CAMERA OPERATION MODES

The camera has the following operation modes.
(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.
(2) External trigger mode
The camera has various external trigger functions to synchronize the camera with the
external equipment. In the external trigger mode, the external equipment becomes a
master and the camera becomes a slave.
① Edge trigger mode
The edge trigger mode is used so that the exposure starts according to an external signal.
② Level trigger mode
The level trigger mode is used to control both exposure start timing and exposure time length
by inputting external trigger pulses.
③ Synchronous readout trigger mode
The synchronous readout trigger mode is used for continuous imaging when it is necessary to
control the exposure start timing of each frame from an external source. It is useful for confocal
microscopy.
(3) Start trigger mode
The start trigger mode is to start operating the camera by a trigger input for a
continuous imaging.
