6.11. Partial scan readout mode
This mode allows increased frame rate, as only a selected number of lines are read out. The vertical resolution is reduced as outlined below. Partial scan will operate in normal continuous mode and all trigger modes.
Fig. 23. Partial scanning.
The partial scanning settings are as follows:
Readout format | Frame rate | Effective lines | |
Full frame readout | 30 fps | 492 | SC=0 |
1/2 partial readout | 58 fps | 240 | SC=1 |
1/3 partial readout | 73 fps | 160 | SC=2 |
1/6 partial readout | 124 fps | 80 | SC=3 |
To use this mode: |
|
|
Set function: | Trigger mode to any | TR=0 through TR=6 |
| Shutter mode to “Normal” or “Programmable” | SM=0, SM=1 |
| Shutter Speed using fixed steps | SH=0 through 7 |
| or Programmable exposure | PE=1 through 1023 |
| Polarity and other functions |
|
Input: | Ext. trigger to pin 5 on 6 pin connector (or 11 on 12 pin connector) | |
| Ext. VD to pin 7 on 12 pin connector. |
|
| Ext. HD to pin 6 on 12 pin connector. (If used). |
|
Important notes on using this mode:-
•In order to minimize smear effects on the image, it is recommended to avoid strong light outside the active partial scanned region.
