Array 12 begins reading out its portion of line 1 (first line A) after a time delay, which provides a time overlap, t , such that the last elements from array 10 &e A) output simultaneously with 8 e corresponding first elements of array 12 (line A); i.e., the element in the overlap region of array 10 which contains the signal from a specific pixel on document scan line A and the element of array 12 containing the signal from the document pixel are outputted simultaneously, so they may be added in real time. Array 12 then continues to read out its portion of successive document lines in the same manner as array 10, except for the initial delay.
