Abstract: Optical feedback for controlling color of light from a light source is provided. Incident optical energy of the light is detected as a function of discrete steps of wavelength. For each discrete step of wavelength, an X, Y and Z tristimulus subvalue is produced. All the X, Y and Z tristimulus subvalues for all the discrete steps are summed together to produce an X, Y and Z tristimulus value for the light. The X, Y and Z tristimulus values are used as feedback in controlling color of the light generated by the light source.

Abstract: In the color information measuring device, the print object information measuring device, the printing device and the electronic equipment, three light fluxes of mutually different wavelengths applied to a measurement object from a red LED, a green LED and a blue LED of a light-emitting part have a common illumination area on the measurement object. The common illumination area on the measurement object contains such an observation area on the measurement object that a reflected ray is made to be incident on a photodiode via a condenser lens and a slit member. Therefore, the common illumination area in which three light fluxes of different wavelengths overlap with one another can reliably be made to be an observation area, so that intensities of a plurality of reflected rays of different wavelengths derived from the observation area can be observed equivalently, hence an improved measurement accuracy.

Abstract: A colorimeter or color measuring device measures color of a sample or an object, and displays measurement value or values according to user defined index or indices, calculated by a user-defined formula. Data of the user-defined formula is read in from outside of the colorimeter and converted into a coded form which can be executed by a controller of the calorimeter. The data of the user-defined formula or the coded data is stored in the colorimeter. Accordingly, the colorimeter has good portability and convenience despite its capability of expressing the colors of various samples or objects by user-defined original index or indices.

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.
