34 Piranha4 4K and 2K Dual Line Monochrome CMOS Camera User's Manual
03-032-20176-02 Teledyne DALSA
Note: By default, the user settings are set to the factory settings.
Default Setting
Either the Factory or one of the User settings can be used as the Default Setting by selecting the set in the
User Set Default Selector. The chosen set automatically becomes the default setting and is the set loaded
when the camera is reset of powered up.

TDI and Single Line Modes
You have the option to set the camera modes as either single line (where only the bottom sensor is used,
which results in lower sensitivity) or as TDI (where the pair of sensor lines is summed, which results in
higher sensitivity).
TDI Mode vs. Vertical Binning 2
TDI mode delays one line before summing so that each row images the same area. In the case of vertical
binning equal to 2, the rows image adjacent areas and are summed without separation delay. This action,
combined with horizontal binning equal to 2, results in a big pixel that has half the resolution but four
times the response compared to TDI stages = 1.
TDI Stage 2 vs. Vertical Binning
Vertical Binning and TDI Stage 2 are very similar in operation in that for both modes both lines of the
sensor are used and both lines are summed together. The difference is that in vertical binning both lines
are summed directly, while in TDI Stages 2 one line is delayed by one EXSYNC before being summed
with the other line. The result is a 20 µm tall pixel for vertical binning while TDI Stage 2 maintains the 10
µm pixel height.
There is no line rate difference between these two modes.
