30). The image characteristic amount acquiring unit (10) acquires the image characteristic amount of an input image from the average luminance or additional information of the input image. The specific-color-area determination unit (20) determines a specific color area based on the image characteristic amount. With reference to the specific color area, the color compensation unit (30) calculates the degree of similarity of the input color of the input image to the specific color, and performs the color adjustment of the input color of the input image with respect to at least one specific color. The area of the input image which is comparatively wide and possesses a color of the same system as the specific color is not wrongly recognized as the area of the specific color.
