Table A-18 lists the technical specifications for the O2Cam.
Table A-18 O2Cam Technical Specifications
Sensor 512 x 480 NTSC Color CCD, 1/3 in. format.
Standard lens F2.0, 6mm with M11 screw mount and built-in IR filter.
Output format Outputs 640 x 480 square pixel NTSC frames @ 29.97 Hz (780 x 525 total
frame), as 422YCrCb pixels with 1 byte luminance followed by 1 byte
chrominance, on a 24.5 MHz interface clock.
Automatic Gain Automatic Gain Control adjusts gain to achieve average output
Control brightness. AGC can be activated or overridden (via new gain value) from
workstation.
Shutter speeds Selectable from 1/60 through 1/10,000 second.
Auto white balance Software initializes camera at workstation power on and loads red and
blue balance, red and blue saturation, and gamma values that are
balanced for offices with or without windows, with incandescent and/or
fluorescent lights. User can make additional white balance adjustments
with the digital media software.
Gamma correction Gamma factor of 0 or 255 can be loaded into camera by workstation at any
time.
Push button The control button drives the GPIBIN line on the 68-pin connector. While
button is up, voltage is high; while button is down, voltage is low.
Power requirements 1W @ 5V (200mA), 1W @ 12V (80mA), and 12 mW @ -12V (1mA) are
provided by the workstation. These are maximum amounts available to
the camera. Actual consumption should be lower.
LED indicator On/off state is controlled by the workstation via I
Workstation interface DVCI uses 68-position 0.8 mm Champ connector on far end of attached
8-ft cable. Video is transmitted at TTL levels, 1 byte wide plus hsync and
vsync. All camera parameters are accessed and controlled by the
workstation via I
Focus adjustment Focal distance from 3 in. to infinity with standard lens.
Microphone Built-in directional microphone and preamp produces a monaural,
single-ended line level signal.
