OPERATING METHOD OF THERMAL IMAGE DETECTIING DEVICE

摘要

According to an embodiment of the present invention, a method for operating a thermal image detecting device comprises the steps of: acquiring a first thermal image including an object; processing the first thermal image acquired; detecting a first pixel number of the object based on the first thermal image processed; acquiring a second thermal image which includes the object and has a predetermined time difference between the first and the second thermal images; processing the second thermal image acquired; detecting a second pixel number of the object based on the second thermal image processed; and detecting the motion of the object based on the detected first and second pixel numbers.
