Abstract
The subject matter disclosed herein relates to color calibration for digital imaging devices. Color correction may be performed for digital imaging devices. A response of a device to known colors may be obtained. The response may be obtained at least in part through an image that may include one or more color patches. One or more linearization curves may be determined by fitting values from one or more color patches within the image to reference data. In addition, a color correction matrix may be determined by estimating local minimum values utilizing one or more pairs of high-chroma color patches within the image.
