|Title:||PASSENGER CONVEYOR INSPECTION DEVICE, INSPECTION SYSTEM, AND INSPECTION METHOD|
A passenger conveyor inspection device whereby it is possible to inspect the interior of a truss without separately preparing an image to be captured. This passenger conveyor inspection device is equipped with: an image reading unit which reads image information from video information relating to the interior of the truss; a luminance measurement unit which measures the luminance of each horizontal line of the image corresponding to the information read by the image reading unit; a region selection unit which selects the line region satisfying the specific luminance distribution conditions from the plurality of horizontal lines of the image corresponding to the information read by the image reading unit, on the basis of the histogram of the luminance measured by the luminance measurement unit; an image extraction unit which extracts information relating to each of the images in the region selected by the region selection unit, from the information relating to each of the plurality of images along the longitudinal direction of the truss 1; and a combined image information generation unit which generates image information by vertically combining the images corresponding to the information extracted by the image extraction unit.
