ABSTRACT:
In a method of calculating a color correcting condition for a color image composed of plural pixels each separated into plural primary color density values, a statistic indicating a relationship between a primary color density value and a number of pixels showing the primary color density value is made for each primary color; a specific density value corresponding to a predetermined statistic value for each primary color from the statistic is calculated; an extracting condition for each primary color is determined based on the obtained specific density value; specific pixels are extracted from the plural pixels of the color image so as to satisfy the extracting condition; and the color correcting condition is determined based on the plural primary color density values of the extracted specific pixels.
