Piranha4 4K and 2K Dual Line Monochrome CMOS Camera User's Manual 35
Teledyne DALSA 03-032-20176-02
Sensitivity Modes and Pixel Readout
The camera has the option to operate in either TDI mode or single line mode. When in TDI mode, the
camera uses both line scan sensors and as a result the responsivity increases (57%). When in single line
mode, the camera uses the bottom sensor only. The internal gain is 1.27x greater for single line mode vs.
TDI mode.
Figure 17: TDI Mode Examples
In TDI mode, the camera uses a 10.56 µm x 10.56 µm pixel and captures the same image twice, resulting
in a brighter image.
Figure 18: Single Line Mode Examples
In single line mode, the camera uses a 10.56 µm x 10.56 µm pixel and captures the image using one sensor
(Sensor 1).
