② HYST
The filter block is followed by the hysteresis block. It requires the filtered exposure
readings to exceed a programmable threshold before the camera will respond.
This can prevent the camera from dithering back and forth between two different modes of
operation when the meter readings are near a boundary between the two modes.
However setting the hysteresis parameters too high can make the camera appear
unresponsive..
The filter and hysteresis blocks effectively control what scene changes the camera will
respond to. They can be set to make the camera effectively ignore changes that are too
fast or too small. If a change in meter reading is substantial enough to pass through these
two blocks, the camera will respond. Then it’s a question of how quickly the camera
will respond—which is the purpose of the next block.
③ Trans
The role of the transition block is to control the rate of the transition from old to new
camera settings.
They control how big a transition can be made from the current setting to the target setting
at each step.
Set to their maximum values, the camera can make the transition from old to new setting
in one step.
Though the transition is as fast as possible, it can appear very rough.
Smaller values for the transition properties make the transitions smoother but slower.
