FEATURES
AND
APPLICATIONS
HIGH
RESOLUTION,
INTERLINE
TRANSFER
CCD
The
TM-745E/TM-765E
is
a
state-of-the-art
CCD
camera
which
uses
a
2/3
inch
high
resolution
imager.
This
unit
offers
outstanding
compactness,
high
performance,
long
Ше,
high
stability
as
well
as
a
number
of
technical
innovations
such
as
variable
electronic
shutter
and
random
ССО
integration.
Its
diversified
features
allow
for
versatile
applications
such
as
machine
vision
and
image
processing,
robotics,
medical,
and
surveillance
applications.
VARIABLE
ELECTRONIC
SHUTTER
AND
RANDOM
CCD
INTEGRATION
The
TM-745E/TM-765E
has
a
substrate
drain-type
shutter
mechanism
which
provides
a
superb
picture
at
various
speeds
without
smearing.
The
camera
has
the
capability
to
externally
vary
the
electronic
shutter
rate
via
a
manually
controlled
BCD
switch
from
1/60
to
1/10,000
sec.
in
discrete
steps
(1/31,000
sec.
optional).
Random
field
CCD
integration
is
available
.
Full
frame
integration
is
possible
through
special
modifications.
MINIATURIZED AND LIGHTWEIGHT
Ali
PULNiX
cameras
are
built
with
the
same
design
principles,
that
is:
solid
state
technology;
miniaturization
(including
lenses,
housings,
and
cables);
specialization
(such
as
remote
imager
and
image
intensified
camera
versions).
The
use
of
a
CCD
image
sensor
in
the
video
camera
module
and
the
development
of
special
mini
C-
mount
lenses
makes
it
possible
to
produce
a
very
compact,
lightweight,
and
robust
series
of
cameras.
LONG
LIFE:
A
THREE
YEAR
WARRANTY
The
CCD
solid
state
image
sensor
allows
the
camera
to
maintain
a
superior
performance
level
indefinitely
while
requiring
virtually
no
maintenance.
PULNIX
backs
all
of
the
TM
series
cameras
with
a
three
year
warranty.
WARNING:
Unscrewing
the
camera
cover
or
opening
the
camera
in
any
way
will
void
this
warranty.
PRECISE IMAGE GEOMETRY
On
the
CCD
image
sensor,
the
photosensor
elements
form
exact
rows
both
horizontally
and
vertically
so
that
a
very
precise
image
geometry
may
be
obtained.
Moreover,
the
TM-765E
image
sensor
features
uniform
square
pixels
(11
x
11
microns)
making
it
an
obvious
choice
for
use
with
computer
image
processing
systems
or
for
precise
pattern
measurements
and
gauging.
LOW
LAG
AND
HIGH
RESISTANCE
TO
IMAGE
BURNING
Compared
to
the
lag
of
conventional
cameras
which
use
a
pickup
tube,
the
lag
of
a
CCD
camera
is
considerably
reduced
so
that
a
clear
picture
may
be
obtained
when
shooting
a
rapid
moving
object,
or
when
shooting
in
a
low
illumination
environment.
Since
the
CCD
is
highly
resistant
to
image
burning,
the
camera
may
be
exposed
to
bright
objects
for
a
long
period
of
time.
It
must
be
noted
that
a
“smear”
phenomenon
may
occur
when
shooting
а
very
bright
object.
An
infrared
cutoff
filter
is
recommended
to
obtain
a
clear
picture.
HIGH SENSITIVITY
The
TM-745E/TM-765E
is
one
of
the
most
low
light
sensitive
CCD
cameras
available
today.
This
is
especially
important
when
using
the
faster
shutter
speeds.
The
CCD
detects
images
into
the
near
infrared.
It
requires
only
0.5
lux
of
minimum
illumination
and
0.2
lux
minimum
illumination
at
maximum
gain.
In
general,
such
a
low
light
camera
allows
use
of
a
higher
lens
F-value
and
provides
greater
depth
of
field
and
sharper
images.
HIGH
RESISTANCE
TO
MAGNETIC
FIELD
AND
VIBRATION/MECHANICAL
SHOCK
Due
to
its
ruggedized
design,
the
CCD
imager
can
withstand
strong
vibration
and
shock,
and
little
or
no
noise
will
appear
in
the
picture.
Since
the
TM-745E/TM-765E
camera
is
not
influenced
by
a
magnetic
field,
it
will
produce
stable
images
even
when
placed
next
to
objects
such
as
electric
turnaces,
welding
machines,
or
NMR
scanners.
QUICK
START-UP
AND
LOW
POWER
CONSUMPTION
No
more
than
a
half
second
is
needed
for
the
TM-745E/TM-765E
to
warm
up,
and
shooting
may
begin
within
a
second
after
turning
on
the
camera.
The
power
consumption
is
only
4.0W.
This
makes
the
cameras
excellent
for
use
with
battery
operated
systems.

