Operation
5.2.7 ICU-1 (Iris Control Unit)
The ICU constantly monitors the frame rate of the camera.
If a frame rate change occurs, the ICU will calculate a new
value for the iris to compensate for the exposure change,
and instruct the lens motor to change the iris ring accordingly.
Iris changes are calculated and set in such short time
intervals that all changes are smooth – even if the
camera’s frame rate is changing very slowly.
Speed Ramp Overview
A speed ramp is a change of the camera’s frame rate (fps),
performed while the camera is running. Speed ramps can
be used for a myriad of effects, from the dramatic speeding
up or slowing down of the action to the subtle enhancing
of a scene’s timing. A speed ramp essentially allows the
cameraman to compress or stretch time transparently and
dynamically.
