Image Threshold & Contrast:
Using the red handle on the upper and lower part of the colour pallet allows the data
threshold and contract to be adjusted.
This allows the sonar image to be adjusted to suit the requirements of the application at
hand:
•
Weaker targets can be removed from screen by raising the lowest red handle.
•
Higher contrast can be provided by lowering the uppermost red handle.
Several examples of adjusting these variables on the same image are shown below:
Standard setting – all data shown
Upper Red Handle lowered - increasing
contrast
Lower Red Handle raised – removing
weaker targets
