Multi-Exposure Mode
The multi-exposure mode allows for the simultaneous exposure of each line of the sensor with two
different exposure times or gains. The result is an increase in the dynamic range of the image.
Note: to initiate multi-exposure mode, set TDI stage = 1 (stg 1) and ensure that the camera is in line scan
mode (dst 0). The exposure time selector (ses) command is used to select which line to apply the
exposure time.
In the above example image the left and right half side of the image are identical except for the amount of
exposure time applied.
