Mirror lock-up (MLU) is a feature available in some SLR cameras which aims to minimize camera shake induced by mirror-slap (which produces the characteristic snapping sound of SLR cameras).
As an attempt in this paper, the available related judgment parameters are found based on the systematical analysis of characteristic curves of flow dynamic axis, bank line and levee line.