GENLOCK CIRCUIT
А genlock circuit is built into the TM-745E/TM-765E to accept external sync for industrial applications as well as
for surveillance locking. This flexible genlock will take either interlace or non-interlace H and V sync.
AGC SELECTION, MANUAL GAIN CONTROL AND GAMMA ADJUSTMENT
The AGC (automatic gain control) may be switched internally from automatic to fixed gain. Gamma may be set
either to 1 or to maximum compensation 0.45. These adjustments are particularly important in vision system
applications.

ЗЕСТЮН 4 CAMERA SYSTEM ACCESSORIES
The TM-745E/TM-765E consists of the camera body and the lens mount. Additionally, PULNIX offers the
following accessories:
4.1 SHUTTER CONTROL UNIT (SC-745) consists of a manually controlled 8-position BCD switch that
determines the exposure time of the sensor. It connects to the TM-745E/TM-765E via a cable with a PC-6P male
connector that plugs into the 6-pin female connector socket on the back of the camera. The SC-745 for shutter
control is included with camera.
4.2 POWER CABLES - all power cables use a PC-12P female connector that fits into the 12-pin male
connector on the back of the camera. Due to the connector's miniature size, PULNiX recommends purchasing
the following pre-assembled cables: KC-10 10 feet, 4 conductor cable (12V, GND, Hd, Vd); 12POX variable
length, 8 conductor cable (12V, GND, Но, Мо, video, Async reset, integration control)
Note: Consult PULNIX for custom cable assemblies.
4.3 LENSES - PULNIX offers a wide variety of 2/3 inch format mini lenses. Auto-iris lenses must have a cable
equipped with a PC-6P connector mating into the 6-pin female connector on the back of the camera.
Note: Normally, the TM-745E/TM-765E cannot do variable shuttering while using an auto-iris lens because these
functions share one 6-pin socket. The user has to build his own interface in order to use both an auto-iris lens
and a shutter control switch. This is done by separating the +12VDC, GND and video wires (for the auto-iris
lens), and the Do, D1, and D2 controls (for the BCD switch).
4.4 POWER SUPPLIES - PULNiX recommends the following supplies:
K25-12 110V AC/12V DC, 2.1A regulated supply
P-15-12 220V AC/12V DC, 2.1A regulated supply
K50-12 110V AC/12V DC, 4.2A regulated supply
PD-12P 110V AC/12V DC, 0.5A regulated supply
SECTION 5 SETUP AND OPERATION
The operation of the TM-745E/TM-765E requires a lens (mini or standard C-mount), a 12V DC regulated power
supply, power and video cable assemblies and, if needed, a shutter control unit. Setup of the camera system is
as follows:
5.1 LENS MOUNT
The TM-745E and TM-765E cameras have a permanent C-mount attached to the imager portion of the camera.
Lenses are mounted by carefully threading the lens into the mount in a clockwise direction. Turn the fens until
completely seated on the mount. Most all standard C-mount lenses should fit the TM-745E/TM-765E. However,
some specialized lenses may have an extremely long flange back which exceeds the mounting depth of the
camera. Do not force a lens which does not appear to fully seat. Lens extention tubes such as the CR-5, CR-10,
and CR-20 are used by attaching first to the lens and then mounting the entire assembly to the camera. CS style
lenses, though they share the common C-mount thread, are not compatible with the standard TM-745E/TM-765E
mount
due
to
a
different
rear
focus
specification
for
the
CS
format.

5.2 AUTO-IRIS LENSES
Auto-iris lenses require a 6-pin male connector (РС-6Р) mating into the female connector on the back of the
camera. Connect +12V DC, GND and Video to each pin as indicated in the following.
N Connector

5.3 SHUTTER CONTROL UNIT (SC-745)
The TM-745E/TM-765E uses a manually controlled 8-position BCD switch, SC-745, to set the shutter speed of
operation. The switch is connected to the camera via a cable that has a PC-6P male connector attached to it
which plugs into the above illustrated 6-pin camera socket.
5.4 POWER CABLES AND POWER SUPPLIES
The TM-745E/TM-765E uses a PC-12P mating 12-pin power connector. If using any of the PULNIX connector
and cable assemblies, please note that the yellow lead is +12V DC and gray is GND. Connect the yellow lead to
the +12V of the power supply and attach the gray lead to the power supply’s ground. Make sure all other leads
are not touching as this will cause the camera to malfunction. When powering the camera, use only a regulated
12VDC
power
supply.
The
TM-745E/TM-765E
has
a
narrow
voltage
intake
range
(11V
to
14V
max).
If
unregulated voltage or voltage lower than 11V is applied, noise will appear on the monitor.

