<P>PROBLEM TO BE SOLVED: To provide an automatic door sensor and an automatic door opening/closing system which, can reduce the unnecessary opening/closing of a door by image processing and secure safety during the opening/closing of the door at low cost. <P>SOLUTION: When a door 300 is closed, an imaging area SR1 and an imaging area SR2 which face the surfaces of the door 300, respectively, are photographed by a camera part 101a and the camera part of the automatic door sensor 100b, respectively. When the door 300 is moved from the closed state to the open state, the imaging area of the camera part of the automatic door sensor 100b includes the forward of the end of the door 300 in the advancing direction. In this case, the imaging area SR1 of the camera part 101a is maintained. When the door 300 is fully open, an area including the forward of the end of the door 300 (outdoor side) is photographed by the camera part 101a, and an area including the forward of the end of the door 300 (indoor side) is photographed by the camera part of the automatic door sensor 100b. <P>COPYRIGHT: (C)2011,JPO&INPIT |
