Abstract: A color sorting apparatus has a singulator section, a color sorter and a conveyor which drops the sorted objects into appropriate collection bins. Objects for sorting are transported on an endless conveyor on wheels through the singulation and color sorting section.

The imaging device, such as a camera, supplies red, green and blue signals to an image processor which performs a color transformation and obtains a single composite hue value for each object or piece of fruit to be sorted. Based on a comparison of the hue value to user programmed grading criteria, signals are provided to the conveyor so that the objects are ultimately deposited in appropriate sorting bins.

Abstract: A circuit for detecting a specified color in a color image signal operates on first, second and third primary color signals from a color camera. A complementary color, resulting from additive mixing of two primary colors, is detected by taking the sum and differences of the signal representing the two primary colors. The third primary signal is subtracted from the sum signal to produce a vector sum signal and the difference signal is rectified. The signal which indicates the presence of a complementary color is generated by subtracting the rectified signal from the vector sum signal and comparing it to a fixed reference level. A primary color is detected by subtracting the sum signal from the third primary signal to produce the vector sum signal. Fine adjustment of the target color is obtained by amplifying the two primary color signals differentially to maintain a constant sum of the two primary color signals.
