Method for mapping colors between imaging systems and method therefor

Abstract

A method for performing color conversion includes configuring a color transformer to perform black point scaling when converting image data from a source device to a destination device. Another method for performing black point adjustment while performing color management conversions includes determining a device independent black reference vector for a device that corresponds to a predetermined set of device dependent values for that device. Converting the device dependent values to device independent data and adjusting the device independent data based on the device independent black reference vector.

1 . A method for performing color conversion, comprising: 
 configuring a color transformer to perform black point scaling when converting image data from a source device to a destination device.    
   
   
       2 . A method as defined in  claim 1 , further comprising: 
 determining the amount of black point scaling performed based on a media which the image data will be printed on.    
   
   
       3 . A method as defined in  claim 1 , further comprising. 
 providing 100% black point scaling when the destination device comprises a display monitor.    
   
   
       4 . A method as defined in  claim 1 , wherein the color transformer receives color coordinates from the source device and transforms them using a color map.  
   
   
       5 . A method as defined in  claim 4 , wherein when the color transformer transforms the color coordinates from the source device using the color map the color transformer produces color coordinates that are used by the destination device.  
   
   
       6 . A method for performing black point adjustment while performing color management conversions, comprising: 
 determining a device independent black reference vector for a device that corresponds to a predetermined set of device dependent values for that device;    converting the device dependent values to device independent data; and    adjusting the device independent data based on the device independent black reference vector.    
   
   
       7 . A method for performing black point adjustment while performing color management conversions, comprising: 
 extracting black point information from at least one device profile; and    applying the black point information to a device independent color space when converting image data from a source device color space to a destination device color space.
