Chapter 7 Image Acquisition

7.1 Set Line Rate

Line rate refers to the image line number that is output by the camera per second. The following 4
factors determine the maximum line rate:
 Readout time: The less the readout time and the higher the line rate will be.
 Exposure time: The less the exposure time, the higher the line rate will be.
 Bandwidth (here refers to Camera Link configuration mode): The larger the bandwidth, the
higher the line rate will be.
 Pixel format: The more bytes pixel format occupy, the lower the line rate will be.
The frame rate of the camera is proportional to the line rate, and is inversely proportional to the
height of the image area, that is, Fps=Lps/Image Height.
In client software, click Acquisition Control > Acquisition Line Rate (Hz), enter Acquisition Line
Rate (Hz), and enable Acquisition Line Rate Control Enable. You can view real-time line rate and
frame rate in Resulting Line Rate (Hz) and Resulting Frame Rate (Hz) respectively.

7.2 Set Scan Mode

The scan mode function may differ by camera models.
The scan mode decides that how the camera reads the image data, and it includes frame scan and
line scan. If Line Scan is selected as Scan Mode, the camera is a pure line scan camera. Go to
Acquisition Control, and you can set Scan Mode according to actual demands.
