This paper deals with extraction method of moving objects using a temporal linear filter and digital subtraction. The temporal linear filter estimates in sequence background image that changes slowly according to environment, and the temporal linear filter needs inter frame operation but dose not need inter pixel operation in the same frame. This makes processing faster and simple. A moving object has the higher velocity, its spectrum band becomes the wider compared with the spectrum of background image. We are able to regard the spectrum of moving object as white noise. So, we may compose the temporal linear filter as the matched lowpass filter. As a result, we are able to extract moving objects by subtracting estimated background image from input image.<br>At the end of this paper, we show usefullness of this method to extract moving vehicles.
