In a method for detecting a background-color level in accordance with a selected region, if the selected region does not contain a large amount of background color, the background-color level cannot be detected accurately. Thus, an image signal of a region read by an image reader is input, a part of the read region is selected, a background-color region is detected in accordance with the image signal of the input read region and an image signal of the selected region, and a background color contained in the selected region is removed in accordance with the level of an image signal of the detected background-color region.
