Color exposure time guidelines
The cam eras have no lim itations on the com binations of the exp osu re tim es available for each color
excep t the m axim u m of 3 m s and the m inim u m of 7μs exp osu re tim es. Op erating the cam era w ith the
cond itions stated below w ill give op tim u m im age p erform ance. Op erating the cam era beyond the stated
lim its m ay be p ossible bu t cou ld com p rom ise im age qu ality.
P4-CC-04K ideal operating conditions
For op tim u m im age p erform ance the exp osu re tim e for Blu e shou ld be great than green or red by m ore
than 1μs.
P4-CC-02K trilinear ideal operating conditions
For op tim u m im age p erform ance all of tthe follow ing m u st be tru e
1.
Blu e ≥ Red by 1μs
2.
Blu e ≥ Green by 1μs or Green ≥ Blu e by 1μs
3.
Red ≥ Green by 1μs or Green ≥ Red by 1μs
P4-CC-02K quadlinear ideal operating conditions
For op tim u m im age p erform ance all of the follow ing m u st be tru e
1.
Blu e ≥ Red by 1μs
2.
Green ≥ Mono by 1μs
3.
Blu e ≥ Green by 1μs or Green ≥ Blu e by 1μs
4.
Blu e ≥ Mono by 1μs or Mono ≥ Blu e by 1μs
5.
Red ≥ Green by 1μs or Green ≥ Red by 1μs
6.
Red ≥ Mono by 1μs or Mono ≥ Red by 1μs
Set Line Rate
To set the camera’s line rate use the line rate p arameter, part of the Sensor Controls set. This feature can
only be u sed w hen the cam era is in Internal m od e —that is, w hen the start line trigger is d isabled (Trigger
Mod e Off).
Note
: The line rate m u st be less than 1 / (Exp osu re tim e + 1500ns). Entering a valu e that violates this
cond ition will return an error (“Invalid Parameter”). You mu st ad just these two p arameters in the correct
sequ ence to m aintain this cond ition.
