Abstract
An image processing apparatus capable of extracting a particular image area from an image by designating a color hue of the desired particular image area. After indication on one or more points in an object region of interest, an initial range of hue or of brightness is designated, and a predetermined color is painted throughout a region adjacent to the indicated point(s) and having a hue or brightness, respectively, within the predetermined range. If that process results in the coloring of an area exceeding that which the operator desires to cover, the predetermined range of hue or brightness, as the case may be, is narrowed, and the process is repeated.
