Abstract
A produce recognition system comprises an image capture device arranged to (i) capture a first color image which is representative of a color image of a produce item, and (ii) capture a second color image which is representative of a color image of at least one target color swatch. The produce recognition system further comprises control circuitry arranged to (i) calculate one or more color correction factors based upon differences between the captured second color image and a store of reference color images, and (ii) apply the calculated one or more color correction factors to the captured first color image to correct for color variations in the color image of the produce item due to a combination of variations in natural lighting and variations in interior lighting.
