Pixel rate: It is used to set a parameter to supply correct current to PLL-oscillator. This
parameter is set according to resolution and horizontal frequency.
Save image to web: Leave the default setting "Saved as JPEG" unchanged.
Charge Pump Current: 0.5 mA fixed
Video Clock Polarity: Through fixed
Counter Clock Selection: 49 MHz fixed
Color mask bit: "Color mask bit" has a big influence on the size of the generated
radar-image. If video is noisy, the image size becomes large. Color mask is used to
filter "noise." If radar-picture is very noisy, reduce the Color Mask Bit to reduce
image-size. The smaller the color mask bit, the less number of different colors.
21-bit: each RGB value is masked with 0xFE (254 – decimal).
18-bit: each RGB value is masked with 0xFC (252 – decimal).
15-bit: each RGB value is masked with 0xF8 (248 – decimal).
12-bit: each RGB value is masked with 0xF0 (240 – decimal).
9-bit: each RGB value is masked with 0xE0 (224 – decimal).
6-bit: each RGB value is masked with 0xC0 (192 – decimal).
Sample rate: 15 seconds fixed
Interlace type:
When the video image is interlace, select "Interlace" sampling mode. In Interlace mode,
the even pixels are sampled on one frame and odd pixels are sampled on the other
frame.
Pulse Position Interlace Detection: You need to set this parameter in the case of
interlace signal. You should set that this parameter is a quarter of horizontal scanning
term.
Pulse Width Interlace Detection: You need to set this parameter in the case of
interlace signal. You should set that this parameter is a half of horizontal scanning term.
Interlace Field Polarity: You need to set this parameter in the case of interlace signal.
Normally positive fixed.
Sync type:
Selects the type of video sync signal. Some video signals include embedded composite
sync rather than separate horizontal and vertical sync signals, typically sync on green.
Some video signals include embedded composite sync rather than separate horizontal
and vertical sync signals. Options are Separate, Composite (embedded in video) and
Sync on Green (SOG, Embedded in Green-analog-signal in RGB-lines).
Pulsewidth for VD detection: You need to set this parameter in the case of
composite sync (Sync type = Hsync or Vsync) for separating HD and VD. You should
set that this parameter is twice of Hsync width.
