9. IMAGE ACQUISITION
This section describes the modes required when using the camera to obtain images.
9-1 OVERVIEW OF THE CAMERA MODES
This camera features many different operational modes. Furthermore, all modes involve the
CameraLink interface's built-in microprocessor, providing control and setting for all modes.
Of the numerous different modes, the modes used for obtaining images are broadly
classified into the categories below.
(1) Internal control mode
Exposure and readout is performed repeatedly, controlled by the internal
microprocessor. Some operations for which the commands can be used are shown
below.
Scan modes Normal readout/Binning readout/Sub-array readout
Exposure time setting Norma/Frame blanking
(2) External control mode
An external control (trigger) pulse input the internal microprocessor and the
repeating exposure and readout. Exposure start timing and length of exposure can
be controlled with the external trigger pulse. Some operations for which the
commands can be used are shown below. It includes two modes, Edge trigger
mode*
1
and Level trigger mode*
2
.
Scan modes Normal readout/Binning readout/Sub-array readout
External control pulse polarity Negative/Positive

1 The camera is stand-by and waits for external trigger input when the camera is set in this mode. When the external
trigger signal is input, Electrical charges generated in CCD before the external trigger signal input is dumped out by
High-speed readout. After that, the camera starts the accumulation of the electrical charge until the end of the
exposure time, readout charged electrons and output digital data. The exposure time can be set by the command
operations.

of the external trigger.

9-2-1 BINNING READOUT AND BINNING SETTINGS VALUES
In addition to the normal readout (1×1 binning readout), in which the digital output pixel
count is read out as is, the following readouts are available.
Binning Commands
2×2 binning readout: 2 horizontal pixels combined with 2 vertical pixels.
SMD S SPX 2
4×4 binning readout: 4 horizontal pixels combined with 4 vertical pixels.
SMD S SPX 4
8×8 binning readout: 8 horizontal pixels combined with 8 vertical pixels.
SMD S SPX 8
16×16 binning readout: 16 horizontal pixels combined with 16 vertical pixels.
