Overview
Overview
The XC-HR50 is a black-and-white video camera
module using a CCD (Charge Coupled Device) image
sensor.
Features
High image quality
The 330,000-pixel VGA-compatible CCD image
sensor delivers detailed images with the equivalent of
VGA resolution (648 ×494 pixels). The CCD has
square pixels, eliminating the need for aspect ratio
conversion.
Various mode settings
Rear panel switches allow the following mode settings.
• Gain: Fixed/Manual
• Read mode: Normal (60 fps)/Bining (120 fps)
• High-rate scan
• Synchronized input/output
•75Ωtermination
• Shutter modes: Normal/Trigger shutter
• Shutter speed
External synchronization
The camera module automatically determines whether
to operate in interlace or non-interlace mode from 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 from FL (flickerless) mode and a wide
range of image speeds (1/125 to 1/30,000 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 clearly.
High-rate 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.
Bining function
Video signals combining vertically adjacent pixels can
be obtained at 120 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 new EIAJ 12-pin connector
pin assignments
The new pin arrangement adds pin assignments for
trigger pulses and WEN signals.

Note
Be sure to turn the power off before making switch
settings.
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).
2Shutter speed/Mode setting DIP switch
1Shutter speed (bits 1-4)
Set an appropriate shutter speed (factory setting:
OFF).
2High-rate scan mode switch (bit 5)
The factory setting of this switch is high-rate
scan OFF. If you turn this switch ON to use
high-rate scan mode, you also need to make
pulse rate settings.
For more information, see “To Use High-rate Scan
Mode (A) (page 14)” or “To Use High-rate Scan
Mode (B)” (page 18).
3Restart reset/External trigger shutter mode
switch (bits 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 fast-moving objects at
precise locations. The factory settings for these
switches are for normal operation (restart/reset
and external trigger shutter OFF).
For more information, see “Restart/Reset” (page 13)
and “External Trigger Shutter” (page 16).
4Gain switch (bit 9)
This switch selects FIX (fixed) or MANUAL

Mode Settings
Restart/Reset
To Set Restart/Reset Mode
This mode allows you to capture the information on
single screens 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 high-rate scan mode
simultaneously, set the high-rate 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.

Note
High-rate scan mode cannot be used while in external
trigger shutter mode 2.
There are two modes for the timing in which video
signals are obtained.
• Mode 1 (Non-reset mode)
In this mode, a video signal synchronized with a VD
signal is output after a trigger pulse is input.
–The video signal is synchronized with the external
VD signal when an external HD*/VD signal is
input.
–The video signal is synchronized with an internal
VD signal when no external HD*/VD signal is
input.
* External or internal synchronization is selected
automatically depending on the presence or absence
of external HD input.
• Mode 2 (Reset mode)
In this mode, an internal VD is reset, then a video
signal is output a certain period of time after trigger
pulse input.
(High-rate mode is
compatible with Mode 1
only.)

You can obtain an arbitrary shutter speed by setting the
trigger pulse width to the range of 2
µ sec to
250 msec.
Exposure time = Trigger pulse width + 6 µ sec
Note
An incorrect video signal will be output if you input a
new trigger pulse before the video signal output for the
previous trigger pulse is output completely.
To Set the External Trigger Shutter
There are two ways to set the shutter speed.

To Use High-rate Scan Mode (B)
In external trigger shutter mode 1, you can increase the
rate by setting the shutter speed to the trigger pulse
width, and setting the high-rate scan mode switch on
the rear panel, the trigger interval, the external VD
phase and the external VD width.
The image is centered as shown below.
Notes
•In trigger shutter mode, video out signals are output
about 1 H later than the external VD.
•In high-rate scan mode, image output and WEN
rising edge are always synchronized, but WEN width
becomes undefined. High-rate scan mode cannot be
used in external trigger shutter mode 2.

•The shaded parts of the tables are items that you set or input yourself.
•The table is an example in external trigger shutter mode 1 where the

external VD falling edge is about 1 H (31.78 µs). In this case, about 3
lines at the end of the effective image segment are affected by trigger
input.
•The number of effective lines with high-rate scan set to ON is determined
by the formula shown below.

◆ HD/VD input
• Continuous VD input
*1 This is an external input signal. Make sure to input
both HD and VD signals.
*2 Exposure time (Te)
Te = Trigger pulse width + 6
µ sec
(The effective trigger pulse width for the external
trigger shutter operation is between 2
µ s and 1/4 s.)
*3 Normal operation is resumed when the trigger
pulse width is 1/3 s or more. The trigger falling
edge restores external trigger shutter operation. At
this time, the 50 ms after the falling edge of the
trigger pulse is an external trigger input inhibition
area. There is no guarantee of operation for any
trigger input in this period.
*4 If there is a falling edge on the external VD within
a period of +10
µ s from the falling trigger edge (1
and 2in the figure), it is not defined whether the
image is output for the external VD falling edge or
the image is output for the next external VD falling
edge. (1in the figure shows that the image is
output for the next external VD. 2shows the
image for the external VD.) In this case, see WEN
since output of the image and WEN make up a
pair. In any other case, the image is output for the
external VD falling edge after the trigger falling
edge (3in the figure).
Note
An image is not output correctly when the next trigger is
input before the image for the previous trigger has been
output.
