Abstract
A method and an apparatus for detecting smoke by way of analysis of at least one video image recorded by a video camera monitoring an area. At least one moving area of the at least one video image is tested for the probable presence of smoke by determining the direction and the size of the moving area. If the test result is positive, at least part of the at least one moving area is evaluated with respect to the presence of smoke as a function of at least one item of information that is characteristic of smoke.
