TIMING CHART OF CAMERA OPERATION MODES

9-6-1

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.

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
