The A6700sc camera has a 14-bit digital output. However, the analog output is only 8-bit. An
Automatic Gain Control (AGC) algorithm is used to map the 14-bit digital to the 8-bit analog data. The
Video Tab provides controls related to optimizing the Analog video output. These controls affect
only the analog video. Figure 4-16 shows a flow chart of the analog video process and how the
parameters of this screen are used.
Analog Video Setup Options
Format
NTSC: 640x480, 30Hz interlaced, color based on Palette selection,
(Note: top and bottom 16 lines are truncated when full images are
displayed. The Analog window can be adjusted +/- 16 rows using the
Setup>>Window Tab)
PAL: 640x480, 25Hz interlaced, color based on Palette selection
Note: When camera frame size is smaller than video frame size, black
borders are added to maintain standard video output sizes
Overlay Enables the analog video overlay.
Filter Rate Rate at which AGC is computed (1 to 20 Hz)
Dampening
Rate at which AGC is allowed to change. This will keep the AGC from
responding rapidly to fast tridents changes. Specified as a fraction from
0 to 1. This fraction is used as a weighting factor for the current AGC vs.
the newly computed AGC.
