COE LS-X Line Scan Camera | USER MANUAL
⚫
When switching
TDI Mode
, the camera may have a short period (3 s to 5 s) of image corruption,
which is a normal phenomenon.
TDI refers to Time Delay Integration, and it is a method of line scanning which provides dramatically
increased responsivity compared to other video scanning methods. It allows for much greater
scanning speeds in low light, or allows reduced lighting levels (and costs) at conventional speeds.
In general, there are 3 TDI modes, including 1 line, 2-TDI and 4-TDI.
⚫
1 line refers to single line mode, and the camera selects 1 line data as output result.
⚫
2-TDI means that the camera overlaps 2 adjacent line data, and outputs 1 line data as final
result.
⚫
4-TDI means that the camera overlaps 4-line data, and outputs 1 line data as final result.

11.4 Scan Direction
⚫
The scan direction function may differ by camera models.
⚫
Make sure that the scan direction and the moving direction of objects are matched. Otherwise,
acquired images may be abnormal.
The scan direction function is used to change the scan direction of the sensor used on measured
objects. After selecting
TDI Mode
, you can go to
