Abstract: In optical filter systems and optical transmission systems, an optical filter compresses data into and/or derives data from a light signal. The filter way weight an incident light signal by wavelength over a predetermined wavelength range according to a predetermined function so that the filter performs the dot product of the light signal and the function.

Abstract: An output current from each pixel sensor can be extracted at an arbitrary ratio by a current divider. An arithmetic control unit sets the dividing ratio in correspondence to a color matching function. The current components are added together by a summing amplifier so that a signal corresponding to a tristimulus value is composed and then converted into a digital signal. That is, weighting by weight factors corresponding to color matching functions of CIE 2-degree observer is performed in a stage of analog signal processing.

Abstract: A produce recognition system and method which use an internal reference to calibrate a produce data collector. The produce data collector collects first data from an external reference, collects second and third data from an internal reference, and collects fourth data from a produce item. A computer determines a first calibration value from the first and second data and a second calibration value from the third data and applies the first and second calibration values to the fourth data to produce fifth data. The computer further obtains sixth data from reference produce data and compares the fifth and sixth data to identify the produce item.
