Overview
Overview
The XC-HR90 is a black-and-white video camera
module using a CCD (Charge Coupled Device) image
sensor.
Features
High image quality
The 1,300,000-pixel SXGA-compatible CCD image
sensor delivers detailed images with the equivalent of
SXGA resolution (1280 ×960 pixels). The CCD has
square pixels, eliminating the need for aspect ratio
conversion.
Various mode settings
Rear panel switches, or sending a command from the
host device (e.g., PC) allow the following mode
settings.
•Gain: Fixed/Manual
•Read mode (30 fps): Normal (30 fps)/Binning
(54.1fps)
•Read mode (15 fps): Normal (15 fps)/Binning (30fps)
•Partial scan
•Synchronized input/output
•75Ωtermination
•Shutter modes: Normal/Trigger shutter
•Shutter speed
External synchronization
The camera module automatically detects HD
(horizontal drive) and VD (vertical drive) signals input
for external synchronization.
External sync signal output
You can output HD and VD signals from a 12-pin
connector by changing the setting of a rear panel
switch.
Electronic shutter
You can choose a shutter speed from a wide range of
image speeds (1/100 to 1/100,000 s) for the best match
to shooting conditions.
External trigger shutter function (1/4 to
1/100,000 s)
You can obtain a freeze picture by inputting an
external trigger. This function is useful for shooting a
fast-moving object at a precise moment.
Partial scan
By limiting the number of effective image output lines,
you can obtain image output at high frame rates,
suitable for high-speed image processing.
Binning function
Video signals combining vertically adjacent lines can
be obtained at following frame rate.
In read mode (30 fps): 54.1 fps
In read mode (15 fps): 30 fps
Mounting holes
Mounting screw holes are provided on the reference
plane on the lower surface of the body, allowing
mounting for minimum deviation in the optical axis.
Compliant with EIAJ 12-pin connector pin
assignments
The pin arrangement adds pin assignments for trigger
pulses and WEN signals.

1VIDEO OUT/DC IN/SYNC (video output/DC
power/sync input signal) connector (12-pin
connector)
Connect a CCXC-12P05N camera cable to this
connector to obtain power from the +12V DC power
supply and also to enable video signal output from the
camera module. When a sync signal generator is
connected to this connector, the camera module is
synchronized with the external sync signals (HD/VD
signals).
2M GAIN (Manual Gain) control knob
If you have selected MANUAL (manual adjustment)
with DIP switch 4, this knob adjusts the gain.
3Shutter speed/Mode setting DIP switches
1Shutter speed (Switches 1 to 4)
Set an appropriate shutter speed (factory setting:
OFF).
2Partial scan mode switch (Switch 5)
The factory setting of this switch is partial scan
OFF.
For more information, see “Partial Scan Mode”
(page 20).
3Restart reset/External trigger shutter mode
switches (Switches 6 to 8)
By inputting an external restart/reset signal, you
can capture the information of single screens at
arbitrary timing. By inputting an external trigger
signal, you can capture imaging information on
fast-moving objects at a precise moment in
time. The factory settings for these switches are
for normal operation.
For more information, see “Restart/Reset” (page 19)
and “External Trigger Shutter” (page 22).
4Gain switch (Switch 9)
This switch selects FIX (fixed) or MANUAL
(manual adjustment) (factory setting: FIX (left
side)).
5Binning mode switch (Switch 0)
Switches the video signal output mode between
binning OFF and binning ON (factory setting:
OFF).
For more information, see “Video Output Modes”
(page 14).

Overview
2HD/VD signal input/output switch
Set this switch to the down position when an
HD/VD signal is output from the camera
module. Set this switch to the up position when
an HD/VD signal is input from an external unit
(factory setting).
Note
Even when the switch is set to the up position,
the camera module operates in internal
synchronization mode when no external HD
signal is input. In this case, however, the camera
module will not output internal sync signals.
830 fps/15 fps switch
This switch selects the frame rate.
30 fps: Set this switch to the down position
(factory setting).
15 fps: Set this switch to the up position.
9RS-232C ON/OFF switch
This switch selects whether or not you control
the camera module via the RS-232C serial
interface.
RS-232C ON: Set this switch to the up
position.
RS-232C OFF: Set this switch to the down
position (factory setting).

Overview
Camera Control Method
You can control the camera module from host device
such as a PC. The following table shows the control
functions. You can send a command corresponding to
the control items, with parameters for the desired
setting, if necessary, from the host device to control
the camera.

above) to 1/100000

Frame rate 30 fps/15 fps
Notes
•Make sure to supply power to the camera module and
confirm that the camera module is operating before
inputting a sync or trigger signal. If you input
external signals to a camera module without the
power supplied, this may cause malfunction of the
camera module.
•Be sure to turn off the power of the camera before
changing the settings of the RS-232C ON/OFF switch
and the 30 fps/15 fps switch.
IMPORTANT
When you control the camera using both an external
synchronous signal and the host device (e.g., a PC), be
sure to use the camera within the specified frequency
range. If the camera receives signals in frequencies
other than the specified one, the camera cannot be
controlled.

10
Mode Settings
Note that input outside the specified ranges can lead to
internal reset instability and malfunction of the RS-
232C communication.
However, when you input an external HD/VD phase
signal in all modes, the video out signals are output
about 1 H later than the external VD.
During normal operation (30 fps mode)
HD phase: 33.67 µ sec/37.32 µ sec (binning OFF/ON)
VD phase: 33.33 m sec/18.47 m sec (binning OFF/
ON)
During normal operation (15 fps mode)
HD phase: 67.34 µ sec
VD phase: 66.66 m sec/33.33 m sec (binning OFF/
ON) continuous
During restart/reset or external trigger shutter
mode operation
HD phase: 33.67 µ sec (30 fps normal), 37.32 µ sec
(30 fps binning), 67.34 µ sec (15 fps normal/
binning) continuous
VD phase: VD (reset) only timing where the HD
phase is within range shown above.
Mode Settings
It is recommended that you make a test under the
conditions you will operate the camera before actually
using it.

Setting Restart/Reset Mode
The information on one screen can be extracted at
any time by externally inputting restart/reset signals
(HD/VD). To enter this mode, set the trigger shutter
switches (6 to 8) on the rear panel of the camera as
shown in the figure below.
To use restart/reset mode and partial scan mode
simultaneously, set the partial scan mode switch (5)
to ON (right side).
Long exposure
The Restart/Reset function extends the CCD
accumulation time, resulting in highly sensitive
image capture. This function is effective when you
cannot gain satisfactory sensitivity under normal
operating conditions, or when you want to observe
the trail of a moving object. Extend the VD interval
(T) between external VD pulses.

Partial Scan Mode
You can increase the frame rate by setting the upper
high-speed transfer (FPS) and the lower high-speed
transfer (RPS) via the RS-232C interface. When the
RS-232C ON/OFF switch is set to OFF, you can set
the 1/2 partial scan mode or 1/4 partial scan mode by a
combination of switch 5 and switch 10 located on the
rear panel.

Notes
•In trigger shutter mode, video out signals are output
about 1 H later than the external VD.
•In partial scan mode, image output and the WEN
rising edge are always synchronized, but the WEN
width becomes undefined.
