Accumulate
refers to an acquisition in which a number of frames in a series are accumulated together into a single
image. This accumulation of user frames is performed off-camera. Either all the user frames in a series are accumulated
to give a single accumulated image or a smaller number of user frames in the series are accumulated to give a series of
accumulated images.

Run Till Abort
refers to an acquisition in which an infinite number of user frames can be transmitted from the camera
and the acquisition will continue to run until it is aborted.
One user frame will be output from the sensor on receipt of each valid trigger of the selected type. All valid triggers will
output another user frame from the sensor. Frames are transmitted from the camera in as quick succession as possible.

Live Mode
refers to a version of Run Till Abort in which each user frame will be the latest frame output by the sensor and
will have the minimum amount of latency through the camera as possible.
Live mode requires the use of SW Trigger. In order to ensure that frames are buffered in the on-camera memory for the
shortest possible time, the next SW trigger must not be sent until the user frame has been transmitted from the camera.
This ensures that the on-camera memory only stores a single user frame at a time and no additional latency builds up.
NOTE: The frame rate achievable in Live Mode is dependent on the performance of the system that the camera is
attached to.

During an acquisition the user can change the exposure time, within allowable limits. Once a new exposure value has
been written, it will be applied to the next user frame after the current frame exposure has completed. The exposure time
can be changed any number of times before the acquisition finishes.

If Internal Trigger is being used, the camera will trigger the sensor at the fastest possible rate by default. The user can
reduce this trigger rate by defining a frame rate that is less than the maximum possible rate. Frame rate must be set
before the acquisition starts.
