<p>Case 3435 AUTOMATIC CALIBRATION CONTROL FOR COLOR GRADING APPARATUS Raymond E. Babb Inventor Apparatus for color grading of products such as fruits, vegetables, et cetera, employing a light source for illuminating the product and means for detecting and comparing the reflectance to measure certain product properties. For calibration, a target of known color is moved in front of the light source and the resulting signal is compared with a reference signal to generate a modifying signal. For automatic calibration of the apparatus this modifying signal is stored and thereafter used to adjust all subsequent readout signals.</p> |
