Introduction
1-3 General Description
1.2 Introduction
The MC-1000WU-20A is one of a series of high-resolution video cameras that
employs TI’s mega-pixel CCD image sensors. The cameras are intended for
scientific and industrial imaging applications where image data processing is
required.
The MC-1000WU-20A camera employs the TI TC215 full-frame CCD image
sensor, which features 1,017,000 active photosites, resulting in a very-high-
resolution image. The TC215 sensor provides high sensitivity and good
spectral response as a result of the TI patented Virtual Phase technology.
The TC215 sensor measures 17.2 mm diagonally and features 12-
m
m square
pixels. The square pixels permit symmetrical image measurement in both the
X and Y axis. The photosite has a 100% fill factor and is responsive to wave-
lengths in the ultraviolet through the visible and into the near-infrared spectral
regions. The camera outputs composite analog video at a 20-mega-pixel per
second data rate. Two operating options can be selected - a normal operating
mode and a programmable shutter mode. In addition, the camera provides for
auto-iris control.
A mechanical shutter or strobe light is recommended for most
MC-1000WU-20A camera applications. The shutter operation is synchronized
to the camera by supplying an external shutter command signal. The shutter
may operate from a minimum integration time of 1/2500 second to 1/125
second or 10 frames/s maximum. Figure 1–1 shows the camera interface
options and mode selection.
