Patent ID: RE39712

Claim:
A digital imaging device for capturing an image and generating a color signal from the image for application to an output device having specific color sensitivities, said imaging device further being one of many devices of the same type useful with the output device, said digital imaging device comprising: a color sensor for capturing the image and generating the color signal from the captured image, said color sensor having predetermined spectral sensitivities; an optical section having predetermined spectral characteristics, said optical section interposed in image light from the image directed to the color sensor thereby imparting the predetermined spectral characteristics to the image light, the combination of the spectral sensitivities of the color sensor and the spectral characteristics of the optical section uniquely distinguishing the imaging device from other imaging devices of the same type; and a set of matrix coefficients uniquely determined for the imaging device in order to generate an optimized color signal , wherein said matrix coefficients are ( a ) automatically calculated by a matrix coefficient calculation from image data obtained by the color sensor from a color chart and ( b ) used for correcting the spectral sensitivities of the color sensor and the spectral characteristics of the optical section for the color sensitivities of the output device.
