Image Optimization 5-5
Operation Adjust through the [Line Density] item in the soft menu.
There are three levels of line density available: M, H, L, UH.
Effects The higher the line density, the higher the resolution, and the lower the
frame rate.
Dynamic Range
Description This function is used to adjust the B image resolution to compress or
expand the gray display range.
The real-time dynamic range value is displayed on the image parameter
area in the upper left corner of the screen.
Operation Adjust through the [Dyn Ra.] item in the soft menu.
Or adjust it in the image parameter area.
The adjusting range is 30-240dB in increments of 5dB.
Effects The more the dynamic range, the more specific the information, and the
lower the contrast with more noise.
iClear
Description This function is used to increase image profile, so as to distinguish the
image boundary.
Operation Adjust through the [iClear] item in the soft menu.
The system provides 5 levels of iClear effects adjustment, off represents
no iClear is turned on, and the bigger the value the stronger the effect.
Effects The bigger the value the more clearly the profile of the image.
Persistence
Description This function is used to superimpose and average adjacent B images, so
as to optimize the image and remove noises.
Operation Adjust through the [Persistence] item in the soft menu.
The system provides 8 level of frame average adjustment, the bigger the
value the stronger the effect.
Effects Persistence can remove image noise to make details to be clearer.
Impacts Persistence increase may lead to signal missing.
Invert /Rotation
Description This function provides a better observation for image display.
Invert(L/R
Flip)
To invert the image horizontally or vertically.
Click [L/R Flip] in the menu or the soft menu to invert the image.
Rotation Rotate the image through the [Rotation] item in the menu or the soft menu.
Image can be rotated by the manners in angle of 0°, 90°, 180°, and 270°.
When the image is rotated at the angle of 90° or 270°, the depth scale is
displayed on the upper part of the screen.
When you invert or rotate an image, the “M” mark will change its position correspondingly
on the screen; the M mark is located in the upper left corner of the imaging area by
default.
