<p>PROBLEM TO BE SOLVED: To realize operation of a man-conveyer without passenger residence by setting a residence detecting region for detecting passenger residence for an image inputted by an image input means, and by calling attention with a guide means when an object exists in the residence detecting region more than a designated time. SOLUTION: During operation of a man-conveyer, an image processing device 3a is started, takes in an image at a doorway with a camera 1a, sets a residence detecting region based on this image, and records the information. It photographs a background image to record it, and performs differential process between the present image and the recorded background image, and converts the differential process result to a binary image with an image conversion circuit 104. Using the binary image after noise removal, a histogram process circuit 105 creates x-axis and y-axis projection distributions. Then, it judges extent of traffic on the man-conveyer from area of a step region, calculates the in-region residence time, and when residence's occurrence is judged, performs attention guidance with a guiding device 22a.</p> |
