3.4.2.3 Guidelines When Using Free-run
When using free-run mode to control exposure, several general guidelines must be followed:
• The line period must not be lower than a defined minimum. The minimum line period for each
camera version is shown in Table 3-4.
• In the free-run programmable mode, the minimum and the maximum exposure time must be
within the limits specified in the Exposure Time CSR (see page 4-14 ).
• When you are operating the camera in free-run, using the edge-controlled mode will give you
the best performance in terms of signal-to-noise ratio.
3.5 Integrate Enabled Signal
An output signal called Integrate Enabled (IntEn) is available on
L800
k
cameras. The integrate
enabled signal indicates that an exposure is taking place. The signal will go high when each
exposure begins and go low when the exposure ends. The characteristics of the signal are
described in more detail in Section
2.5.6 .

We strongly recommend using an exposure time that is at least 10% of the
line period. Exposure times shorter than 10% of the line period will increase
the non-linearity of the camera’s response.
