摘要： In a colorimetric apparatus including a support base configured to support a colorimetric object, a carriage including a detection unit configured to detect a detection target portion formed at the colorimetric object, the carriage supporting a colorimeter, and a movement unit configured to move the carriage, an adjustment value is calculated based on a detection position of the detection unit where the detection unit is caused to detect a detection target portion and a color measurement position of the colorimeter where the colorimeter is caused to measure a color of the detection target portion, and a position of the carriage at the time when a color of a patch is measured is adjusted based on the adjustment value.

摘要： A measuring device is a measuring device that performs colorimetry of an evaluation patch formed on a medium and a paper white patch that is a portion exposed by the medium. The measuring device has a light source portion that irradiates the medium with an illumination light, a measurement portion that acquires an amount of light from the medium as a measurement value, a memory that holds a paper white standard value that is a reference measurement value of the paper white patch, and a colorimetry unit that corrects a measurement value of the evaluation patch based on the measurement value of the paper white patch and the paper white standard value. Even in a case where a measurement position is changed, a reflectance of the evaluation patch is accurately calculated and a chromaticity of the evaluation patch can be accurately acquired.

摘要： An embodiment of a method for compensating variations in an attenuation of light of an optical filter of a light sensor system comprises illuminating a clear sensor and a color sensor of the light sensor system with a test light having a test spectrum. Therein the color sensor comprises the optical filter and is designed to predominantly sense light with a wavelength within a pass band of the filter; and the test spectrum has components outside the pass band. A clear test signal generated by the clear sensor and a color test signal generated by the color sensor are received in particular in response to the illumination with the test light. Then a first transmission value T is determined based on the clear test signal and on the color test signal. Finally, a compensation factor Kr, Kg, Kb is calculated to compensate the variations in the attenuation of light based on the first transmission value T and a nominal transmission value Tn of the filter.
