Latest Patents
Steward Longhurst holds a patent for a "Method and system for determining colour from an image." This invention relates to the determination of the color of a color sample from an image of the color sample. In one embodiment, a color sample capture card is provided, which has printed color samples of known color values. An image of the test color sample is captured using domestically available equipment, such as a consumer digital camera or a camera-equipped mobile telephone. The image also contains the color sample capture card. The image is then transmitted to a remote color determination service for analysis. Regression analysis is performed using the RGB color samples in the image and known XYZ colors to characterize the color capture response of the image capture device. This allows for the determination of the XYZ color of the unknown color sample from the RGB color in the image. Ultimately, the color can be matched to a palette of paint colors to find a suitable match.
