TM-250 Miniature CCD Camera

Operation Manual

1 Introduction

1.1 Product Description

The TM-250 is an inexpensive, high-quality camera that meets a variety of application requirements.
Featuring an advanced Hyper-HAD

resolution camera offers many standard and optional features at a very af fordable price. A CCIR-format
model, the TM-260, is also available.

1.2 Features

•

•

•

•

1

interline transfer 1/2" CCD imager, this miniaturized high-

Variable electronic shutter and random CCD integration

The substrate drain-type shutter mechanism provides a superb picture at various speeds without
smearing. The electronic shutter rate can be externally adjusted, from 1/60 to 1/10,000 (1/29,100 in
some operating modes) in discrete steps, via a manually controlled DIP switch on the back panel.

Miniaturized and lightweight

The use of a CCD image sensor in the video camera module and the development of special mini
C-mount lenses allow the TM-250 to be compact, lightweight, robust, and small enough to operate
just like a remoted head.

High sensitivity

The TM-250 camera is one of the most low-light sensiti v e 1/2" CCD cameras a vailable today . This
feature is especially important when using the faster shutter speeds. The CCD detects images into
the near-infrared spectrum. It requires only 1.0 lux of minimum illumination and 0.5 lux minimum
illumination at maximum gain. In general, this allows the use of a higher lens F-value while
providing a greater field depth and sharper images.

Low lag/high resistance to image burning

1. Hyper-HAD is a trademark of SONY Corporation.

TM-250 Miniature CCD Camera

Page 2
Introduction

Because the CCD is highly resistant to image burning, the camera may be exposed to bright objects
for a long period of time. Because a “smear” phenomenon may occur when shooting a very bright
object, we recommend an infrared cutoff filter to obtain a clear picture (optional).

•

AGC/MGC selection, manual gain control and gamma adjustment

These adjustments, which are particularly important in vision system applications, are externally
adjustable via switches on the rear plate.

•

Genlock circuit

A genlock circuit is built in to accept external sync for applications in which external sync is
required.

•

High resistance to magnetic field and vibration/mechanical shock

The CCD imager’s rugged design allows it to withstand strong vibration and shock with little or no
noise appearing in the picture. Since the TM-250 is not influenced by a magnetic field, it will
produce stable images even when placed next to objects such as electric furnaces, welding
machines or NMR scanners.

Quick start-up and low power consumption

•

Image capture can begin within a second after turning on the camera. The power consumption is
only 2.5W. This makes the camera excellent for use with battery-operated systems.

Camera-mounting flexibility

•

The TM-250 has tapped holes on all four sides to allow a tripod mount to be installed from any
angle.

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.

1.4 Applications

The miniature size of the TM-250 camera eliminates the need for a remoted imager camera in all but the
most confined spaces. This camera fits easily , both physically and functionally, into all types of machine
vision, automated inspection, and related applications. Other uses include remotely piloted vehicles,
miniature inspection devices, surveillance, microscopes, and medical equipment.

balanced for 75Ω termination. Standard RG-59 type coaxial cable should carry a full video signal for up
to 500 feet.

To output the video and input the power and sync to a camera over a single cable, use the PULNiX
multi-conductor cables, such as the 12P-02S, etc. The mini coaxial leads in PULNiX multi-conductor
cables are designed for short runs of no longer than 100 feet.

Note: Make sure that no extraneous wires are visible which could cause a short.

2.2.4 Attaching the Camera Lens

The TM-250 camera accepts 1/2" or larger format size C-mount lenses. To attach the C-mount lens to
the camera, carefully engage the threads and rotate the lens clockwise until it firmly seats on the
mounting ring. Do not force the lens if it does not seat properly. Please note that some lenses with
extremely long flangebacks may exceed the mounting depth of the camera.

2.2.5 Auto-Iris Lens Setup

Auto-iris lenses with full video input can be used with the PULNiX TM-250, although this camera
model does not come equipped with auto-iris output.

Note: Make sure that the power is r emo ved from the camera before connecting or disconnecting

the auto-iris lens. There is a small chance that the auto-iris lens could be damaged by
plugging or unplugging it while the camera is powered up.

