Abstract: PROBLEM TO BE SOLVED: To simply remove a ring artifact from the internal structure data of an inspection target.
SOLUTION: Reconstituted data is formed by reconstituting each projected image acquired by irradiating the inspection target arranged at a position not overlapped with the rotary shaft on a rotary means with X rays and the cross section data 31 vertical to the rotary shaft of the reconstituted data is subsequently acquired while an angle range θ1, wherein the data 7a of the inspection target itself is not present from a peripheral edge part to the rotary shaft 15, is detected in this cross section data 31 and the dummy cross section data 35 excepting the data 7a of the inspection target itself is formed with respect to an angle range (360°-θ1), wherein the data 7a of the inspection target itself is present, on the basis of the cross section data (genuine cross section data) 34 of the angle range θ1 wherein the data 7a of the inspection target itself is not present while the difference between the cross section data 31 of the reconstituted data and the cross section data 36 comprising the genuine cross section data 34, and the dummy cross section data 35 is calculated to obtain the cross section data 7a of the internal structure data of the inspection target itself.

Abstract: PROBLEM TO BE SOLVED: To improve the processing rate of labeling processing of a complicated binary image.
SOLUTION: In this device, when there is a position where different label numbers are adjacent on a label image labelled first when the binary image is labelled as a preprocessing for analyzing this image, focusing attention on the connection property, this set of connected label number is stored as a table, this table is reconfigured by regarding the connected numbers as the same label number, and the label image labelled first is relabelled on the basis of the finally formed table. According to this, an arithmetic processing for obtaining an ideal label image which is required in the analysis of a complicated image such as three-dimensional image can be more efficiently performed.

Abstract: PROBLEM TO BE SOLVED: To display a subject of a complicated shape with a sharp image in real time by providing a display means for displaying a synthetic image and a partial display means for displaying the subject nearly at the present time in a displaying range smaller than the synthetic image. SOLUTION: A microscope 1 photographs a subject 2 by means of a video camera 7 at its height to obtain image data based on a real image. A computer 9 fully focuses within the area of the partial display part of a monitor 5 to make a stereoscopic synthetic image to synthesize this stereoscopic image and a stereoscopic image formed before. Then, at the time of displaying the synthetic image of the subject 2 on the partial display part of the monitor 5, the computer 9 is not required to full-focus the whole displaying area from the beginning but required to full-focus only the area of a narrow and small partial display part again. Thus, the number of the times of full focusing is reduced and the subject of a complicated shape can be displayed with a sharp image in real time.

Abstract: PROBLEM TO BE SOLVED: To provide an X-ray tomograph for adjusting a location of an object to be tested in the direction other than rotational and vertical directions of a rotation table while X rays are radiated, identifying an observed region of the tested object, picking up a projected image of the object to be tested as a position after a location adjustment is maintained and having a micromotion means for not influencing concentricity of an air bearing if the air bearing is used for a rotation base. SOLUTION: The X-ray tomograph is provided with the rotation base for mounting the object to be tested 7 between an X-ray source and a two-dimensional detection means for picking up the projected image of the tested object and having a rotational axis perpendicular to a normal from an X-ray focus to a light receiving face of the two-dimensional detection means; a vertical direction micromotion mechanism for adjusting a location of the rotation base in the vertical direction. The micromotion means 9 has a horizontal direction micromotion location adjustment mechanism for adjusting a location of the rotation base on a surface perpendicular to the rotational axis. While the rotation base rotates and the projected image of the object to be tested 7 is picked up, a drive source 13 of the micromotion means 9 is wholly isolated from the rotation base.

Abstract: PROBLEM TO BE SOLVED: To display a sharp composite image fast by performing a process for taking pictures with a minute slip and a process for generating a composite image in parallel. SOLUTION: A photography step and a composition step are performed in parallel. For example, while (n-1)th image data are put in an input memory 10, image data which are already put in are processed by composition through a focus value memory 11, a focus computing element 11a, an old focus value memory 12, a comparator 13, a composition part 14, an all-focus image memory 15, and a video output part 16. While (n)th image data are put in the input memory 10, image data which are already put in are processed by composition through process systems 11 to 16. A computer 9 calculates focus areas by the data of an image of respective height in the depth direction, puts the focus areas of the image data together, and speedily displays a sharp stereoscopic image on a monitor.
