9-6 TIMING CHART OF CAMERA OPERATION MODES
9-6-1 FREE RUNNING MODE
The camera has the free running mode which the exposure and readout timing can be set by
software command and controlled by an internal microprocessor. The free running mode has
normal readout mode (in which the exposure time is longer than the 1 frame readout time) and
electrical shutter mode (in which the exposure time is shorter than the 1 frame readout time).
These readout modes are automatically switched depending on the exposure time setting.

Please contact to Hamamatsu subsidiary or local distributor for the detail of the timing
information.
9-6-1-1 Normal readout mode
The normal readout mode is suitable for observation, monitoring, field of view and focus
adjustment, and animation because it can operate with full resolution, which is faster than the
video rate (30 frame/s).
In addition, the exposure time can be extended to collect more signals and increase the
signal-to-noise ratio if the object is dark. In the normal readout mode, the exposure time is the
same or longer than the 1 frame readout time. In this mode, the frame rate depends on the
exposure time, and it becomes frame rate = 1/exposure time. The maximum exposure time is 10
s.