Power down the camera before installing the auto-iris lens. To install the auto-iris lens in a PULNiX
camera without an auto-iris output, wire the signal (video) on the lens into the terminal 1 Vp-p video
output on the camera.

Point the camera at a light area and then quickly towards a darker area. If everything is working
properly, the iris should adjust for the light change.

2.2.6 Monitor Display Mode

For monitoring real-time video, connect the video output to a video monitor or other device.

3.1.3 Field and Frame Modes

The standard factory setting for the TM-250 camera is FRAME MODE. The field and frame integration
mode is selectable using the switch on the rear panel of the camera. The frame integration is used to
separate all CCD pixels. The exposure of Odd and Even fields generates the full frame image shown in
the figure below.

3.1.3 (a) Field Mode

In Field mode, two horizontal rows are scanned (binned) simultaneously. At each interlace scan, the
scanned pairs are changed. Thus the sensitivity of the CCD is doubled for one field of integration. When
compared to Frame mode, in which each horizontal row is scanned simultaneously , the CCD obtains the
same sensitivity in half the time period. This mode is useful when Shutter is used. The field integration
is done by combining two pixel rows (binning) together and each pair alternates as interlace scan is
generated. Row 1 is binned with row 2, and ro w 3 is binned with row 4. In Field 2, row 2 is binned with
row 3, row 4 with row 5, and so on. The field mode is very effective in shutter mode since the pixel
sensitivity is doubled for field integration (1/60 sec) and equals with frame mode (one row at 1/30 sec).
Since shutter mode is only one field output per shutter and darker than normal image, two-row binning
is effective. This mode also reduces interlace moire when a sharp horizontal pattern is observed. For
higher pixel definition such as gauging and sub-pixel interpolation, Frame mode operation is
recommended.

Moire is unnoticeable because of alternating two-row scanning. The v ertical resolution in Field mode is
not as good as that in Frame mode, but it is sufficient to view the full vertical resolution of the TV
format.

3.1.3 (b) Frame Mode

In Frame mode, each horizontal row is scanned as interlace scanning. The integration of each pixel is
one frame period. In Frame mode, vertical pixel resolution is good, and the exact location is obtained. In
comparison with Field mode, however, Frame mode has the disadvantage of showing vertical Moire.
Frame mode should be used in applications that need strobe lighting, because full frame resolution is
achieved in this mode. For higher pixel definition such as gauging and sub-pixel interpolation, Frame
mode operation is recommended.

3.2 External Sync

The TM-250 can accept external sync from an external sync generator or frame grabber. Its input
specifications are:

Internal/External auto switch
fH=15.734 KHz ±5%, fV=59.95 Hz ±5%

Note: The TM-250 has a one (1) horizontal line delay between the input VD signal and the

output video. If external vertical drive (VD) is applied to the camera, it may cause the
video output to be delayed 1 HD (1 HD = ~64.0 µs). If the imaging system is capable of
automatically detecting the start of video (within a few HD), then no problem will exist. If
it is not capable of automatically detecting the start of video, you may need to reconfigure
the video capturing sequence to delay video acquisition of 1HD.

3.2.2 Interfacing to Frame Grabbers

The TM-250 camera can be connected to a frame grabber using either the 12-pin connector or the BNC
connector on the rear panel of the camera.

3.3 Operating Modes

Besides normal operation, the TM-250 supports the following versatile operations that can be selected
by the DIP switch on the rear panel of the camera:

• Standard Interlace Mode

Field integration Mode
Frame Integration Mode

• External Sync Mode

• Non-interlace Mode

• Cyclic (Continuous) Shutter Mode

• Asynchronous Reset and Asynchronous Shutter

3.3.1 Standard Interlace Mode

3.3.1 (a) Field Mode and Frame Mode

The field and frame integration mode is selectable. The frame integration is used to separate all CCD
pixels and the exposure of Odd and Even fields generate the full frame image sho wn in the figure belo w.

