Abstract: The invention is a colorimeter for measurement of the color of an object. The colorimeter comprises a hand-held probe which is similar in size and shape to a large writing pen and provides the capability of measuring the color of a spot or target on, or within, the surface of an object. A measurement is made while placing the tip of the probe against, or in close proximity to, the surface of the object. The calorimeter generates from a single measurement three color data points representing the reflectance of the spot measured at the wavelengths of three primary colors. From those data points, a microprocessor can perform analyses yielding a single color value represented in various standard formats, or it can compare the measured values with a preloaded table of values. The colorimeter can then present the results on a liquid crystal display. The colorimeter contains multiple light emitting diodes (LEDs) for successively emitting light of different colors toward a target, a light sensor for receiving light reflected from the target, and a light pipe for directing light from the LEDs to the target. The display may be an integral part of the probe or contained in a separate display module connected to the probe by an electrical cable.

Abstract: A method and apparatus for determining the condition of a test subject based on color uses a color measuring instrument to detect change in a color factor indicative of a condition such as a disease, spoilage, ageing, etc. A medical condition such as bilirubinemia that affects skin color can be detected. One measures color factors such as Hunter b and L in the subjects' skin color. For predetermined ranges of one color factor, in particular L, changes in the other color factor, e.g. Hunter b, above predetermined levels are indicative of the medical condition. In many cases, a single measurement of the color factors can be utilized as a warning of the likelihood of the medical or contaminated condition, if the ordinary range of the color factor is known for healthy individuals with skin coloration like that of the test subject. Even if there has been no baseline measurement and the test subject's color is such that a single reading of one or two color factors will not warn of the possible presence of the medical condition or contamination, sequential readings can indicate the presence or absence of the condition based upon changes in the measured color factor, or lack of changes. The color measuring techniques apply to a wide range of biological test subjects (e.g. hair, teeth, tissue, excretions, foods, soil, animals, plants). Methods and apparatus for determining accurate hair color classifications and appropriate coloring agents to bring about a selected change of color include a table of hair color classifications, a color measuring instrument to arrive at Hunter L, a and b for use in identifying a particular classification from the table and a database that identifies appropriate coloring agents based on a selection of coloring actions from a menu and the classifications of hair color.

Abstract: The system provides for controlling color reproduction of input color image data representing one or more pages or page constituents in a network having nodes (or sites). Each one of the nodes comprises at least one rendering device. The system distributes the input color image data from one of the nodes to other nodes, and provides a data structure (virtual proof) in the network. This data structure has components shared by the nodes and other components present only at each node. Next, the system has means for providing color calibration data at each node characterizing output colors (colorants) of the rendering device of the node, and means for producing at each node, responsive to the color calibration data of the rendering device of the node, information for transforming the input color image data into output color image data at the rendering device of the node. The information is then stored in the data structure in different ones of the shared and other components. Means are provided in the system for transforming at each node the input color image data into output color image data for the rendering device of the node responsive to the information in the data structure. The rendering device of each node renders a color reproduction of the page constituents responsive to the output color image data, wherein colors displayed in the reproduction at the rendering device of each node appear substantially the same within the output colors attainable by the rendering devices. The system further has means for verifying at each node that the information for the rendering device of the node properly transformed the input color image data into the output color image data, and means for revising the information stored in the data structure at the node responsive to results of the verifying means. Shared components of the data structure may also store color preferences selected by a user. The information producing means of the system may further operate responsive to both the color calibration data and the color preferences. The rendering devices in the system can provide color reproductions having three or four colorants, and may provide more than four output colors (color inks).

Abstract: The present invention provides a combination of first providing a coarse adjustment by varying the emitter power and duration of the emitter/detector exposure time, and then providing a fine adjustment by storing a correction value for each photodetector element. The adjustment for each photodetector corrects not only for the range, but also for the offset, providing two correction values. In a preferred embodiment, the low and high voltage reference levels for an analog to digital converter are adjusted and stored for each photodetector for each color.

Abstract: A spectrophotometer apparatus (200) is adapted to provide spectral reflectance measurements of object samples. The apparatus (200) comprises a source light (254) and a reflection optics assembly (264, 268). Signals representative of reflected light are analyzed and data provided to an operator representative of the spectral response characteristics of the object sample (252). The apparatus (200) further comprises a side sensor (276) having a fixed spectral response characteristic for compensating the reflectance measurements in accordance with the light intensity emanating from the lamp. For purposes of calibration, a series of time-sequenced measurements are made of a reference sample. Utilizing these measurements, the apparatus (200) provides computations of compensation coefficients for each spectral segment. The compensation coefficients are utilized, with the side sensor measurements, to provide normalization of the reflectance measurements for each segment and for each measurement within the timed sequence. For each segment, a scale factor is then determined. The scale factors, compensation coefficients and side sensor measurements are employed to compensate actual reflectance measurements, with further compensation provided by a determination of temperature coefficients.
