Sensor

512 x 480 NTSC Color CCD, 1/3” format.

Standard lens

F2.0, 6 mm 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 422 YCrCb pixels with 1 byte luminance followed by 1-byte chrominance, on a 24.5 MHz interface clock.

Automatic Gain Control

Automatic Gain Control adjusts gain to achieve average output 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

1 W @ 5 V (200 mA), 1 W @ 12 V (80 mA), and 12 mW @ -12V (1 mA) 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 I²C.

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 I²C. Workstation provides 5 V power.

Focus adjustment

Focal distance from 3” to infinity with standard lens.

Microphone

Built-in directional microphone and preamp produces a monoaural, single-ended line level signal.
