5-16 Image Optimization
Line Density
Line density determines the quality and information of the image.
Adjust through the [Line Density] item on the touch screen.
There are 4 levels of line density provided: H, L, UH, M.
The higher the line density, the higher the resolution.
The higher the line density, the lower the frame rate.
Packet Size
This function is an indication of the ability to detect flow, which is used to adjust the
accuracy of color flow.
Rotate the knob under the [Packet Size] item on the touch screen to adjust the
value.
There are 3 levels of packet size available, 0 represents no packet size control and
the bigger the value the higher the sensitivity.
The higher the packet size, the more sensitive indication for low-velocity flow.
Adjusting the packet size may lead to frame rate changing.
Flow State
This function is used for fast image optimization.
Adjust through the [Flow State] item on the touch screen.
There are 3 levels provided to adjust: L, M, H.
Persistence
This function is to adjust the temporal smooth in Color mode to optimize the
image.
Rotate the knob under the [Persistence] item on the touch screen.
The system provides 6 levels of persistence adjustment, 0 represents no
persistence and the bigger the value the stronger the effect.
Smooth
This feature is used to reject noise and smooth the image.
Adjust through the [Smooth] item on the touch screen.
The system provides 6 levels of smooth function, the bigger the value the higher
the smooth.
