controlling and adjusting the line scan cameras,

Synchronization
To obtain a proportional image with the correct aspect
ratio, a line synchronous transport with the laterally correct
pixel assignment is required. The
Line frequency
and
constant object velocity have to be compatible with each
other.
For more accurate requirements or with a variable object
velocity, external synchronization is necessary.

Thresholding (monochrome cameras only)
The thresholding process generates a binary signal from
the gray scale data, with values below the threshold
yielding 0 and those above yielding 1. Only the pixel
addresses of the location and threshold transition (from
high
→
low or low
→
high) are transmitted, reducing data
throughput.
Thresholding is particularly appropriate for measuring
widths or edge positions, by simply masking the required
pixel addresses.
