Tau User's Manual
8-bit: Data from the 320 × 240 (NTSC) or 320 × 256 (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 324 × 256 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. See "Tau Digital Data Channel" on page 4-1.
14-bit Raw: Data from 324 × 256 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. See "Tau Digital Data
Channel" on page 4-1.
XP Mode Select
The Tau camera has 18 XP pins on the 50-pin Hirose connector. The XP mode uses a
number of these pins to output parallel digital image data.
BT656: The BT.656 parallel output is a common interface which will drive many LCD
displays. The data is digitally encoded NTSC/PAL video and will have AGC, DDE,
symbols, and color included.
CMOS: The CMOS interface is a parallel output that allows the user to access 8-bit
AGC corrected data or 14-bit data. The signal levels are 0 - 3.3 V CMOS logic and are
intended to drive boards mounted directly to the Tau camera. CMOS is not intended to
drive a cable. An XP-board reference design is available upon request.
