1. Apparatus for manipulating agricultural products such as fruits and vegetables, wherein the products emit or reflect distinctive radiation characteristics in the infrared spectrum comprising:

  • visual radiation detection means for detecting and generating a digitized visible image signal based on visual radiation, which is about 100 to 1000 nanometers, received from a given viewing area;

    infrared detection means for detecting and generating a digitized infrared image signal based on infrared radiation in the range of about 1000 to 2000 nanometers received from a given viewing area; and

    analyzer means for analyzing the digitized image signals and comparing selected characteristics of the signals with known stored characteristics that are distinctive of the products in the respective visual and infrared frequency ranges, the analyzer means generating a control signal capable of operating a digitized manipulating device whenever a predetermined number of characteristics are indicative of the presence of a product in the viewing area.
