Multi-Exposure Output Format
While in multi-exposure mode the width of the output will double. An 8k camera will output a 16k
image. The same line is outputted twice with each line a different exposure—the left half of the image
being the bottom line and the right half being the top line.
Output AOI when in Multi-Exposure Mode
The same output AOI will be applied to both the top and bottom lines while in multi-exposure mode.
Line Rate
While in multi-exposure mode the maximum line rate available is limited by the longest exposure time.
Exposure Time Limitation
The exposure time of the two lines must differ by greater than 1 µs.
Digital I/O Control Feature Descriptions
The P4 Digital I/O controls, as shown by CamExpert, groups sensor specific parameters. This group
includes controls for line rate, exposure time, scan direction, and gain. Parameters in gray are read only,
either always or due to another parameter being disabled. Parameters in black are user set in CamExpert
or programmable via an imaging application.