3.3.1 (b) Field Mode Binning

The field integration is done by combining two pixel rows (binning) together, each pair alternating as
interlace scan is generated. Row 1 is binned with row 2, and ro w 3 is binned with row 4. In Field 2, row
2 is binned with row 3, row 4 with row 5, and so on. Field mode is very effective in shutter mode
because the pixel sensitivity is doubled for field integration (1/60 sec) and equals frame mode (one row
at 1/30 sec). Because Shutter mode is only one field output per shutter and darker than normal image,
two-row binning is effective. This mode also reduces interlace moire when a sharp horizontal pattern is
observed. For higher pixel definition such as gauging and sub-pixel interpolation, Frame mode
operation is recommended.

3.3.2 Cyclic (Continuous) Shutter Mode

With back-plate shutter control, the TM-250 operates at the internally predefined shutter speeds. Each
field output is exposed for the same period. The shutter control varies the substrate discharge timing.
The duration between the shutter pulse and transfer gate timing (11H from VD edge) decides the
exposure time (16H for CCIR). The following three cyclic shutter modes are available:

• High-Speed Cyclic Shutter mode

• Trigger Position Reset/Restart Shutter mode

• Trigger Width Reset/Restart Shutter mode

Contact PULNiX for timing charts of various cyclic shutter modes.

3.3.3 Asynchronous Reset and Asynchronous Shutter

By supplying VINIT pulse on pin #6, the camera can be reset asynchronously. In this mode, when
VINIT is kept high, it continuously discharges the CCD and outputs the field video signal upon the
negative going edge. The output stays continuous during VINIT low. The first field output is always
Odd.

TM-250 Miniature CCD Camera

Page 15

Operation

The following four asynchronous shutter modes are available:

• Strobe Asynchronous Shutter Mode

• Pre-Reset Asynchronous Shutter Mode

• Post-Reset Asynchronous Shutter Mode

• Pulse Width Asynchronous Shutter Mode

Please contact PULNiX for timing charts of various asynchronous shutter modes.

3.3.4 External Sync Mode

TM-250 accepts standard RS-170 external sync, which is defined as horizontal sync (HD) and vertical
sync (VD). The phase-locked loop jitter is designed to be the minimum (< 5ns) in this category using
the latest PLL chip. The wide capture range enables the camera to operate at an extended temperature
range (optional) of -35°C to 65°C. HD and VD input is TTL level and the high impedance is 100KΩ or
75Ω (optional).

3.3.5 Reset-Restart Mode

Rather than using VINIT as asynchronous reset, the camera can be reset using EXT VD. In this mode,
the camera needs multiple VD pulses to output valid images, depending on whether it is set to Field or
Frame mode. Usually, the first field (Field mode) or the first frame (Frame mode) are garbage because
of previous signal residuals prior to reset. A frame grabber has to know which frame or field to capture.
External HD must be applied for this operation.

3.3.6 External Shutter Control

The shutter speed or exposure can be controlled with external pulse (TRIG) in this mode. In
combination with Reset-Restart Pulse (EXT VD), the camera can be externally controlled for image­capture timing as well as for exposure time.

This is an excellent application for capturing multiple images (two fields of images) of indexing objects
under various lighting or brightness conditions. When Frame mode is selected, the full vertical
resolution is achieved by taking two fields of shutter images, whether or not you are using an electronic
shutter.

3.3.7 Integration

When integration control (VINIT) is low, the CCD imager keeps integrating. When the signal returns to
high, it enables the charge transfer for video output. This mode integrates longer than one field. With
strobe light application, it can capture randomly strobed images during the integration. It also increases
the exposure time to enhance low-light viewing.

3.3.8 Non-Interlace Operation

With non-interlace external sync, the camera operates at non-interlace scanning. External VD must be
generated at integer of 262H ± 8H. (Standard interlace is 262.5 H)

TM-250 Miniature CCD Camera

Page 16
TM-250 External Signals

4 TM-250 External Signals

This section explains how the external signals (VD and HD) and shutter trigger signal (VINIT or TRIG)
must be fed in Async Mode operation, Integration Mode operation, and Reset-Restart operation.

4.1 External VD

The TM-250 I/F circuit intentionally delays the external VD for two pixel clock period. This ensures
that the phase of external HD comes earlier than that of VD with an y cable length and absorbs the effect
of jitter caused by the user's sync generators. Assuming that the device propagation delay is more than
zero nanoseconds and the external VD timing is created by the edge of external HD, the HD must come
earlier than VD. Some sync generators, however, produce both VD and HD exactly in phase. In this
case, external factors like jitter or parasitic cable effects may cause VD to come earlier than HD as
shown in Figure 5 below.

