"Image buffer size > 1" setting
With image buffer sizes greater than 1, intermediate buffering takes place between image
acquisition and processing and between processing and result output. In other words: Image
acquisition can at times be performed in a faster sequence and processing can also buffer
results briefly prior to transfer. This allows brief periods of peak load to be handled.
