A Geometrically Correct Composite Image Color is produced in the imaging camera by rotating a color wheel in front of the CCD imaging array. Eighteen spectral regions are represented on the color wheel, including the human red, green and blue spectra. A standard color photograph is created by repeating the imaging process three times, once for each of the three colors.
The out-of-focus, out-of-registration imaging stripe that lies at the far left of this image, as well as the one panel near the left center, resulted from the imaging camera having been somehow moved during the process of taking the same picture three times. Perfect color registration will occur only if the camera remains absolutely stationary during the three-photo imaging process. |
