Spectrocolorimeter imaging system
View Patent ↗A spectro-colorimeter system for imaging pipeline is provided, the system including a camera system; a spectrometer system; and a controller coupling the camera system and the spectrometer system. In some embodiments the camera system is configured to provide a color image with the first portion of the incident light. Also, in some embodiments the spectrometer system is configured to provide a tristimulus signal from the second portion of the incident light. Furthermore, in some embodiments the controller is configured to correct the color image from the camera system using the tristimulus signal from the spectrometer. An imaging pipeline method for using a system as above is also provided. Further, a method for color selection in an imaging pipeline calibration is provided.
1. A spectro-colorimeter system for imaging pipeline comprising:
a camera system including a separating component and a camera, the camera further comprising an RGB camera and the separating component further comprising a mirror, said mirror further comprising an aperture, used to direct a first portion of an incident light to the camera system;
a spectrometer system including an optical channel, a slit, and a spectroscopic resolving element, the separating component directing a second portion of the incident light to the spectrometer system through the optical channel; and
a controller coupling the camera system and the spectrometer system, wherein:
the camera system provides a color image with the first portion of the incident light;
the spectrometer system provides CIE colorimetric values from the second portion of the incident light; and
the controller receives RGB data from the camera system; receives CIE colorimetric data from the spectrometer system; provides a color correction matrix transforming the RGB value provided by the camera system into CIE colorimetric values; and provides an error correction to the camera system so that camera system imaging settings are adjusted.
