4.14 Output Image Processing
The output image data sent to the printer unit is subjected to the following processing:
4.14.1 Smoothing
The machine uses smoothing to remove the jaggy edges from diagonal or curved lines
of images, thus producing images consisting of smooth lines. Using smoothing, the ma-
chine can make moire associated with photo originals less conspicuous.
a. When Generating Read Images
The machine converts an 600x600-dpi input image into data of 1200 (equivalent) x
600 dpi by smoothing, which is carried out by relocating specific pixels in question.
b. When Generating Printer (PDL) Images
PDL data is subjected to appropriate smoothing, thus converting images of 600 x 600
dpi into images of 2400 (equivalent) x 600 dpi.
