PURPOSE: To excellently extract the outline of, for example, only a tumor part to be extracted through binarization. CONSTITUTION: The image processor consists of an image input part 1 which uses an ultrasonic wave, etc., and obtains an image from its reflected wave, an outline detection part 2 consisting of a noise preremoval part 9 which removes noise from the image inputted from the image input part 1, an adaptive binarization part 10 which varies the level of binarization by small areas of the image, a noise postremoval part 11 which removes noise from the binary image, and an outline tracking part 12 which detects an outline in the binary image, a postprocessing part 3 consisting of a selection processing part 13 which selects the outline from information on an object to be extracted and an outline composition part 14 which generates an image for display, a monitor 4, a printer 5, and a filing device 6. |
