System and method for optimizing image resolution using pixelated imaging devices

Abstract

A method of processing image data for display on a pixelated imaging device is disclosed. The method comprises: pre-compensation filtering an image input to produce pre-compensation filtered pixel values, the pre-compensation filter having a transfer function that approximates the function that equals one divided by a pixel transfer function; and displaying the pre-compensation filtered pixel values on the pixelated imaging device. In another disclosed method, the method further comprises: pre-compensation filtering an image input for each of a plurality of superposed pixelated imaging devices, at least two of which are unaligned, to produce multiple sets of pre-compensation filtered pixel values; and displaying the multiple pre-compensation filtered pixel values on the plurality of superposed pixelated imaging devices.

I claim:  
     
         1 . A method of processing image data for display on a pixelated imaging device, the method comprising: 
 pre-compensation filtering an image input to produce pre-compensation filtered pixel values, the pre-compensation filter having a transfer function that approximates the function that equals one divided by a pixel transfer function; and    displaying the pre-compensation filtered pixel values on the pixelated imaging device.    
     
     
         2 . A method according to    claim 1   , in which the method further comprises: 
 pre-compensation filtering an image input for each of a plurality of superposed pixelated imaging devices, at least two of which are unaligned, to produce multiple sets of pre-compensation filtered pixel values; and    displaying the multiple pre-compensation filtered pixel values on the plurality of superposed pixelated imaging devices.    
     
     
         3 . A method according to    claim 2   , in which the method further comprises: 
 displaying the multiple pre-compensation filtered pixel values on six imagers, the six imagers being positioned into four phase families, the first and third phase families corresponding to separate green imagers, the second and fourth phase families corresponding to separate sets of aligned blue and red imagers.
