Abstract

The present invention relates to an advertising information display system comprising a device for starting the display of the advertising information on certain elements of the display panels; a computer device receiving information from the output of the various infrared radiation pick-ups emitting logic signals towards the display monitoring and control device associated with each panel to cause the displacement of the message on the display panel elements in accordance with the movements of the camera.

emitting a signal from a camera position and detecting said signal at one of said panels, said signal being related to the shooting field of said camera,

starting the display of an advertising message each time at least one of the panels is located in the shooting field of an operating one of the cameras responsive to said detection, and

controlling the displacement of the message on the panels according to the movements of the camera in such a manner as to cause said message to continuously appear at approximately the same position within said television receiving means,

whereby said message continually appears at said television

receiving means.

2. A method according to claim 1, further comprising the steps of determining the size of said advertising message according to the operating focal distance of said camera in such a manner that the message is always entirely located in the shooting field of the camera.

10. A method according to claim 1, further comprising the step of, in case of a change of shooting field from a camera operating in medium-shooting-field mode to a camera operating in wide-shooting-field mode while remaining at the last shooting field considered after the end of a predetermined period, determining in an appropriate manner the location of the message on the various display panel elements.

11. A method according to claim 1, further comprising the step of, in case of an abrupt change by a camera of shooting display panel elements to other different panel elements and after excitation during a predetermined time of an infrared radiation pick-up of the other panel elements in the shooting field of said camera, determining the location of the message on the shot panel elements according to the speed of displacement of the camera from the display panel elements initially shot to the other panel elements.

12. A method according to claim 3, further comprising the step of, in case of a change from one camera shooting panel elements to another shooting panel elements with consecutive excitation of at least three infrared radiation pick-ups on the display panels of a duration shorter than a predetermined time, starting the display of the message on an appropriate number of display panel elements from the pick-up located four pick-ups farther than a third pick-up of the three pick-ups used for the interpolation of the speed of displacement of the camera from the panel elements toward the other panel elements.

13. A display system including a certain number of panels with display elements arranged at a place, a certain number of television cameras for televising to at least one television receiving means, at least one of the display panels appearing at said television receiving means when said display panels are in the shooting field of one of the cameras in operation, comprising:
