摘要： In order to efficiently controlling a compressing feeder of refuse, a novel detector system for existence or non-existence of refuse, a novel detector system for stagnation of refuse, and a novel system for preventing stagnation of refuse, are disclosed. The refuse existence detector system comprises an image pick-up device, an A/D converter for an analog image signal, a background image memory, a luminance variation detector, a background image selector, a subtractor for subtracting a background image signal from a digitized image signal, a binary encoder for issuing binary-coded image difference signal, an area calculator for calculating an area of an image region where the binary-coded image difference signal is binary "1", and a determinator device for determining whether existence or non-existence of refuse on the basis of the output of the area calculator. The refuse stagnation detector system and the refuse stagnation preventing system are constructed on the basis of a similar inventive concept.
