-With this function an automatic image import is made by the selected device. No objects should be located on the image. The maximum values of the found pixels (grey tone) are indicated and can be used for a better definition of limit values in the process of the object identification. Ideally the value should be 255 (white) for a scanner, that means no objects (e.g. dust) was found. If the determined value should be smaller than 255, then an object identification is only possible below the measured value.+<div left>

-A detailed evaluation can be made by the chart of the colour distribution (see also chapter 5).

-=====6.5 Language===== 
- 
-The offered program languages are German and English.  
- 
- 
-=====6.6 Dpi and colour depth===== 
- 
-To set the required  resolution and colour depth you can use this menu item. 
-When creating images by a twain interface or loading MYP images this will be done automatically. The loading of formats like BMP and JPEG requires a manual input of these values. The results of the analysis depends directly on the parameter settings for image resolution  
- 
-  
-Figure 27. Resolution and colour depth 
- 
- 
-=====6.7 Magnification coefficient===== 
- 
-The magnification coefficient as well has a big influence on the analysis results. The manual input is required if images are created by a microscope or a digital camera (see chapter 2.3). 
- 
- 
- 
- 
-=====6.8 Scan method===== 
- 
-Use this menu item to select one o the following analysis method : 
-\* 2D area calculation or  
-\* counting raster intersection points (see chapters 4.1 and 4.5). 
- 
- 
-=====6.9 Save image data===== 
- 
-If this option is selected, the user will be requested for saving the image date after scanning or creating. So the original image data can be stored automatically. 
- 
- 
-======7. Extra====== 
- 
-=====7.1 Cut and count===== 
- 
-This menu item provides a tool for the manual counting of image objects. The current image file will be divided into subframes according to the setting given in field Cut after. 
- 
-  
-Figure 28. Setting for image cutting 
- 
-Press the button Cut in order to cut the image and to reset the counter readings. 
- 
-  
-Figure 29. Cut and count 
- 
-All subframes are listed in the left scrollbox. The active frame marked with a red border will be displayed on the work space. 
-In the example shown in figure 29 the image was cut into 15 subframes. By means of the keys 5 (forward) and 4 (back) a change of the active subframe is possible. The counter will be updated by the keys + or -.  
-All functions can be controlled over a popup menu. 
- 
-   
-Figure 30. Popup menu – right mouse button 
- 
-Press the button Reset counter in order to reset the counter of the active subframe. 
- 
-  
- 
-The total counter reading will be shown after reaching the last subframe. 
- 
- 
- 
-=====7.2 Calibrate===== 
- 
-With the help of this function the DPI parameters can be matched with the actual proportions. 
-This will be necessary for instance if the magnification factor of a digital camera is unknown. An image containing a scale is needed here (see figure 31).
