1. An imaging system comprising: an image capture device, the image capture device providing a captured image of a plurality of objects; a depth detector, the depth detector providing depths relative to the image capture device; a display; and an image processor programmed to: receive the captured image from the image capture device; receive information of a plurality of selected objects, the plurality of objects including the plurality of selected objects and at least one non-selected object, wherein the plurality of selected objects is a plurality of lymph nodes, each of the plurality of lymph nodes storing an amount of IndoCyanine Green; receive a depth corresponding to the plurality of selected objects from the depth detector; generate a modified processed image by: modifying normal processing, without eliminating or replacing any part, of an entire image of each selected object of the plurality of selected objects in the captured image according to a function of at least the depth by modifying images of the plurality of lymph nodes so that fluorescences resulting from the amounts of IndoCyanine Green stored in the plurality of lymph nodes are scaled to a common depth for comparison purposes in order to identify a sentinel lymph node among the plurality of lymph nodes, and not modifying normal processing of an image of the at least one non-selected object; and provide the modified processed image to the display, so that the modified processed image is displayed on the display.
