Table 2.3 Image processing function
No. | Function name | Details function |
|
|
|
1 | Separation | Recognizes the photo area and Line>drawing |
| ( Line>drawing/Photo ) | area in one scanning automatically, and |
| automatic separation | outputs data with applying dither processing or |
|
| error diffusion for the photo and the binarizing |
|
| for the line>drawing. |
|
|
|
2 | Outline extraction | Extracts the outline of the Line>drawing such |
|
| as a thick character. |
|
|
|
3 | Image emphasis | Emphasizes the black>white contrast to raise |
|
| the resolution. |
|
|
|
4 | Overlay | Overlays the pattern on the scanned data and |
|
| make the overlayed black data to white data. |
|
|
|
5 | Inversion | Converts white into black and black into white |
| (White/black conversion) | of read data (binary data). |
|
|
|
6 | Mirror image | Turns over the both sides of read data. |
|
|
|
7 | Simplified Dynamic | Changes the slice level of the binarizing |
| threshold | according to the density of the document. |
|
|
|
8 | Zooming | Magnifies or reduces the document in the range |
|
| between 25% and 400% with 1% step. Also |
|
| reads the document with different |
|
| magnification in horizontal and vertical |
|
| scanning. |
|
|
