Abstract: A domestic cooking or defrosting appliance including a heating region and a camera for obtaining images of food cooking or defrosting within the heating region, wherein the camera outputs video signals to a processor that drives a display means associated with the appliance and/or controls the cooking or defrosting operation of the appliance. The display means is conveniently situated on the appliance to show an easily-viewable image of the food obtained by the camera. The camera is sensitive to infra-red radiation and outputs video signals representative of the heat of the food. The processor can therefore convert infra-red information received from the camera into visible information to create a display on the display means representative of the infra-red information. Such a display is preferably color-coded in accordance with the local temperature of the food.
