ABSTRACT:
A digital imaging device captures an image and generates a color signal from the image for application to an output device having specific color sensitivities, the imaging device further being one of many devices of the same type useful with the output device. The digital imaging device, for example a digital camera, includes a color sensor for capturing the image and generating a color signal from the captured image, the color sensor having predetermined spectral sensitivities, and an optical section that is interposed in the image light directed to the color sensor, the optical section also having predetermined spectral characteristics. The combination of the spectral sensitivities of the color sensor and the spectral characteristics of the optical section uniquely distinguish this particular imaging device from other imaging devices of the same type. By providing a set of matrix coefficients uniquely determined for this imaging device, the matrix coefficients optimally correct the spectral sensitivities of the color sensor and the spectral characteristics of the optical section for the color sensitivities of the output device.
