Function Parameter
This section takes on the functions of the industrial camera.
Industrial cameras support 3 user levels, including
Beginner
,
Expert
and
Guru
. Each
corresponds to slightly different sets of parameters.
Grayed out parameters cannot be changed under the current running mode.
Frame Rate
3.1
Frame rate, in area scan cameras, is the number of images the camera outputs every second.
3.1.1
Influential Facts for Frame Rate
Bandwidth: The bigger the bandwidth, the bigger the transmission data volume and the
higher the frame rate.
Pixel format: Different pixel formats takes up different amount of storage. Under the same
environment, the more storage is occupied, the lower the frame rate becomes.
Image resolution: Relates to the camera sensor features, affected by the image size as well.
With the smaller image size, the frame rate gets higher.
Exposure time: The longer the exposure time, the lower the frame rate and vice versa.
3.1.2
Configuring Frame Rate
AcquisitionFrameRateEnable
is the parameter for enabling frame rate acquisition.
True
means enable and
False
means disable.
Configure frame rate
Figure 3-1
AcquisitionFrameRate
defines capture rate of frames.
ResultingFrameRateAbs
defines the largest speed of capturing frames allowed.
When the value of
AcquisitionFrameRate
exceeds that of
ResultingFrameRateAbs
, the camera
captures images at the frame rate of
ResultingFrameRateAbs
value. Opposite of that, the camera
captures images at the frame rate of
AcquisitionFrameRate
value.
