Abstract: A target surface of a target object including portions having different curvatures is inspected by using an illuminating device and a camera that are fixed, a supporting device for supporting the target object such that its position and orientation are variable. The position and orientation of the target object are controlled as its image is obtained for a plurality of times. The position and orientation of the target object are controlled such that the image of any point on the target surface will be included in at least one of the images obtained by the camera.

Abstract: A vacuum control system allows the degree of vacuum in a vacuum vessel to be kept constant while removing vaporized components degassed into the vacuum vessel through a gas permeation diaphragm by stably introducing a very small amount of air into a vacuum exhaust path of the vacuum vessel. The vacuum control system controls the rotary power of a DC brushless motor, continuously controls displacement of a vacuum pump, and thus keeps the degree of vacuum in a vacuum vessel constant, by decompressing the inside of the vacuum vessel using an exhaust vacuum pump which operates with the DC brushless motor, monitoring the inside pressure of the vacuum vessel using a pressure sensor, and controlling a voltage applied to the DC brushless motor on the basis of an output signal resulting from measurement of the inside pressure of the vacuum vessel by the pressure sensor.

Abstract: A surface of a work to be inspected is irradiated with an illumination unit for a coaxial incident illumination and an illumination unit for an oblique incident illumination driven to take its image by a camera at the same time. Each of the illumination units and comprises light sources emitting color lights R, G and B, respectively. One of the three kinds of light sources is lighted in the illumination unit and one or two of the light sources which are not lighted in the illumination unit are lighted in the illumination unit.

Abstract: An apparatus reproduces an image recorded with a difference between adjacent frames at at least one scene change point and scaled-down images for identifying each scene change point. A time-length-determining device determines the length of time to display the scaled-down images, the length of time corresponding to the frame length of a screen of a display device in which the image is displayed. An image-number-determining device determines the number of scaled-down images to be displayed during the length of time. A threshold-value-setting device sets a threshold value for the differences recorded during the length of time to allow a number of scaled-down images corresponding to the number of scaled-down images determined by the image-number-determining device to be extracted.

Abstract: Light sources emit irradiation lights respectively, so that edge parts of mutual irradiation areas (inspection areas) are superposed one another. The imaging apparatus receives regular reflection lights and generates two images corresponding to each of the light sources. A main control part combines two images and determines presence/absence of a defect. By irradiating an inspected surface A with the irradiation lights from mutually different directions, a position of an area showing the defect in each image is slightly deviated. Therefore, even if a dimension of an area showing the defect is small in each image, by superposing two images one another, the dimension of the area showing a defect part becomes large in the image after composition. Thus, an accuracy of defect detection on the edge part of the inspection area can be improved.

Abstract: An image processing method and an image processing apparatus are disclosed, in which curved linear objects and uneven linear objects as well as rectilinear objects can be detected easily and accurately. Edge pixels P1 extracted from a gray-scale image to be processed are sequentially considered to search for an edge pixel having an opposite direction of density gradient to each of the edge pixels P1 within the range of a predetermined length W along the direction orthogonal to the edges. Once an edge pixel P2 meeting these conditions is extracted, a line segment having a length L is set extending in the direction C parallel to the edge of the edge pixels P1 from an intermediate point Q between the extracted edge pixel P2 and the edge pixel P1 under consideration.

Abstract: A pattern data transfer circuit capable of decreasing the number of transfer of pattern data and of shortening the entire transfer time as a whole. A chip selector circuit generates pin group data representing tester channels contained in respective pin groups on the basis of pin groups such as “ADDRESS” and adapter board data corresponding to the tester channels, and it validates only a chip select signal corresponding to the tester channel shown by the pin group data in the case of transfer of “I/O” data and “Strobe Mask” data, and also validated either chip selector signal CS corresponding to the tester channel in the case of transfer of “HiLo” data. A CPU extracts respective patterns of the selected pin group from pattern data and transfers the extracted patterns to all the pattern memories.
