8.10.9 High resolution line period
High-Resolution Line period is a read-only property which shows the actual value of line period that
is congured into the sensor. When the exposure time approach to expected line period (or become
longer), line period needs to be incremented by the given amount of time the sensor requires to perform
the acquisition.
Example Code 8.24 | Get the high resolution line period
float actualLinePeriod = device.HighResLinePeriod;
8.10.10 Analog Gain
The Gain control adjusts the gain of the analog section of the sensor; it allows to adjust the analog sen-
sitivity to compensate for insufcient lighting.
(a) Gain 0 (base value) (b) Gain 7
Figure 8.17: Example of Gain control effect.
Warning
To maximize the signal-to-noise ratio (SNR) of the acquisition, it is recom-
mended to choose a lighting system that allows using the lowest possible
Gain values.
Note
The sensor’s analog gain is slightly dependent on the selected ADC resolu-
tion; the same Gain value may therefore generate slightly different gain lev-
els when operating at different ADC resolution. You should set the operating
ADC resolution before choosing the Gain level required by the application.
