Grayscale Preprocess
Select a maximum of 10 types from the following 21 filters for a captured gray image. The combination is called
a preprocess group, and a maximum of 16 preprocess groups (A to P) for 1 type and 1 camera can be stored.
This preprocess function is the data common to all checkers.
1.
Select one from preprocessing group A to P in "Grayscale Preprocess".
2.
Select "Filter Type" and specify the desired filter from 21 types.
Selectable preprocessings are as follows.
Dilation / Erosion / Erosion -> Dilation / Dilation -> Erosion / Auto Correct. / Gray Cut / Area Averaging /
Correction Setting / Median / Smoothing / Sobel / Prewitt / Laplacian / Edge Extract. X / Edge Extract. Y /
Sharpen / Tophat / Dynamic / Frequency Extract. / Rotation / Reflect
Refer to Chapter 4.6.5 in the PV200 User's Manual for the details of preprocess filters and setting
procedure.
If a part of module or bar is missing due to uneven print density, the image can be improved by
effectively performing preprocessing and the reading stability is improved.
