1. An image processing system, comprising at least one processor configured to:
(step S1) acquire a target object image including a target object;
(step S2) detect, from the target object image, a plurality of outermost line segments in a region of interest of the target object image based on predetermined line segment detection processing;
(step S3) acquire, based on the plurality of outermost line segments, information about an outline of the target object in the target object image;
(step S4) process, based on the information, at least a part of the target object image so that the outline matches or approximates a predetermined outline;
wherein the at least one processor is configured to determine whether at least one of corners of the target object deduced from the information is outside the region of interest,
wherein the at least one processor is configured to perform the processing of the at least a part of the target object image when it is not determined that the at least one of the corners is outside the region of interest and wherein the at least one processor is configured to repeat steps S1-S4 when it is determined that the at least one of the corners is outside the region of interest;
and wherein the region of interest is a same or similar shape to the target object with an area that is a multiple of an area of the target object.
