Settings Behavior During Startup - Matrix Vision mvBlueLYNX-X Technical Manual

To see the true maximum rate of data acquisition turn off the display in wxPropView completely. You will
notice that the camera is able to capture vast amounts of data at a very high rate with very little CPU load - it
is the display which costs CPU power.

12.4.1 Settings behavior during startup

Settings contain all the parameters that are needed to prepare and program the device for the image capture.
Every image can be captured with completely different set of parameters. In almost every case, these
parameters are accessible via a property offered by the device driver. A setting e.g. might contain
• the gain to be applied to the analog to digital conversion process for analog video sources or
• the AOI to be captured from the incoming image data.
So for the user a setting is the one an only place where all the necessary modifications can be applied to
achieve the desired form of data acquisition.
Now, whenever a device is opened, the driver will execute following procedure:
Each setting location step in the figure from above internally contains to search steps. First the
framework will try to locate a setting in the current local directory.
Whenever storing a product specific setting, the device specific setting of the device used for storing
will be deleted (if existing). So when the user is currently working with a device LX000001 belonging
to the product group mvBlueLYNX-X and there is a setting exclusively for this device storing a
product specific setting now will automatically delete the setting for LX000001. Otherwise a product
specific setting would never be loaded as a device specific setting will always be found first.
That the very same thing will also happen when opening a device from any other application!
wxPropView does not behave in a special way but only acts as an arbitrary user application.
