3.10 Digital Video Tab

Tau offers a LVDS interface digital output that can be configured in four modes. Changing these
modes will have no effect on the analog (NTSC or PAL) signal. In order to access the digital
output, you must use an advanced interface as described in Chapter 4, Tau Digital Data
Channel. See the Tau Electrical Interface Control Document (102-PS220-41) for information on
how to access digital video for LVDS, BT 656, and CMOS.
1. Select Video
The settings that affect the digital data stream are described below.
Off: The digital data stream coming from the Tau camera is turned off.
8-bit: Data from the 320x240 (NTSC) or 320x256 (PAL) video pixels is provided after
application of the current Automatic Gain Control (AGC) and Dynamic Detail
Enhancement (DDE). The 8-bit data is essentially a digital version of the same data
provided on the analog video channel.
14-bit Filtered: Data from 322x256 pixels is provided prior to video processing modes
in the 8-bit data described above. The 14-bit data is the filtered data to include the
Dynamic Detail Enhancement (DDE) and will appear gray when saving 16-bit TIFF files.
14-bit Raw: Data from 322x256 pixels is provided prior to all video processing and
does not include the Dynamic Detail Enhancement (DDE). The 14-bit data is the 'raw'
data and will also appear gray when saving 16-bit TIFF files.
Note
AGC mode will affect the digital data output if Camera Digital Output mode is set to 8-bit data.
