摘要： PROBLEM TO BE SOLVED: To discriminate existence of a notch, by forming a template for expressing characteristically a part where brightness is changed on a notch edge part, and by executing density pattern matching between the template and an inspection image. SOLUTION: A semiconductor package is photographed by a television camera, and the circumference of a notch is dragged by using a mouse, and brightness information of each one pixel is recorded as a template. In a figure (B), a thickly shaded part is a notch part, and a dark part, a thinly shaded part is the package surface of a gray part. As for a part where a character is written inside the notch, an operation of the degree of coincidence by density pattern matching is not executed and an operation of pattern matching is skipped, therefore a template shown by a figure (C) is obtained, and the inside of a quadrangle shows the range of the template and a central white part shows a part where the operation is not executed. As a countermeasure against incapability of recognition of the notch part because of having the same brightness as the semiconductor package surface, the thickly shade part in the figure (C) is narrowed as much as possible by using the fact that the shaded part of a step is blackened for a while.

摘要： PURPOSE:To detect errors and positions of parts on a printed circuit substrate, by making a light and darkness boundary line by a projector on the surface of the printed circuit substrate and obtaining the data of a profile line by photographing the parts on the substrate which is passing the boundary line by a video camera. CONSTITUTION:A printed circuit substrate 1 which is transported is arranged so that the right side of a light and darkness boundary surface Z including an optical axis which is vertical to the substrate 1 is projected by a slit 21 of a projector 2 and the left-side light is shielded. A television camera 3 is arranged so that the optical axis forms 90 deg.-theta angle to an irradiated area Za side against the boundary surface Z, and a scanning direction is arranged so that a horizontal amplitude direction forms right angles to the direction of a boundary line Y between an irradiated area Za and a light shielded area Zb made on the substrate 1. By operating the profile line data of the Y axial direction obtained from a length of the light and darkness part of the Y axial direction, an outer profile in a width direction is decided. Then, the substrate 1 is moved to a prescribed distance and the profile line data in an X axial direction is obtained and the outer profile of a part 13 in the thickness direction is decided. The shape of the part 13 is specified from these data.

摘要： PURPOSE:To improve the resolution in position measurement with an ordinary television camera by reading the information of the brightness of the image stored in a variable density image memory, and adding the ratio of the differ ence of the brightnesses obtained in the changing range of the brightnesses between the images, which are picked up with a television camera, to the lower coordinate values. CONSTITUTION:A variable-density image memory 18 receives and stores the image signal of a digitized object, which is picked up with a television camera 11, from a data signal line through a buffer 12, an A/D converter 13 and a switch 21. A computer 19 is connected to a counter 17 through a switch 20 from an address signal line and connected through the switch 21 from the data bus signal line. The switches 20 and 21 are switched only when the computer 19 accesses the memory 18, and the brightness information of the picked up image is read out. The difference of the brightnesses of the images on both sides holding the average brightness between the pixels is made to be the denominator, the difference between the brightness of the lower pixel of the coordinate value and the average value is made to be the numerator and division is performed. The result is added to the lower corrdinate value.
