User Data Area
The user data area is a FLASH data area reserved for the user, and the user can use the area to save
algorithm factors, parameter configurations, etc.
The user data area is 16K bytes and is divided into 4 data segments, each of which is 4K bytes. The user
can access the user data area through the API interface. The data is saved to the camera flash area
immediately after being written, and the data will not disappear after the camera is powered off.

Frame Period
You can calculate the frame period of the VEN-U3 series camera by the following formula:
𝑇

𝑇
𝑓
: The camera's frame period, unit: μs.
