How to use ToupView software's real-time EDF function

The real-time EDF function in ToupView software allows real-time extended depth of field in video mode. When the depth of field is shallow and the specimen has a certain thickness, EDF helps build images that focus as accurately as possible on all parts. Real-time EDF means that the real-time results of the EDF function can be updated immediately during the EDF process, and users can adjust the process according to the real-time results. Automatic alignment is applied during operation to achieve optimal performance in case of slight FOV (field of view) offset.

• Click the camera name in the camera list to get video.
• Click the EDF button in the toolbar to open the real-time EDF window.

• The real-time EDF window will display as follows. The left window is the real-time preview window of the camera, and the right window is the real-time EDF result.

• Adjust the position of the specimen in Z order. The real-time preview of the specimen will be displayed in the left video window. The EDF result will be updated in real-time in the right window.

• Click the EDF button again to stop the real-time EDF function.

Notes:

• Settings related to real-time EDF are integrated in the "Preferences" settings, as shown in the following snapshot.

• Real-time EDF provides three methods, including "Maximum Contrast" method, "Weighted Average" method, and "Stacking" method. The "Maximum Contrast" method is the default method.
• It is best to disable auto-exposure during this process.
• The real-time preview window size can be changed from 10% to 40%, and the EDF result window size can be easily adjusted by the mouse middle button or zoom settings in the toolbar.
