摘要： A triggering method for a produce recognition system which uses historical ambient light level readings. The method includes the steps of obtaining first ambient light levels from an ambient light sensor of the produce data collector with a data collection aperture covered, obtaining second ambient light levels from the ambient light sensor with the data collection aperture uncovered, determining a threshold ambient light level from the first ambient light levels and a difference between the first and second ambient light levels, obtaining a third ambient light level from the ambient light sensor with a produce item adjacent the data collection aperture, comparing the third ambient light level to the threshold ambient light level, and capturing data associated with the produce item if the third ambient light level is less than the threshold ambient light level.
