1. A door controlling system comprising:
- a video imaging device that monitors at least a door panel and a door panel travel area through which said door panel moves between said open and closed positions, said video imaging device being operable to receive images of the door panel within the door travel area;
a detection system comprising a video signal processor and a memory, said video signal processor capable of communicating with said video imaging device, said memory containing a plurality of stored initial images of the door panel within the door travel area, each of said stored initial images corresponding to one of a plurality of positions of the door panel within the door travel area;
a door operator constructed and arranged to be operatively connected to said door panel and adapted to communicate with said detection system, said door operator operable to move the door panel between the open and closed positions through the door panel travel area;
a position sensor communicated to said detection system for monitoring the positions of the door panel within the door panel travel area; and
the detection system operable to determine whether a person or object other than the door panel is within the door panel travel area by comparing the images of the field of view, including the door panel therein, against the stored initial images of the door panel within the door travel area for the corresponding positions of the door panel as monitored by the position sensor.

5. A method for controlling a door panel, comprising:
-
monitoring with a video imaging device positions of a door panel within a door panel travel area through which the door panel travels, and generating signals based on said monitoring of the positions of the door panel;
monitoring with a position sensor positions of the door panel within the door travel area;
determining whether a person or object other than the door panel is within the door panel travel area with a processor by comparing the signals against initial stored images of the door panel within the door travel area stored in a memory, said stored images corresponding to positions of the door panel as monitored by the position sensor;
responsive to determining that a person or object other than the door panel is within the door travel area, transmitting a door opening signal.

6. An automatic door assembly, comprising:
- a video device that is capable of (a) receiving a video data signal comprising information representative of images received by a video imaging device and (b) processing the video data signal into a form suitable for displaying images that are visually representative of the images received by the imaging device;
a door panel constructed and arranged to be mounted for movement between a closed position and an open position;
a door controlling system comprising;
(i) a video imaging device constructed and arranged to be mounted in a viewing position wherein said imaging device monitors a field of view that encompasses at least an approach area located adjacent to the door panel, said video imaging device being operable to monitor the field of view by receiving images of the field of view and transmitting an internal video data signal comprising information representative of said images;
(ii) a detection system comprising a video signal processor that communicates with said video imaging device, said video signal processor being adapted to receive said internal video data signal from said imaging device and to process said internal video data signal to determine whether a person or object has entered said approach area, said detection system being adapted to responsively transmit a door opening signal in response to said processor thereof determining that a person or object has entered said approach area; and
a door operator constructed and arranged to be connected to said door panel and adapted to communicate with said detection system, said door operator being constructed and arranged to move said door panel from said closed position thereof to said open position thereof responsive to receiving said door opening signal;
said door controlling system being adapted to transmit an external video data signal comprising information representative of the images received by said imaging device, thereby enabling the external video data signal to be transmitted to the aforesaid video device so that the video device can process the external video data signal into a form suitable for displaying images that are visually representative of the images received by said video imaging device including at least the approach area adjacent said door panel said video imaging device comprising a video camera system that transmits signals that are used for both (a) said internal video signal that comprises information representative of said images transmitted to said video signal processor for determining whether a person or object has entered said approach area, to enable said detection system to transmit the door opening signal, and (b) said external video data signal to be transmitted to said video device that processes the external video data signal into a form suitable for displaying said images that are visually representative of the images received by said video camera system. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
