TECHNICAL FIELD This disclosure relates to technical fields of a display controlling apparatus, a display controlling method and a recording medium. BACKGROUND It is described in a patent literature 1 that a technique generates a difference image from an image, in which a face of a person passing through a gate is imaged from diagonally downward, detects a change area from the generated difference image, then, performs normalization processing on the detected change area, generates input information from the normalized image, and performs classifying normalized patterns by calculating similarity with registered dictionary information. It is described in a patent literature 2 that a technique turns an optical axis of a camera into a passage line joining an edge of an inlet and an edge of an outlet, sets observation conditions of the camera such that an essential observation area Q, which is determined by a range A along a width direction, in which a face of a pedestrian can pass, in a visual field of the camera, and a range B along a length direction, in which the face can move while an image for observation is acquired, is included in an observable area P of the camera, acquires an image which allows stable extracting features of the face of the pedestrian, and accurately observes the face of the pedestrian. It is described in a patent literature 3 that a technique images an image including at least a face of a pedestrian by a camera while the pedestrian presents from a C point to an A point in a travelling zone, determines whether or not the pedestrian is a person registered in advance by using an acquired image while the pedestrian M arrives a door from the A point, and unlocks the door when it is determined that the pedestrian is the person registered. It is described in a patent literature 4 that a technique images a person passing through a passageway leading to a gate, acquires a detection result from a detecting part disposed on a surface of the passageway, and controls an imaging timing by using the acquired detection result.