FIGURE 5. External VD

EXT HD

EXT VD (R.R.)

Two-pixel delay

Internal VD

4.2 External HD and Internal Sampling Clock

To ensure stable operation without influence of jitter, the TM-250 latches Shutter Trigger Pulse (TRIG)
using internal sampling clock called HCLK (half line clock). The frequency of HCLK is double of the
external HD and two pixels earlier than external HD in terms of timing. Figure 6 below shows that the
TRIG is latched in 1/2 line later for this reason.

FIGURE 6. Proper Operation

EXT HD

Two pixels earlier

HCLK

TRIG

Sample SampleSample

TM-250 Miniature CCD Camera

TRIG detected

4.3 Width Mode Reset-Restart Operation

In Width Mode Reset-Restart operation, the leading edge and trailing edge of TRIG must both be
synchronized with external HD. In addition, the duration must be 1 line or longer in one-line step. If the
TRIG does not meet these conditions, the exposure time may vary from the position and the field.

Figure 7 below illustrates the proper operation with constant 2-line exposure period. Figure 8, on the
other hand, illustrates the illegal operation where the exposure time varies by the position of TRIG.
Shutter Trigger generates 1-line long-exposure at position A and 2-line-long exposure at position B
because the TRIG pulse is clocked in the same timing but the termination does not have the same
timing. The same happens by the difference of field (odd or even).

Time

In this cyclic operation, the camera generates its own synchronization signal and cyclically transfers the
photo-charge. Since no discharge occurs, the one full frame time (60mS) is the exposure time for both
fields in Frame Accumulation mode, as sho wn in Figure 9 below, and one full field time (30mS) in Field
mode as shown in Figure 10 on page 19. The discharge pulse dumps photo-electrons accumulated in the
photoreceptor which mechanism is called electronic shutter. Since the discharge pulse is not employed
in this mode, we refer this mode to “NO” shutter.

5.1.2 Fast Shutter Cyclic Mode

In this shutter mode, the camera generates its own synchronization signal and cyclically carries out the
internal shutter operation. The discharge and transfer repeats in every field at a predefined timing. The
discharge occurs in every line and stops at the defined timing in one field. The duration between the last
discharge and transfer determines exposure time.

5.1.3 Trigger Position Reset/Restart Shutter Mode

The shutter trigger pulse (TRIG) needs to synchronize with Reset-Restart (EXT VD) pulse. It should be
2 lines or more in width. The leading edge of TRIG pulse produces DSUB (discharge) pulse and starts
the exposure. The transfer (read-out) occurs at the 11th line after EXT VD pulse is fed. A full picture
field can be obtained in every field. The TRIG must be wider than one line.

5.1.4 Trigger Width Reset/Restart Mode

The timing of the trigger pulse is not critical. It is, rather, the duration (width) that is important for
precise exposure time. The shutter pulse does not need to synchronize with Reset-Restart (EXT VD),
and can synchronize with moving objects.

A full picture field can be obtained on every other field, rather than on consecutive fields, as shown in
Figure 13, “Trigger Width Reset/Restart Shutter Mode Timing,” on page 22, because V shift has to be
stopped after the transfer pulse, and resume after the 11th line. Because V shift has been halted, part of
the field cannot be shifted out. To get a full picture field, the next shutter trigger must be prohibited,
which means a full picture is possible only on every other field. If a full picture field is required one
after another, the falling edge of the shutter pulse must fall between the 1st line and the 11th line to
ensure shift out of all the transferred charge from the previous transfer in FIELD accumulation mode.
This operation is similar to that of Trigger Position shutter, except that the timing is less critical.

5.2.1 TM-250 Strobe Asynchronous Shutter Mode

This asynchronous mode is intended for use in strobe applications. In this mode, the horizontal timing
can be synchronized with external HD. The camera operates in the same way as in Pre-reset mode async
operation. But the leading edge of VINIT simply resets the camera and the discharge does not occur in
this mode so that the strobe must engage after VINIT pulse implied but before transfer occurs at 11th
line for TM-250, and at 16th line for TM-260. When the F2 switch is Up (ON) in Frame storage mode,
the camera obtains both odd and even field pictures.

