Abstract

Apparatus for processing fruit and the like, particularly for sorting as a function of variables, including color, blemish, size and shape. The apparatus provides an illuminator for substantially uniformly illuminating a portion of the item being examined, and for generating a plurality of signals corresponding to respective different portions of the item being examined. A circuit is provided for obtaining difference signals corresponding to the difference of data signals corresponding to adjacent portions of the surface of the fruit. The fruit is sorted as a function of those difference signals.
