Title: Device and method for processing image
Inventor: YUASA MAYUMI
IPC: G06T1/00
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To easily judge whether an extracted contour is matched with an object or not by displaying the extracted contour while overlapping it on the object of an image, and making that display contour into dotted line or contour line at a desired section at least. SOLUTION: An image input part 1 inputs the source image of an ultrasonic image or the like. Then, a contour extracting part 2 extracts the contour of the object from the source image received from this image input part 1. By a display area determining part 3, the section to be displayed is determined from the extracted contour area, and a display image generating part 4 generates a display image by overlapping the display area in the contour area determined by the display determining part 3 on the source image previously inputted by the image input 'part 1. Then, an image display part 5 displays the image provided by this display image generating part 4. As a result, since the displayed image becomes an image overlapping the respective sections of the contour line with the source image, it is easily verified whether the contour line is matched with the object or not.
