Abstract:
To prevent determination accuracy from lowering due to reflection of smoke.SOLUTION: Passage determination means includes: threshold determining means for determining a threshold; object presence/absence detecting means for detecting the presence/absence of an object in each of multiple first determination areas, on the basis of the threshold determined by the threshold determining means, by comparing respective image data values of multiple first determination areas in multiple image data captured within a predetermined period with the corresponding reference image data value; and passage order determining means for comparing change mode information indicating the mode of change of the presence/absence of the object in each of multiple first determination areas in the multiple image data with reference change mode information stored in advance that corresponds to the mode of change when the object passes through the passage, and if they are matched, determining that the object has passed through the passage. The threshold determining means changes the threshold according to the change in the brightness of a predetermined second determination area in the image data that is obtained via imaging means.SELECTED DRAWING: Figure 37
