Abstract
An image processor acquires an image including a desired portion of an object to be examined. An image memory temporarily stores the acquired image, and an outline is extracted from an area of interest from the desired portion of the object. The outline is extracted by dividing the image stored in the image memory into plural areas using parallel lines, and a threshold value is set for each of the plural divided areas. Points having values exceeding the threshold values are connected.
