摘要:
Generating a color profile for a digital input device. Color values for at least one color target positioned within a first scene are measured, the color target having multiple color patches. An image of the first scene is generated using the digital input device, the first scene including the color target(s). Color values from a portion of the image corresponding to the color target are extracted and a color profile is generated, based on the measured color values and the extracted color values. The generated color profile is used to transform the color values of an image of a second scene captured under the same lighting conditions as the first scene.
