Imaging fire detector
First Claim
1. An image-producing fire detector, the fire detector comprising at least an imaging device (1), a processor (2), a memory device (3), and communication means (4, 5), wherein the processor (2) is designed such that the processor (2) outputs a fire alert as a function of an analysis of image sequences generated by the imaging device (1), and, if appropriate, transmits the fire alert using the communication means (4, 5).

Abstract
An imaging fire detector is used to detect a fire from a recorded image sequence. Either a video camera or an infrared camera is used as an imaging device. Characterizing parameters of a fire are either analyzed individually or in combination. In order to detect changes, an object analysis, a pattern analysis or a spatial-frequency analysis of the recorded image sequences is conducted. Using a threshold value for the duration of the changes, short-term changes are detected and discarded. In a further embodiment, the fire detector may also be used as a burglar alarm. With the aid of communication means, the fire detector transmits a fire alert to a master station.
