<p>In a recording apparatus, two-level halftoning processing of input image data (I sec xy,I min (xk,yk)), is performed in such a manner that the input image data (I min xy,I min (xk,yk)) is compared by a comparator (104) with a threshold value stored in a threshold memory (105,125), and the results (Pxy) of the comparison is stored as driving data in nozzle memories (112) corresponding to a recording element, respectively. This two-level halftoning processing is performed (n-1) times, thereby n-level halftoning processing of the input image data (I sec xy,I min (xk,yk)) is performed. <IMAGE></p> |
