Alkeria NECTA Series - Line Period

8. Capturing Images 95
Note
The sensor’s analog gain slightly depends on the selected ADC resolution; the
same Gain value may therefore generate slightly different gain levels when
operating at different ADC resolution. You should set the operating ADC reso-
lution before choosing the Gain level required by the application.
Example Code 8.8 | Set ADC resolution to 10 bit
device.ADCResolution = 10;
Warning
It is possible to set ADC resolution only when camera is not acquiring.
Note
Changing ADC resolution involves automatic recomputing of the packet size
boundaries (see Section 8.9.4).
8.7 LINE PERIOD
The line period parameter controls the acquisition period, i.e. the time between the acquisition of two
lines.
Note
Dual line sensors expose the two rows simultaneously. Thus, line period is de-
ned as the time between the beginning of two consecutive exposures.
The line period control has effect only when the line trigger is disabled. Otherwise, the time between two
consecutive acquisitions is determined by the trigger frequency. NECTA provides two read-only vari-
ables reporting the allowed range (upper and lower limits) for the line period. The upper limit is constant
(100 ms), the lower limit depends on the parameters controlling the operating conditions and is calcu-
lated according to them; for example, any direct or indirect change of the packet size control involves
recomputing the minimum line period.
Unlike other video mode parameters, line period can also be modied during frame acquisition.
