1 Introduction

The DCSG is a compact, low-power digital camera with an IEEE 1394

digital interface. It consists of a 640x480l, progressive scan CMOS imager

and associated IEEE 1394 electronics, mounted in a rigid, milled aluminum

alloy frame.

The CMOS imagers are MT9V032 sensors from Micron Semiconductor..

They are 1/3” format, with a resolution of 640 H by 480 V pixels, and come

in either monochrome (DCSG) or colorized (DCSG-C) versions. They

feature a global shutter, which means that all pixels are exposed at the

same instant. These imagers have excellent dynamic range, sensitivity,

anti-blooming, and noise characteristics. They are fully controllable via the

1394 interface: the user can set exposure, gain, decimation, etc. They have

better noise, sensitivity, and crosstalk characteristics than the previous

sensors.

The DCSG/C uses standard C/CS-mount lenses for user-changeable optics.

Wide-angle to telephoto options are available, depending on the

application.

There are software drivers for the DCSG for MS Windows 2000/XP, and

for Linux 2.4 and 2.6 kernels. These drivers are included in a Software

Developer’s Kit, which is bundled with the devices. Using the libraries in

the kit, you can quickly integrate DCSG video acquisition into your own

applications, written in C or C++.

1.1 Characteristics

• Micron MT9V032 Sensor

640 x 480 maximum image size

High sensitivity, low noise

Low pixel cross-talk

Global shutter

• Fully synchronized – video stream is synchronized to the

IEEE 1394 bus clock. Any other DCSG on the bus will

capture images at exactly the same time.

• Monochrome or Bayer Color

• High frame rates – 60 Hz for 640x480

• Electronic zoom mode – center 640x480 subwindow

• Extensive control of video parameters

Automatic or manual control of exposure and gain

Automatic control of black level

Manual control of color balance

• 50 Hz mode – reduces indoor light interference in

countries with 50 Hz electrical line frequency

• IEEE 1394 interface to standard PC hardware – carries

power and commands to device, data to PC

• Standard C/CS mount lenses, interchangeable – focal

lengths from 3.5 mm to 50 mm

• Anodized aluminum alloy chassis, high rigidity
