The mutual intensity function for a partially coherent light is used to develop an expression for the output intensity distribution for a broadband optical information processor. The coherence requirement for smeared image deblurring and image subtraction is then determined using the intensity distribution. We also quantitatively show the dependence of coherence criteria on the spectral bandwidth, the source size, deblurring width, spatial frequency, and the separation of input object transparencies.
