ABSTRACT:
By comparing the density values of the pixels of a specific color separation image of an original comprising an objective image stored as data in an image memory with a threshold, determining a border line between the area of which density value is higher than the threshold and the area of which density value is lower than the threshold as the conclusive outline of the objective image, and by applying to both the areas distinct data respectively, an image extraction mask data is obtained to be stored into a mask memory.
