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-mm 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.
