A moving body tracking system includes: a selecting unit () that select a target camera from a plurality of cameras disposed in a monitored area; a moving body detecting device () that extracts features of a moving body detected in an image captured by the target camera; a comparing unit () that compares the extracted features with the features of a tracking target moving body, to identify the tracking target moving body; a tracking managing unit () that tracks the movement of the tracking target moving body in the monitored area based on the position of the target camera and the time at which the image including the moving body was captured; and an elevator information acquiring unit () that acquires elevator operation information indicating an operation status of an elevator from an elevator system. When the tracked moving object boards an elevator, a selecting unit () refers to the elevator operation information to specify a target floor that is a floor on which the tracking target moving body is likely to unboard the elevator and selects at least one camera disposed on the target floor out of the plurality of cameras as the target camera.

In a state in which an optical axis of a camera is normal to a surface, a relative angle of a projector with respect to the camera is set such that a marker is formed at the intersection of the optical axis of the camera with the surface. In a state in which the relative angle is unchanged and an installation angle of the camera is changed, the marker formed on the surface is shot by means of the camera, and, based on a distance between the marker and the intersection in the image obtained by the shooting, the installation angle of the camera is calculated. Furthermore, an error of the calculated installation angle with respect to a target value is calculated and displayed. Calculation or adjustment of the installation angle can be made even if the surface on which the marker is formed is relatively narrow.

An imaging object tracking system includes an entrance/exit detection camera to take an image of an entrance/exit detection area where an imaging object enters and exits, an entrance/exit detection upper sensor to detect the imaging object being imaged by the entrance/exit detection camera, at least one upper sensor disposed so as to overlap a part of the detection area for detecting the imaging object with an area where the entrance/exit detection upper sensor detects the imaging object, an initial position estimation unit to estimate an initial position of the imaging object on the basis of positional coordinates of the imaging object in a two-dimensional image taken by the entrance/exit detection camera and three-dimensional coordinate information of the entrance/exit detection area, an upper position detection unit to detect a position of the imaging object seen from an upper side thereof, an initial motion path generation unit to generate an initial motion path, and a tracking unit to generate a following motion path by adding a position of the imaging object to the initial motion path.

The image update timings of a plurality of display devices are adjusted by calculating, in their image reproduction/updating control means (), the phase difference between a synchronization adjustment signal (SAS) created from synchronization adjustment data (SAD) received from the transmitting apparatus TA by a data reception means () and an image display control signal (HC) output to the image display means (), and increasing or decreasing the period of the next and subsequent image display control signals (HC) according to the phase difference, thereby reducing the phase difference. Image updating in the plurality of display devices can be synchronized to within a fixed tolerance range.

Multi-screen display system

An in-vehicle information system that notifies passengers in a vehicle of guidance information, including a display input unit having a display unit that displays the guidance information and an input unit that covers the display unit and detects touch operations by the passengers to be output as input operation information, and an information control unit that switches and outputs the guidance information to the display unit according to driving states of the vehicle and classifies the guidance information into first information to be provided to the passengers according to the input operation information and second information to be provided to the passengers according to the driving states of the vehicle to output the first information to the display unit according to the input operation information.
