7.3 Power saving Mechanisms
The camera is equipped with various power saving mechanisms to reduce the power
consumption and to prevent excessive heating.
1. Set the sensor into idle state
If no frame is requested for a specific time (idle time), the sensor is set into idle state. This
reduces the power consumption of the camera.
The sensor is not set into idle state:
▪ in Sequencer Mode
▪ in Burst Mode
▪ at set Acquisition Frame Rate

2. Dynamic adjustment of the framerate
The frame rate is dynamically adjusted to the current situation. This means that only so
many frames are recorded, as can be transferred via the interface with the current set-
tings (e.g. resolution, binning and pixel format).
This dynamic adjustment only works when the feature
Acquisition Frame Rat
e is deacti-
vated, so the camera takes pictures at FreeRunning Mode.

Notice
The diagram applies for a low exposure time. As the exposure time increases, the pow-
er consumption of the camera increases even with small framerate.
