Abstract
A device captures a digital image of a color of interest and a physical color calibration chart. A corrected color value of the color of interest is determined based on the physical color calibration chart and the color of interest as captured within the digital image. A selected color value for the corrected color value is determined, as a closest color value within a predetermined color space or as a spot color value within the predetermined color space.
Claims15
A system comprising:
- a communication mechanism to communicatively connect with a device to receive therefrom a digital image of a color of interest and a physical color calibration chart;
- and
- a logic mechanism to determine a corrected color value of the color of interest from the physical color calibration chart and the color of interest as captured within the digital image, and to determine a selected color value for the corrected color value, as a closest color value within a predetermined color space or as a spot color value within the predetermined color space,
- wherein the communication mechanism is further to transmit the selected color value to one or more of the device and a different device.
A non-transitory computer-readable data storage medium storing logic executable by a mobile device having image-forming capability to perform a method comprising:
- capturing a digital image of a color of interest and a physical color calibration chart;
- and
- determining or receiving one or more of:
- a corrected color value of the color of interest from the physical color calibration chart and the color of interest as captured within the digital image;
- and
- a selected color value for the corrected color value within a predetermined color space.
A method comprising:
- determining, by a computing system, a corrected color value of a color of interest captured within a digital image;
- determining, by the computing system, a selected color value for the corrected color value, as a closest color value within a predetermined color space or as a spot color value within the predetermined color space;
- and
- outputting, by the computing system, the selected color value.
