Claim:
An image processing apparatus comprising: a boundary line designating unit which designates a boundary line for dividing a screen into at least first and second selectable regions each containing an image to be processed, the first region being inside of the boundary line and the second region being outside of the boundary line; a region selecting unit which allows a user to arbitrarily select either one of the first and second selectable regions designated by the boundary line designating unit as a selected region to be processed in which an image is to be processed; an input accepting unit which receives a user's input of positioning of the boundary line which the user arbitrarily designates irrespective of a position of the image displayed on the screen; and a display position detecting unit configured to detect that the image is displayed on the boundary line designated by the boundary line designating unit, wherein when the display position detecting unit detects that the image is displayed on the boundary line, the region selecting unit selects a part of the image displayed on the boundary line excluded from the region to be processed as the region to be processed.
