    Abstract: A method for measuring a color value such as brightness or intensity of a sample which comprises: measuring color values for a plurality of color standards using a reference color measurement device to obtain a matrix Y that contains the measurements of the color standards as measured by the reference color measurement device; measuring the same plurality of color standards with a field color measurement device to obtain a matrix X that contains the measurements of the color standards as measured by the field color measurement device; calculating a color correction matrix B based upon the equation Y=BX, measuring the color value for the sample with the field color measurement device, and applying the color correction matrix B to the reading of the sample color to obtain a sample color value that approximates that sample color value that would be obtained using the reference measurement device.

    Abstract: A method for isolating an element of an image made up of pixels comprising the steps of classifying the pixels into different groups based on the color value of the pixel, blurring the image, locating a pixel in the blurred image that has a predetermined color value corresponding to the element to be isolated, and growing a mask from the located pixel.

    Abstract: A sensor (10) for measuring reflective, transmissive, or self-luminous samples, comprises a plurality of light sources (18), where each of the light sources emit light of a substantially different wavelength band spaced in the visible spectrum; a reference channel photodetector (20); a sample channel photodectector (22); an optical cap (26) adapted to direct a first portion of the light emitted by each of the light sources to the reference channel photodetector (20); a reflector cone for directing a second portion of the light emitted by each of the light sources to the sample; and a receptor piece (36) for directing the diffuse portion of the light reflected from the sample to the sample channel photodetector (22). The sensor (10) is preferably incorporated into a hand-held "mouse" device, which includes an area on its top surface for seating an index finger of the human hand.

    Abstract: A sensor for measuring reflective, transmissive, or self-luminous samples, comprises a plurality of light sources, where each of the light sources emit light of a substantially different wavelength band spaced in the visible spectrum; a reference channel photodetector; a sample channel photodetector; an optical cap adapted to direct a first portion of the light emitted by each of the light sources to the reference channel photodetector, a reflector cone for directing a second portion of the light emitted by each of the light sources to the sample; and a receptor piece for directing the diffuse portion of the light reflected from the sample to the sample channel photodetector. Preferably, the reference channel and sample channel photodetectors are identical devices and are mounted back-to-back to share environmental characteristics, and in turn, minimize the variation between their respective responses. The sensor is preferably incorporated into a hand-held "mouse" device, which includes an area on its top surface for seating an index finger of the human hand. Positioned within this area is a pressure-activated switch that is operatively coupled to the sensor circuitry for performing the various readings. And the sensor is preferably mounted into the mouse device such that the focal aperture of the downward pointing reflector cone is in axial alignment with the pressure-activated switch. Accordingly, a user will be able to use the mouse to "point" with his or her index finger to an area of the sample surface, and will then simply press the switch using the same index finger.
