摘要

The invention relates to a device, a method and a system for drawing a track. On the device, the user selects a tracking target region on a frame displayed by a display (500), sets an information obtaining unit (352) to obtain tracking target information of the region, and saves the information in a tracking target information storage unit (354). Then a tracking target tracking unit (353) tracks a target object according to the obtained tracking target information and a probability distribution image generated by a predetermined tracking method, and saving tracking result data into a tracking result data storage unit (356). An image generating unit (359) relates each frame of the tracking result data to color information and connects the center coordinates of a frame of a previous position with the center coordinates of a frame of a next position.
