    Abstract: The present invention provides a combination of first providing a coarse adjustment by varying the emitter (1-1 to 1-n) power and duration of the emitter/detector exposure time (SL-1 to SL-n), and then providing a fine adjustment by storing (13) a correction value for each photodetector element (5). The adjustement for each photodetector corrects not only for the range, but also for the offset, providing two correction values. In a preferred embodiment, the low (offset) and high (offset plus range) voltage reference levels for an analog to digital converter (8) are adjusted and stored for each photodector for each color.

    Abstract: A colorimeter for reading color bars (403, 404) of printed sheets (401) or the like includes a longitudinally extending base (400) including a paper stop (442) along which a sheet to be tested for color may be positioned. An autonomously operating colorimeter head (410) is moved along the base in a direction parallel to the edge of the sheet by means of an electric motor (600) mounted on the base and driving an helical thread lead screw (418) engaging an X-axis carriage supporting the head. The head is moved by operation of the lead screw in a direction parallel to the edge of the sheet, referred to as the direction of the X-axis. The head includes an electric motor and a Y-axis transport supporting an optics unit (510). The optics unit is moved within the head in a direction parallel to a Y-axis, extending perpendicularly to the X-axis.

    Abstract: A densitometer apparatus (410) is disclosed and is adapted to provide color density measurements of object samples. The densitometer apparatus (410) comprises a source light (580) for projecting light toward an object sample comprising a control strip (588, 620). A reflection optics assembly (576) is adapted to measure light density reflected from the object sample when the object sample is in the form of a paper control strip. A transmission optics assembly (618) is adapted to measure transmission density of light rays projected through the object sample when the object sample is in the form of a film control strip. A motor assembly (426) operating with a drive wheel assembly (434) and idler wheel assembly (440) automatically moves the object sample (588, 620) through the apparatus (410) adjacent the source light (580). A pair of guides (468, 470) are selectively adjustable by the operator to control movement of the object sample (588, 620) through the apparatus (410). In response to input from a key switch assembly (492) activatable by the operator, the apparatus (410) is adapted to perform various color density measurement and calibration functions, and display appropriate information to the operator through the use of a visual display (490).

    Abstract: A portable colorimeter for characterizing the optical properties of a colored surface and in particular a colored surface containing metallic or pearlescent particles, which employs three multiangular spectrophotometric measurements to derive color constants for the surface. The colorimeter is a compact integrated unit housing irradiation, detection, control, analysis and display means and employs three illumination angles, preferably -30°, O°, and 65°, and one detection angle, preferably 45°, all measured from the sample normal. The method includes determining the tristimulus values of the color of the sample surface from low resolution spectral reflectance data preferably using twelve detector elements.

    Abstract: Apparatus for measuring the colour of a product and method of calibrating same is used for colour grading of products such as fruits, vegetables and food products being processed. The apparatus employs a light source (15) for illuminating the product and means (18) for detecting light reflected from the product to provide a signal that is a measure of the colour of the product. For calibration, a target (35) of known colour is moved in front of the light source and the signal resulting from the light reflected by the target is compared with a reference signal to generate a modifying signal. Means (36) are provided for automatic calibration of the apparatus whereby this modifying signal is stored and thereafter used to adjust all subsequent readout signals.
