4. OVERVIEW
The C9300-201 is a small size and high performance digital CCD camera with 12 bit output.
The camera meets the demand in the industrial/scientific field for high accuracy and high
quality imaging. And it is based on CameraLink and can output the image data into the
CameraLink board on market.
5. FEATURES
(1) High speed
Equipped with a high-speed solid-state imaging device having 640 (horizontal) × 480
(vertical) pixels. Pixels are square, facilitating image processing for measurement
purposes.
(2) Dual readout
The CCD has dual readout amplifiers for the half left side area of the CCD and right
side. (When using single readout mode, only left side amplifier is used.) So you can
obtain the image data with quite high frame rate.
Note • Dual readout mode uses two-separated readout Amp whose performance is not
perfectly same. Due to the readout Amp characteristics variation, you may see
little intensity gap between right side and left side in one image even though the
fine adjustment is done at factory before shipping. Single readout mode is
recommended to achieve the best possible image quality.
(3) Digital output
Image signals are converted from analog to digital in the camera and output externally
as 12 bit digital data. (Transmission line length: max. 10 m, based on CameraLink.)
(4) Small Head
Small, lightweight camera allows for a construction that is extremely easy to use in
such applications as microscopic measurement and spectrometry.
(5) Lens mount
C-mount used for the lens mount.

9. IMAGE ACQUISITION
9-1 THEORY OF CCD
The all-pixel-readout interline transfer CCD used in this camera is arranged as shown in
Figure 9-1. Incident light at the CCD is converted by photosensors to electrical charges
which are transmitted through a shielded vertical transfer CCD (VCCD) and a horizontal
transfer CCD (HCCD) to a final output charge-voltage conversion amp. The sensor gate is
opened by the readout signal, and the charges generated by all of the photosensors are
transmitted unmixed to the VCCD, completing the exposure.
In addition, an electronic shutter signal is applied to the CCD, allowing any accumulated
charge in the photosensors to be discharged.

● Binning
Accumulated charges for a specified number of pixels in the vertical and horizontal directions
on the CCD are calculated and combined (binned), then readout from the CCD. With this
camera, binning can be set to 2×2, where two pixels in the vertical and horizontal directions are
combined, 4×4, where four vertical and horizontal pixels are combined, or 8×8, where eight
vertical and horizontal pixels are combined.
● Exposure Time
When set to the normal CCD scanning mode, this is as shown in Figure 9-2.Exposure time is
the elapsed time between one readout signal and the next; this interval is at least as long as
the time necessary for all of the charges from the CCD to be readout.
● Dual readout
The CCD has dual readout amplifiers for the half left side area of the CCD and right side as
shown in Figure 9-1. When using single readout mode, only left side amplifier is used. And
when using dual readout mode, these two amplifiers are used at the same time for readout, so
you can obtain the image data with quite high frame rate.

9-2 OVERVIEW OF 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 two categories below.
(1) Free running mode
Exposure and readout is performed repeatedly, controlled by the internal microprocessor.
Some operations for which the commands can be used are shown below.
CCD output mode Single/Dual
Scan mode Normal/Binning/Sub-array/Line scan
Exposure time settings Normal /Electronic Shutter/Absolute Time
Digital data output bit count 12 bit/10 bit/8 bit
(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. In addition, commands can be used the following.
CCD output mode Single/Dual
Scan mode Normal/Binning/Sub-array/Line scan
Exposure time settings Internal (Electronic Shutter or Absolute Time)/External
Digital data output bit count 12 bit/10 bit/8 bit
External control pulse polarity Negative/Positive

Note • Dual readout mode uses two-separated readout Amp whose performance is
not perfectly same. Due to the readout Amp characteristics variation, you
may see little intensity gap between right side and left side in one image
even though the fine adjustment is done at factory before shipping. Single
readout mode is recommended to achieve the best possible image quality.
9-3-3 DETAIL ON CCD SCANNING (SCAN MODE)
Select either normal readout or binning readout.
(1) Normal readout [SMD N]
Electrical charges from the CCD are readout in the normal, standard scanning. The
time required for CCD readout of all of the CCD’s pixels is approximately 12.2 ms at
single output mode and 6.7 ms at dual output mode.
(2) 2×2 binning readout [SMD S, SPX 2]
Electrical charges from the CCD are readout in 2×2 binning. The time required for CCD
readout of all of the CCD’s pixels is approximately 6.5 ms at single output mode and
3.7 ms at dual output mode.
(3) 4×4 binning readout [SMD S, SPX 4]
Electrical charges from the CCD are readout in 4×4 binning. The time required for CCD
readout of all of the CCD’s pixels is approximately 3.6 ms at single output mode and
2.2 ms at dual output mode.
(4) 8×8 binning readout [SMD S, SPX 8]
Electrical charges from the CCD are readout in 4×4 binning. The time required for CCD
readout of all of the CCD’s pixels is approximately 2.2 ms at single output mode and
1.5 ms at dual output mode.
(5) Sub-array readout [SMD A]
In this mode, only a required area is readout at the normal speed while the remaining
areas are rapidly cleared. This operation allows the frame rate to be increased.
(6) Line scan readout [SMD L]
In this mode, only a required area is readout at the normal speed while the remaining
lines are rapidly cleared. This operation allows the frame rate to be increased.

(3) Exposure time setting: Absolute Time [NMD T, AET ss.xxx]
Exposure and readout repeat along with the operation of the electronic shutter
according to the sequence set internally. The exposure time is set with the AET ss.xxx
command (where s = seconds, x = milliseconds). The actual length of exposure time is
the specified time taken as a value expressed in horizontal scan units. Exposure time
longer than 1 s is not possible.

9-3-4-2 External control mode [AMD E]
The external trigger pulse is input via the timing I/O connector on the rear panel and the polarity
is selected from “N” (negative: Low-level active) or “P” (positive: High-level active). The external
trigger pulse should be TTL level and the minimum active period is 1 µs and the repeat cycle
must match the selected mode.
Note • Images are not output correctly if the pulse input is shorter than 1 µs.
The following text describes the external control mode with the external trigger pulse polarity
set to “N” (negative). If “P” (positive) is selected, the rise and fall of each pulse is reversed
(inverted), with the LO interval becoming the HI interval. Descriptions enclosed in brackets ({ })
indicate cases where “P” (positive) is selected.
(1) Exposure time setting: Internal / Electronic Shutter [EMD E, EST n]
Exposure begins within 2 μs from the fall {rise} of the external trigger pulse, the
exposure is made using the time set with the EST n command, and readout follows.
After readout, the system waits for the external trigger pulse to fall {rise} again. The
exposure time is set with the EST n command. This setting is made in units of one
horizontal scan cycle. The repeat cycle is controlled by the external control pulse's
repeat cycle, but the minimum cycle is calculated as shown below. Set the external
control pulse's repeat cycle so that it is longer than the minimum cycle.
Minimum repetition time = readout time + set exposure time
