Optimizing performance
Frame rate jitter
Affected models:
Alvium 1800 U-120m/c, U-500m/c, U-501m NIR, and
U-2050m/c
Generally, some parameters can be changed during exposure without affecting the
timing. When the camera is operated in freerun mode without triggering, changing
parameters during exposure leads to a frame rate jitter.
When parameters are entered, the next frame starts only after readout and sensor
reconfiguration delay are finished. When the camera is run in
ExposureAuto
mode, the actual frame rate is less than the calculated value for the corresponding
exposure time. Consider frame rate jitter for your application.
