The invention relates to a detection device (100) capable of being installed in a passenger compartment of a motor vehicle defined by an observation window, comprising: an image sensor (130); an optical system (110), optically associated with the image sensor (130) and including controllable focussing means; a control module (120) designed to control the focussing means so as to consecutively focus on two at least partially separate areas of the observation window, and to obtain first and second corresponding images of the observation window; and an analysis module (126) designed to detect a mass of material located on the observation window, by analysing said first and second images of the observation window. The invention also describes a motor vehicle provided with a detection device and an associated detection method.
