<p>PURPOSE:To eliminate pseudo image and the like by containing to memorize in a memory the sea area generating pseudo image due to an object existing on a particular sea area as a pseudo sea area, and judging the image data indicated on the pseudo sea area to be a pseudo image when it is a new object. CONSTITUTION:An operater always is to input and contain in a memory with the use of a pseudo sea area input means 10 by obtaining from the screen the pseudo sea area where pseudo image is generated due to multiple reflection by surrounding structures or anchoring ships. Then an image data input means 6 takes out image data contained in an image memory 4 for each direction and outputs them to a pseudo image judging means 7. The means 7 judges whether the input data is new object and read the new data position in the case of new object. It then judges whether the position is that of image data memorized in the pseudo sea area in memory 9. When judged to be in the position, it is judged to be a pseudo image due to multiple reflection. The position of the memorized image data judged to be a pseudo image is set in a pseudo image recognition and addition means 11, and the position is notified to the follower 3.</p> |
