COLOR SEPARATION MULTIPLEXING FOR REAL-TIME DIMENSIONAL DEVICE CALIBRATION
First Claim
1. A method for processing a color image, comprising:
- receiving a plurality of device color separations for an image intended for rendering on a color image device,forming at least one intermediate image by interleaving pixels from at least two of the device color separations;
compressing the said at least one intermediate image in a compression module;
decompressing the said at least one intermediate image in a decompression module;
processing the said at least one decompressed intermediate image through a multidimensional calibration transform to output a calibrated device color separation; and
,said device color separations include at least three colors.

9. A method for processing a color image for a color imaging device, comprising:
-
receiving a plurality of device color separations for an image intended for rendering on a color image device, said device color separations include a first, second, and third color; forming at least one intermediate image by interleaving pixels from at least two of the device color separations, wherein said at least one intermediate image is formed by interleaving said first color, treated as the primary component, with functions of said second and said third colors, treated as a first secondary component; compressing the said at least one intermediate image in a compression module; decompressing the said at least one intermediate image in a decompression module; and
,processing the said at least one decompressed intermediate image through a multidimensional calibration transform to output a calibrated device color separation. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
