ABSTRACT:
The invention relates to an automatic background brightness control device for color sorting apparatus having a plurality of sorting channels (Q1-Qn), each including a sensor (S1-Sn) to detect the amount of reflected and/or transmitted light from objects to be sorted and the amount of reflected and/or transmitted light from a background provided at the sorting channel. A scanner circuit (12, 14, 16) selects from the sorting channels one sorting channel of which the background brightness is to be controlled. A process control circuit (11) is provided to compare the output from the sensor against predetermined reference voltages and to produce a signal for controlling the background brightness only when the output from the sensor deviates from the reference voltages. A light control circuit (P1-Pn) controls the background brightness within the selected sorting channel according to the signal for controlling the background brightness.