5.2.2 Post-Reset Asynchronous Shutter Mode

The operation of this shutter is similar to Cyclic Fast mode. But the exposure starts in sync with an
external pulse called VINIT pulse. On the leading edge of VINIT, single discharge pulse occurs and all
the photo-charge is damped. Different from Pre-reset Mode, the internal counter reset takes place when
predefined exposure time has passed after the discharge. The photo transfer occurs at the first line of the
odd field right after the reset. Vertical shift starts after 11H for TM-250, and after 16H for TM-260.
Only the image in the first odd field is valid. SYNC signal is continuous when F2 switch is Up (ON).
SYNC is available only in the one field right after VINIT when F2 is down (OFF).

Pulse W idth Mode Async Shutter enables exposure time to be controlled by the duration of VINIT. The
camera operates in the same way as it does Fast Mode Async Shutter or Pulse Width Mode Integration.
Unlike Pulse W idth Mode Integration, the single pulse of dischar ge occurs only when the falling edge of
VINIT pulse is detected. The rising edge of VINIT resets camera, and photo-charge is transferred
simultaneously at the 1st line so only odd field image is valid. SYNC signal is continuous when F2

5.2.4 Pre-Reset Asynchronous Shutter Mode

The purpose of this mode of operation is to maintain compatibility with the TM-7/6 and the TM-200/
300 series cameras. This shutter operation enables image capture at extremely high speeds with very
short exposure times and image output with a minimum of delay . In contrast with Post-Reset Mode, the
falling edge of the VINIT pulse first resets internal counter logic to the beginning of the odd field. The
discharge of photo-charge occurs at a predefined period later after the reset, then the transfer pulse
occurs at the 11th line for the TM-250, and the 16th line for the TM-260. For this reason, the exposure

time can be less than 11 lines for the TM-250 and 16 lines for the TM-260. If the F2 switch is Up (ON),
VSYNC is continuously generated and the camera behaves the same as in High-speed Cyclic shutter
operation. When F2 is OFF, VSYNC appears in only the field right after VINIT when F2 is down (OFF).

5.2.5 Double Pulse Integration Mode

Double Pulse Integration mode enables exposure times to be longer than one field. It also works for
strobe applications. The camera operates in the same way as it does in Asynchronous Strobe Shutter
mode. The transfer occurs only at one field in Field Accumulation mode, or at two fields in Frame
Accumulation mode after the leading edge of VINIT pulse is detected. Dischar ge does not occur in this
mode so that the previous VINIT clears the photo accumulation, as in Cyclic No Shutter. Sync signal is
continuous when F2 switch is up (ON). Sync is available in the two fields (frame mode) and in the one
field (field mode) right after VINIT when the F2 switch is down (OFF).

5.2.6 Pulse Width Integration Mode

Pulse width mode integration enables exposure time to be longer than one field and also works for
strobe application. The camera operates in the same way as it does in Async Pulse W idth Mode Shutter.
When VINIT is high, train of dischar ge pulse occurs. When the f alling edge of VINIT pulse is detected,
the discharge stops and photo-charge accumulation starts. The rising edge of VINIT reset camera and
transfer happens at 11th line with TM-250 and at 16th line with TM-260. The transfer occurs only at
one field in field accumulation mode or at two fields in frame accumulation mode. SYNC signal is
continuous when F2 switch is Up (ON). SYNC is available only in the two fields (frame mode) and in
the one field (field mode) right after VINIT, when the F2 switch is down (OFF).

Flange Surface of
C-Mount

The flange-back length of the CS-Mount is 12.5mm versus 17.526 of the C-Mount. The shorter flange­back length of the CS-Mount allows room for the stripe filter incorporated in the color camera.
Additionally, the shorter flange-back length allows for reduction of the effective diameter of the first
lens and reduces the number of lens elements. The common C-Mount lens is completely compatible
with a CS-Mount camera when a 5mm extension ring is inserted between the lens and the camera.
