Abstract

Provided is an image processing apparatus and an image processing program which are capable of selectively and readily acquiring a geometrical physical quantity of a desired measuring portion. An object image is displayed based on object image data, and a measuring portion designating image corresponding to a specific portion of the object image is displayed based on designating image data. By operation of an operation part by a user, the displayed measuring portion designating image is moved relatively to the object image. When the measuring portion designating image is moved to a specific portion of the object image, a geometrical physical quantity of a measuring portion of the measuring object, previously set so as to correspond to that specific portion, is measured.

Claims

1. An image processing apparatus for a magnification observation apparatus including an object lens, and an imaging device optically coupled to the object lens, and configured to acquire an image representing an object to be measured as an object image, comprising:

a display configured to display the object image, and to display, on the object image, a measuring portion designating image corresponding to a specific portion the object image;

a storage configured to store a preset positional relation between the measuring portion designating image and a plurality of detecting regions at which a predetermined characteristic portion including an edge part is detected from the object image, and to store a measuring condition; and

a processor configured to perform a manual movement of a position of the measuring portion designating image relatively to the object image in response to a manual input, to detect the edge part as the predetermined characteristic portion at each of the plurality of detecting regions from the object image based on the position of the measuring portion designating image relatively to the specific portion of the object image, and to calculate a geometrical physical quantity based on the measuring condition and the edge part detected as the predetermined characteristic portion and wherein the process part is operated so that, when a distance between the measuring portion designating image and the specific portion of the object image falls within a predetermined range by operation of the operation part, the measuring portion designating image is moved so as to make a position of the measuring portion designating image agree with a position of the specific portion of the object image.

2. The image processing apparatus according to claim 1, wherein the geometrical physical quantity includes at least one of a length and an angle.

3. The image processing apparatus according to claim 1, wherein the measuring portion designating image includes a specific portion of an image of an object which is identical or similar to the object to be measured.

4. The image processing apparatus according to claim 1, wherein the measuring portion designating image includes a diagram corresponding to the specific portion of the object image.

5. The image processing apparatus according to claim 1, wherein the manual movement includes an adjustment of a position and an orientation of the measuring portion designating image.

6. An image processing method for a magnification observation apparatus including object lens, and an imaging device optically coupled to the object lens, comprising:

acquiring an image representing an object to be measured as an object image by the imaging device;

storing a preset positional relation between a measuring portion designating image and a plurality of detecting regions at which a predetermined characteristic portion including an edge part is detected from the object image;

storing a measuring condition;

displaying the object image;

displaying, on the object image, the measuring portion designating image corresponding to a specific portion of the object image;

performing a manual movement of a position of the measuring portion designating image relatively to the object image in response to a manual input;

detecting the edge part as the predetermined characteristic portion at each of the plurality of detecting regions from the object image based on the position of the measuring portion designating image relatively to the specific portion of the object image; and

calculating a geometrical physical quantity based on the measuring condition and the edge part detected as the predetermined characteristic portion and when a distance between the measuring portion designating image and the specific portion of the object image falls within a predetermined range by operation of the operation part, the measuring portion designating image is moved so as to make a position of the measuring portion designating image agree with a position of the specific portion of the object image.
