Performance and troubleshooting
Effects for the interdependent features
Changing one control's value affects other control's values, such as:
If:
Height
value is changed.
Then: Other values may be affected, such as for
AcquisitionFrameRate
and
ExposureTime
.
We recommend you to consider:
• The more features you adjust, the more current values deviate from previously
set values.
• The same effects that apply to
ExposureTime
, also apply to
AutoExposure
.
• To avoid readjustments, apply settings in the order shown in
Figure 89
.
Impact by other features
Exposure times and frame rates with Sony IMX rolling
shutter cameras
Alvium 1800 U-1240 m/c, and U-2050m/c
Generally, long exposure times result in low frame rates because one is roughly the
inverse of the other. With Alvium IMX RS cameras
• The range of available frame rates depends on the exposure time.
• The exposure time must be increased when low frame rates are used.
• The available range for frame rate values depends on the exposure time. If by
changing the exposure time, the previous frame rate is moved out of the
available range, the frame rate is adjusted automatically.
