摘要： PURPOSE:To provide a pattern appearance inspection device conforming to such an inspection criterion as corresponding to lead width, and having high reliability even against dislocation or the like. CONSTITUTION:An electronic component as an inspected part 1 is illuminated with the lighting device 2 of an image input section 4, and photographed with a CCD camera 3. The pickup image of the camera 3 is read in as a variable-density image 5 and converted to a binarized image 7 in a binarized image processing section 6. Thereafter, a fine lining processing section 8 gives a core line image 10 indicating a core line position, whereas a distance conversion section 12 gives a distance value image 11 indicating the value of a distance from the background. The images 10 and 11 are, then, entered in an information calculation section 12, and information on line breadth and characteristic at the core line position is calculated for storage in a memory 14. Furthermore, a reference data memory section 16 saves the reference data of the line breadth at each core line position, and a comparison and judgement section 15 having CPU 13 makes a comparison between each line breadth of measurement data, by use of an allowable value proportional to the line breadth of reference data within the range preliminarily established on the basis of a target point, thereby making judgement about the quality of a lead pattern.

摘要： PURPOSE:To restrict the number of notified defects to minimum by integrating extracted defective pixels showing the distance therebetween not larger than predetermined (m) pixels into one group, and operating and notifying the representative coordinates of the group. CONSTITUTION:A wiring pattern on a printed board is illuminated by a scattering illuminating device. The dark-and-bright image obtained by an image input means 101 provided with a CCD camera is compared with a predetermined threshold value by a binarizing means 102, so that the image is converted to a binary image wherein a part of the wiring pattern is expressed by 1 and a part of a base material is represented by 0. The binary image is compared with a standard pattern in a defect extracting means 103, and a defect of the wiring pattern is extracted. As a result, an image from which the defect is extracted is output. In a defective pixel integrating means 104, the connecting characteristic of a target pixel with the peripheral defective pixels is determined if the target pixel is defective. When the target pixel shows the connectivity with the peripheral defective pixels, the pixels are treated in one group and the coordinates of the group are registered. The connected pixels are the pixels the distance of which is not larger than predetermined (m) pixels. When the extracted images are completely scanned, the representative coordinates of each group are calculated and notified.

摘要： PURPOSE:To attain high speed arithmetic processing and to improve a texture of a highlight and dark area so as to obtain high definition reproduced picture by provid ing an input correction means, a multi-value processing means, a differential arithmetic means and an error distribution revision means or the like. CONSTITUTION:An input level Ixy inputted from an input terminal 4 and a correction error level exy are corrected by a correction means 5 and the result is outputted to a multi-value processing means 7. The means 7 compares the inputted correction level with plural threshold levels, applies multi-value processing to the result to a difference arithmetic means 8. The means 8 outputs a multi-value processing error being a difference between an inputted multi-value processing level and a 2nd input correction level to an error distribution revision means 11. Then the means 11 combines plural dither matrix threshold level with other dither threshold level taking a threshold level of the multi-value processing error diffusion method as the center and rearranges the result to improve the texture in the highlight and dark region. Moreover, the picture quality is controlled by the selection of a coefficient of a correction error level exy and to attain high speed calculation by bringing the coefficient to 1/2 or 1-1/2 .
