Abstract:
A color range designation apparatus comprising:a color designation unit receiving both a designated pixel of a displayed image and color data of the designated pixel; a color range data calculating unit determining a range between a minimum color and a maximum color for the designated pixel based on the color data received by the color designation unit; and a color range data storing unit storing the color range determined by the color range data calculating unit for the input designation pixel, wherein, when a color of a different pixel of the display image, input as the designation pixel of the display image, input as the designation pixel, falls outside the color range stored by the color range data storing unit, the color range data calculating unit determines a range between a minimum color and a maximum color for the designation pixel based on the different designation pixel, so that the stored color range is renewed by the determined color range.
