Operating Modes
6.1.1
Freerun Mode
In freerun mode, the camera sensor captures one image after another at the set frame rate.
Exposure and readout/transfer of the image data are performed in parallel. This allows the maximum
camera frame rate to be achieved. The frame rate and the exposure time can be set separately. The
captured images can be transferred one by one or continuously to the PC.
If trigger mode is active, you need to disable it before activating freerun mode.
·
Single frame mode (snap mode)
The next image exposed by the sensor will be transferred. You cannot use the
uEye
flash outputs
in this mode.
·
Continuous mode (live mode)
Images are captured and transferred continuously. You can use the
uEye
flash outputs.
The following illustrations show a schematic view of the image capture sequence. The
sensor exposure and readout times and the transmission times depend on the camera
settings. The pre-processing time depends on the API functions you are using (e.g. color
conversion, edge enhancement).
