Claim Text:
1. A moving object tracking device, for generating a screen in which a movement line indicating a movement path of a moving object is superimposed on a real-time image of a monitored area, the moving object tracking device comprising: a processor; and a memory storing instructions, wherein the processor, when performing the instructions stored in the memory, comprises: a moving object detector that detects the moving object from images of the monitored area and outputs detection position information of the moving object; a first movement line generator that removes erroneous detection information included in the detection position information by use of a smoothing algorithm and generates a determined movement line optimized as the movement path of the moving object based on the detection position information having the erroneous detection information removed; a second movement line generator that generates a provisional movement line interpolating an undetermined section between a substantially latest detection position of the moving object indicated by the detection position information and an end point of the determined movement line; and a movement line information obtainer that obtains movement line information relating to an integrated movement line comprising the determined movement line and the provisional movement line integrated together; and a screen generator that generates, based on the movement line information, the screen in which the movement line is superimposed on the real-time image of the monitored area, such that both the determined movement line and the provisional movement line are included together in the screen before the end of the determined movement line reaches the latest detection position of the moving object, wherein an end of the provisional line substantially matches the latest detection position of the moving object, wherein the second movement line generator generates, as the provisional movement line, an undetermined movement line connecting the detection positions indicated by the detection position information in chronological order, without use of the smoothing algorithm.