5.5 VIDEO OUTPUT
The
video
output
impedance
of
the
camera
is
7502
and
requires
a
coaxial
cable
with
matching
impedance.
The
end of
the video
cable
or
the
monitor
must
be terminated
а! 750 as
well.
Standard
video
cable with
proper video
connectors
may
be
obtained
at
most electronics
hardware
stores.
Connect
one
end of the video
cable
into the
standard
video
connector
located
on
the
back
of
the
camera and
insert
the
other
end of the cable
into
the CCTV
monitor.
Alternatively,
video
output
is
also
transmitted
via pin 4
of the
camera’s
12
pin
connector.
5.6 EXTERNAL SYNC
The TM-745E/TM-765E does not require external sync in order to run directly into a CCTV monitor. However,
some applications (such as multiple camera switching and some vision systems) will require that the camera be
externally synced. The unit has a built-in genlock circuit which will accept an external Hp and Ур sync signal; the
built-in phase lock loop (PLL) adjusts its internal frequency to lock the camera to the external sync by allowing the
internal crystal oscillator to automatically switch to a voltage controlled oscillator. Pins 7 and 9 of the TM-
745E/TM-765E's 12-pin connector accept external Ур and Hp.

frame resolution is obtained. (Note: Full frame is not available in the shutter mode).
1. Select frame mode on driver PCB (Factory standard). If the setting is in the field mode in order to enhance
shutter sensitivity, move solder jumper to frame side.
2. Apply the integration control to low (GND) to pin #11 of 12-pin connector. This allows the TM-745E/TM-765E
to operate with integration.
3. Арру ext. sync (Hp, Мо); Hp - continuous, Мр - continuous or integration control interval pulse.

3. Transmission of charge
When a high voltage is applied to the electrodes, a deeper well
is
formed;
when
a
low
voltage
is
applied,
a
shallower
well
is
formed.
Inthe
CCD,
this
property
is
used
to
transmit
the
charge.
When
a
high
voltage
is
applied
to
the
electrodes,
a
deep
electric
potential
well
is
formed,
and
charge
flows
in
from
neighboring well. When this is repeated over and over among
the
regularly
arranged
electrodes,
the
charge
is
transferred
from
one
MOS
capacitor
to
another.
This
is
the
principle
of
CCD charge transmission.

8.2 MECHANISM OF ССО CHARGE TRANSFER
1.
Vertical
transfer
2
The
vertical
shift
register
transfers
charges
using
а
four-phase
=
drive
mode.
Figure
1
shows
an
example
of
the
changes
which
can occur in potential wells in successive time intervals. At
tO, the electrode voltages are (V1 = V2)>(V3 = V4), so the
potential wells are deeper toward the electrode at the higher
voltages V1 and V2. Charges accumulate in these deep
wells. Atti, the electrode voltages are (V1 = V2 = V3)>(V4),
so the charges accumulate in the wells toward the electrode at
V1, V2 and V3. At 12, the electrode voltages are (V2 =
V3)>(V4 = V1), so the charges accumulate in the wells toward |
the
electrode
at
V2
and
МЗ.

t8(V1 = V2)>(V3 = V4) (Initial state)
These
operations
are
repeated
to
execute
the
vertical
transfer.

2. Horizontal transfer
The horizontal shift register transfers charges using a two-
phase drive mode. Figure 2 shows an example of the
changes which can occur in the potential wells in successive
time intervals. Atti, the electrode voltages are H1>H2, so the
potential wells are deeper toward the electrode of the higher
voltage H1. The charges accumulate in these wells. At t2, Output section

H2

At
t3,

the electrode voltage has not changed since t2, so the charge
flows into the wells at H2 and one transfer of charge is
completed. These operations are repeated to execute the
horizontal transfer.

9.2 SPECIAL FUNCTIONS:
9.2.1 SHUTTER The TM-745E/765E has a built in shutter control up to 1/10,000 sec. As an option, 1/31,500
sec. shutter speed is available. When this option is selected, Vp phase adjustment option is not available. VD
phase adjustment is used to align video vertical timing to external sync leading edge. Standard without
adjustment is 3.5H (fixed).
Phase adjusted au
Ext. Vd The shutter timing is synchronized with the CCD transfer
gate timing of each field. Because of the shutter principle,
= oniv опе field image per shutter is output. If one frame of
Int. Vd
à | | shutter image is captured, two separate images will be
displayed due to object motion.
9.2.2 INTEGRATION Integration is a longer exposure than
the standard 1/30 sec. of frame speed. The TM-745E/765E
provides a full frame of integration image. Pin 11 of the 12-
ki pin connector is used to control integration. The standard
model is normally pulled up (5V), and when Pin 11 is Low
(GND), the TM-745E/765E maintains the integration until Pin 11 goes to high.
‘SHUTTER INTEGRATION
The integration image is quite different from TM-840N(frame transfer CCD). TM-745E/765E signal processing
keeps optical black level as reference black video to clamp the video level, and thermal noise during integration is
cancelled off. Non-optical black clamping is also available as an option. Please consult PULNIX for special
integration applications.
