The TMC-1000 asynchronous reset operates with internal
sync or external HD for phase locking. When VINIT pulse
is applied, it resets the camera’s scanning and purges the
CCD.
There are three modes to control the asynchronous reset
and shutter speed.
1. External VINIT with pulse width control. The pulse
width between two pulse edges controls the shutter speed
externally from 1/16,000 sec. to 4 sec.
2. Internal shutter speed with fast mode. The video sig-
nal has no delay from the reset timing. The shutter speed
range is 1/2,000 to 1/16,000 sec.
3. Internal shutter speed with slow mode. The speed
control is variable from 1/15 to 1/1,750 sec. The video sig-
nal starts with internal V reset timing related to shutter
speed.

The TMC-1000 employs a color filter array (CFA) called a
“Bayer CFA” which comprises a ratio of two green pixels to
one red or blue pixel. The color interpolation is implement-
ed by digital signal processing developed by PULNiX.

The TMC-1000 has a substrate drain shutter mechanism
which provides a superb picture at various speeds without
smearing. Progressive scanning permits 1016 lines (2
lines less than the imager) of full vertical
resolution per single shutter. The manual
shutter-speed control selects the elec-
tronic shutter rate of 1/15 to 1/16,000 sec.
The user can assign any shutter speed to
any of the preset shutter positions. The
factory default values are as follows:
Shutter Control Switch
The asynchronous shutter is activated by selecting async
reset and the shutter speed. The async reset pulse, VINIT,
must be applied to set up the shutter. With VINIT high
(5V), the CCD keeps discharging. With a negative going
pulse to VINIT, the camera resets and purges the charge
momentarily. Then it starts integrating for the period of
shutter control set either by internal shutter control or
external pulse width control. If “0” shutter is selected in
async mode, the camera resets asynchronously without
shutter function; this can be used for applications requiring
strobe lighting.
Integration
Integration
The CCD imager of the TMC-1000 can be exposed for
longer than 1 frame timing (1/15 sec.) This feature pro-
vides high sensitivity for low light applications. Integration
is achieved by controlling the #11 pin of the 12-pin con-
nector to Low (GND). Integration also can be achieved by
VINIT pulse width control of the async shutter up to four
seconds.
