8.3.8. Device User ID
The MER-U3 series camera provides programmable device user ID function, the user can set a unique
identification for the camera, and can open and control the camera by the unique identification.
The user-defined name is a string which maximum length is 64 bytes, the user can set it by the following
ways:
1) Set by the GalxyView, as shown in the Figure 8-31.
Figure 8-31 DeviceUserID
2) Set by calling the software interface, for details please see the Programmer's Guide.
When using multi-cameras at the same time, it is necessary to ensure the uniqueness of the
user-defined name of each camera, otherwise, an exception will occur when the camera is
opened.
8.3.9. Timestamp
The timestamp feature counts the number of ticks generated by the camera's internal device clock. As
soon as the camera is powered on, it starts generating and counting clock ticks. The counter is reset to 0
whenever the camera is powered off and on again. Some of the camera's features use timestamp values,
such as frame information, and timestamps can be used to test the time spent on some of the camera's
operations.
The unit of timestamp is ns.
8.3.10. Binning
The feature of Binning is to combine multiple pixels adjacent to each other in the sensor into a single value,
and process the average value of multiple pixels or sum the multiple pixel values, which may increase the
signal-to-noise ratio or the camera's response to light.
