Abstract: A system and method for use in testing and calibrating both electronic and traditional photographic devices. An illuminator with solid-state emitters and having independent control of both output spectral characteristics and power level enable the system and method to accurately test and calibrate the desired equipment.

Abstract: An illuminator suitable for accurate colorimetric work in electronic imaging and traditional photograghic environments uses an integrating chamber, a plurality of light emitting diodes (LEDs) and a controller for controlling the emitted energy form the LED. An LED support member assures that the beam of energy will be directed along a predetermined path between the energy inlet end and energy outlet end of the integrating chamber. Energy of a predetermined wavelength is filtered from entering the integrating chamber.

Abstract: A method of calculating a set of color-correction matrix coefficients for an image capturing device uses an LED illuminator having programmable output characteristics and spectral characteristics. A first XYZ data set is created from computed tristimulus values for each of the object stimulus. An image of each one of the predetermined set of object stimulus is captured thereby producing a plurality of images. RGB values are determined and normalized for each image thereby creating an RGB data set. A set of color-correction matrix coefficients are then calculated for the RGB data set corresponding to the first XYZ data set, thereby producing a color corrected RGB data set.
