7.1 Set Line Rate

Note
The image compression function may differ by device models. Refer to section Set Image
Compression Mode for details.
Line rate refers to the image line number that is output by the device per second. The
frame rate of the device is proportional to its line rate, and is inversely proportional to the
image height, that is, Fps = Lps (line rate)/Height (image height). The following five factors
determine the device's line rate in real-time.
● 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.
● Pixel format: The more bytes pixel format occupy, the lower the line rate will be.
● Bandwidth: The larger the bandwidth, the higher the line rate will be.
● Image compression mode: This function is used to compress data before transmitting
to the PC, and increase the frame rate to some extent.
Steps
1. Go to Acquisition Control → Acquisition Line Rate(Hz), and enter Acquisition Line
Rate(Hz).
2. Enable Acquisition Line Rate Control Enable.
Note
● If the real-time line rate is smaller than the value you set, the device acquires images by
the real-time line rate.
● If the real-time line rate is larger than the value you set, the device acquires images by
the value you set.
