Relative Sensitivity
The TM-250/260 camera offers a high-resolution interline
transfer 1/2" CCD imager in a very tiny package.The camera’s
extremely short length allows it to fit into very shallow
spaces, even when using normal-size connectors. In contrast,
most other cameras leave very little extra space when used
with specific C-mount optics and standard connectors.
The TM-250/260 front end measures 44mm square, and the
imager center is located at the same distance from either side.
This means that the
camera can be
49.6 [1.95}
mounted either right
side up or sideways
without changing the
TM-250
optical axis. All circuit
boards are securely
93.4 [3.68]
integrated inside the
64.9 [2.56]
camera to assure the
most robust design
for the most
TM-200 and TM-7
demanding applications.
The camera is avail108.7 [4.28]
able in two formats:
108.8 [4.28]
EIA (TM-250) and
CCIR (TM-260). It

has many standard
COMPETITORS
and optional features
65.0 [2.56]
at a very affordable
price. In a departure
from the common practice of using a standard CCD and its
chipset, the TM-250/260 uses a PULNiX-proprietary timing
generator chip.This allows the TM-250/260 camera to be used
as a base model for OEM applications that require highly specialized, custom cameras with non-standard options.
The most commonly needed adjustments–manual gain control, automatic gain control, gamma, and field/frame
selection–can be easily accessed on the camera’s rear panel.
Electronic shuttering is another standard feature with continuous or async, reset-restart modes. Fourteen shutter
speeds, ranging from 1/60 sec. to 1/29,000 sec., can be selected
externally using the switch on the rear panel.
These cameras fit 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.

❶ Standard Interlace Mode
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 shown in
the figure below.

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 row 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.

❷ External Sync Mode
The TM-250/260 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).
❸ Non-Interlace Operation Mode
With external sync of non-interlace, the camera operates at
non-interlace scanning. External VD must be generated at integers of 262H ± 8H. (Standard interlace is 262.5 H)
❹ Cyclic (Continuous) Shutter Mode
With back-plate shutter control, the TM-250/260 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.

Operating Modes (Continued)
➎ Asynchronous Reset and Asynchronous
➐ Reset-Restart with Electronic Shutter
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.
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
The shutter speed or exposure can be controlled with external pulse width control or external pulse position control in
this mode. In combination with Reset-Restart pulse (EXT.VD),
the camera can be externally controlled for the image-capture
timing as well as the 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 even using an electronic shutter
by taking two fields of shutter images.
EXT. HD for PLL(Relationship with HD and Reset-Restart VD affects Odd or Even field output)
Please contact PULNiX for timing charts of various asynchronous shutter modes.

➏ Reset-Restart Mode
Rather than using VINIT as async 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 first frame (frame mode) is 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.

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