Hardware Options Océ

Every scanner offers some hardware features, which can be accessed via this panel. Of course this panel may be different with different scanners. But this one is which we use for all Océ scanners. Depending on the selected color depth some of the features may be disabled.


 
Threshold
The threshold defines whether a point is scanned as white or black point. This option is only enabled in connection with the Line Art mode.
Dynamic
The built in DSP (Digital Signal Processor) does a two dimensional analysis on the scan line and adjusts the threshold automatically.
 
Line Enhancement
This process is a bit more difficult. It analyses the relative size of a scanned pixel in relation to the actual selected resolution. Any line, which would be smaller than one pixel, is increased to one pixel. Any larger line is increased by one pixel.
 
Invert
Inverts the color channel. The result is a negative image.
 
Vertical Adjustment
This value is to adjust the vertical scaling factor. It affects the scaling of the intermediate scan lines in the steps of 0.01%.
