PROBLEM TO BE SOLVED: To provide a person detection device in which person detection accuracy is not deteriorated even without performing correction of a video of a monitoring camera installed on the upper side. ! SOLUTION: A person detection device comprises: an image input part 1 which generates an image frame from a camera imaging video; a temporal change extraction part 2 which calculates the maximum value of the change amount of luminance in the same portion from a frame preceding by a predetermined number to a reference frame and calculates the dispersion degree of luminance from luminance change information on the same portion from the reference frame to an image frame after the predetermined number to determine a static state/dynamic state for each pixel; an inter-frame feature extraction part which creates a histogram consisting of two values of the dynamic state and static state for each cell by generating the cell consisting a plurality of pixels, and normalizes the histogram to calculate the m |
