Advanced Camera Settings
The Advanced camera settings button lets you fine-tune the
configuration for your specific camera.
Figure 5-7 shows the advanced camera settings dialog box.
Figure 5-7. Advanced Camera Settings
All settings except Sync Detect and Aspect Ratio Correction are
measured in pixels from the beginning of the horizontal
synchronization pulse. The Start parameter specifies the rising edge of
the internally generated pulse while the Stop parameter specifies the
falling edge of the pulse.
Advanced camera settings include:
•
HSYNC Start and HSYNC Stop—These settings define the
positioning and duration of the internally generated horizontal
(line) synchronization pulse. To generate a negative edge at
position zero, set the HSYNC Stop value to 0. The width of the
pulse in samples is defined by the difference in pixels between
HSYNC Start and HSYNC Stop and is typically 4.7 µs for
standard video.
