PROBLEM TO BE SOLVED: To enable a host apparatus to treat a state of radio connection with another device via a radio communication interface as a state of an external storage device. SOLUTION: A radio communication device includes: a host connection interface which is connected to a host apparatus and receives commands input from the host apparatus; a radio communication interface which performs radio communication with another radio communication device; and a control unit which controls operation of the host connection interface and the radio communication interface. The control unit controls the host connection interface to output device information indicating that the device is a peripheral device for accessing a storage medium to the host apparatus, in response to a command indicating inquiry about information regarding the device.

Abstract:
PROBLEM TO BE SOLVED: To prevent a double image by a false focal point in a reconstituted image of acquired projection data. SOLUTION: The X-ray focal point 2 on a target is set as a vertex, an inspected body 5 mounted to an inspected body rotating mechanism is rotated between an X-ray source 1 and a two-dimensional detector and about the rotation axis of the inspected body 5 crossing rectangularly to the vertical line that is extended from the focal point 2 of the X-ray source 1 forming a conical first radiation field 2a of which center axis 4 is substantially coaxial to a thermionic current emitted from a cathode to the two-dimensional detector of which initial attitude is the detection surface substantially orthogonal to the thermionic current emitted from the cathode, and the projection data of the inspected body 5 is obtained. A this time, the whole or a specific part of the inspected body 5 is moved to a region that is not affected by a second radiation field 3a by a false focal point 3 of the first radiation field 2a by the original X-ray focal point 2, and the projection data of the inspected body 5 in each angle phase is obtained.

Abstract:
PROBLEM TO BE SOLVED: To propose an imaging technique for computerized tomography, which rapidly computes the optimal parameter used in a reconstruction computation process for internal structure data of a body to be inspected and can obtain the internal structure data with high sharpness by using the parameter. SOLUTION: The system is provided with an X-ray source, a two-dimensional detecting means and a rotatable base section for the inspected body disposed between the X-ray source and the detecting means. The internal structure data are reconstructed from the projection images of the inspected body obtained at every angular displacement, and pixel data on a line perpendicular to the axis of the rotation of the inspected body are read from the projection images of the respective angular displacements, and an offset value of the rotation axis of the inspected body from the perpendicular line, which is dropped from the X-ray focal point to the detecting means, is set as the parameter used in the reconstruction computation process, and the pixel data at respective angular displacements are subjected to the reconstruction computation process while changing the parameter to obtain a plurality of images, and sharpness values are calculated respectively. When the maximum sharpness value is detected, the value of the parameter is specified as the optimal offset value of the rotation axis, and the internal structure data of the inspected body are reconstructed in consideration of the optimal offset value of the rotation axis.

PROBLEM TO BE SOLVED: To remove an influence of a change with the lapse of time of a focal position in a radiation such as an X-ray emitted to a specimen, by simple constitution, and to enhance fineness of an internal structure data calculated by reconstitution calculation. SOLUTION: In this computer tomography having a radiation source 1, a two-dimensional detection means 2 for picking up a projection image of the specimen 7, and a rotary base part arranged between the radiation source 1 and the two-dimensional detection means 2, and for mounting the specimen 7 to be rotated at a prescribed angle displacement, to reconstitute the internal structure data, based on the projection image of the specimen 7 image-picked up in every angle displacement, the focal position in an optional time of the radiation is set as a reference focal position, the focal position after the lapse of a prescribed time is detected after setting the reference focal position, a variation between the reference focal position and the focal position after the lapse of the prescribed time is calculated, and a positional relation between the radiation 1, and the specimen 7 and the two-dimensional detection means 2 is moved based on the variation.

Abstract:
PROBLEM TO BE SOLVED: To measure a height on the basis of the picked-up image screen of objects such as electronic parts or the like by calculating a focus value by processing images and detecting a focus position from the Z-direction change of the focus value. SOLUTION: A subject 11 whose image is to be picked up such as a mounting board or the like to be inspected is placed on a stage 12. An image pickup means 13 picks up the image of the subject 11 placed on the stage 12 in the perpendicular direction (Z direction) from above. A moving means 14 moves and adjusts the image pickup means 13 in the Z direction relatively to the stage 12. A computer 15 controls the stage 12, image pickup means 13 and moving means 14, and moreover, measures a height of the subject 11 based on an image pickup signal from the image pickup means 13. A focus value is calculated from a picked image screen of the subject 11 by an inspecting apparatus which inspects a shape of the subject 11 from the picked image screen, and a focus position is obtained. The height of the subject 11 is measured accordingly.
Abstract:
PURPOSE: To obtain an apparatus wherein a user can process an image of an object with a simple procedure by acquiring and storing images of the object and extracting pixels whose brightness of red, green and blue of an arbitrary region of interest of a binary-coded image is in a specified range. CONSTITUTION: A CCD camera 2 of an image acquiring means 20 acquires images of an object and stores them in an image memory 14. A processing means 25 comprising a system controller 7, an image processing control CPU 16 and an image processor 15 binary-codes an arbitrary region of interest of the stored image and extracts pixels whose brightness of red, green and blue in the region of interest of the binary-coded image is in a specified range to determine whether or not the image of the object is good. The pixels whose brightness of red, green and blue is in the specified range are extracted and displayed on a display monitor 5. A set processing monitor 4 is provided for a user to select and set these processing contents.
