Abstract: A method and system identify a target simplex (T7) and interpolate inputs of points (214, 216, 218) of the target simplex (T7) to identify a combination of inputs that achieves a target result (TR).

Abstract: An apparatus for color sensing is disclosed. The apparatus includes a set of color sensor tolerances for a Non-Contact color sensor device; and a Contact color sensor device, conforming to the set of color sensor tolerances.

Abstract: A device includes a housing; a color sensor within a first end of the housing, the color sensor configured to sense a color of a sample when the color sensor is placed proximate the sample; and a display within the housing, the display configured to display the color of the sample sensed by the color sensor.

Abstract: An inverse transfer function of a limited bit depth output device having N primary colorants (e.g., a six-color printer) is determined. An N-dimensional hypercube that has been tessellated into a set of simplices is accessed, and the set of simplices is navigated through to select a subset that defines a one-to-one mapping of device-independent color space to device primary space.

Abstract: A system and a method are provided for correcting the effect of non-uniform illumination on a reproduced image of a 2-D object. An image of a reference card in an illuminated setting is captured by an image capturing device. A 2-D object is placed in the same illuminated setting and the image of the object is captured. Next, a smoothing function for the reference card image is generated. The smoothing function is used to generate a smoothed reference card image. The smoothed reference card image is processed to compute inverse correction values, which are mathematical inverse of the pixel values in the smoothed reference card image. A pixel-by-pixel correction is then applied to the captured image of the 2-D object using the inverse correction values.

Abstract: A method and system for processing images to, for example, capture artwork includes capturing a target image and an image of a reference. The reflectance functions of the target image are then measured. The target image is processed, using the measured reflectance functions and the captured image of the reference, to calculate a correction transform associated with the captured target image.
