18.2.6 Using the linescan mode
Both CMOS sensors from e2v offer a linescan mode. One (gray scale sensor) or two lines (in terms
of color sensor) can be selected to be read out of the full line height of 1024 or 1200 lines. This or
these lines are grouped to a pseudo frame of selectable height in the internal buffer of the camera.
Complete instructions for using the linescan mode are provided here:

18.2.6.2 Initial situation and settings
Generally, linescan cameras are suitable for inspections of moving, continuous materials. In order
that the linescan camera acquires the line at the right time, an incremental encoder, for example, at
a conveyor belt triggers the linescan camera. Normally, an incremental encoder does this using a
specific frequency like 1:1 which means that there is a signal for every line. However, during the
adjustment of a line trigger application or while choosing a specific incremental encoder you have to
keep the specific frequency in mind.
Note:
Using timers and counters it is possible to skip trigger signals.
In linescan mode, the camera adds the single lines to one image of the height of max. 1024 or 1200
lines (according to the used sensor). The images are provided with no gap.
Note:
While using the linescan mode with a gray scale sensor, one trigger signal will lead to one
acquired image line. Using a color sensor, one trigger signal will lead to two acquired image
lines.
Due to aberrations at the edges of the lens, you should set an offset in the direction of Y ("Offset
Y", see the following figure), generally around the half of the sensor's height (a.k.a. sensor's Y
center). With Offset Y you can adjust the scan line in the direction of motion.
