  • Publication number: 20120185221
    Abstract: Suitability of determination standard value for intermediate inspection is determined. A correlation between measured values X for intermediate inspection and measured values Y for final inspection is derived. For each of calculation target points on X-axis, a distribution pattern of measured values Y is specified for measured value Xn of the point based on the correlation, and probabilities of a range determined to be non-defective by determination standard value of final inspection and a range determined to be defective that are included in the distribution are calculated. For each of the ranges of measured values X determined to be non-defective and defective based on the determination standard value of the intermediate inspection, a degree of consistency and a degree of inconsistency between results of inspections are determined using the probabilities. Suitability of the determination standard value is determined based on the two degrees.

  • Patent number: 7475822
    Abstract: An optical data code reader includes an illuminator device for illuminating an optical data code to be read out, an image-taking device for taking an image of this optical data code, a readout device for decoding the optical data code by processing image data generated by the image-taking device and an adjustment device for carrying out an adjustment process. The adjustment device adjusts an illumination condition of the illuminator device and/or an image-taking condition for the image-taking device such that the image data become suitable for being read out. The adjustment device serves to set areas on image data outputted by the image-taking device, to extract a variation amplitude of brightness in each of the areas and to carry out the adjustment process by using the image data of at least one of the areas in which the extracted variation amplitude is greater than a specified threshold value.

  • Patent number: 7278573
    Abstract: A device for reading out an optical code includes a camera, an image memory for storing images taken by this camera, and an image processor for decoding an optical code contained in an image taken by the camera. A plurality of images are obtained continuously with the camera under specified image-taking conditions in response to a specified image-taking command, and the obtained images are stored on the image memory. The images stored in the image memory are sequentially selected one at a time in a specified order, and the image processor makes an attempt to decode an optical code contained in the selected image. Results of decoding are outputted if the attempt to decode any of the stored images is successful. The interval at which the images are taken is changed according to the number of images successfully decoded taken continuously in the past.

  • Patent number: 6918539
    Abstract: A two-dimensional code reader repeats a cycle of ordinary code-reading processes such as taking an image of an optical data code, extracting a two-dimensional code from the image and decoding optical data of the two-dimensional code in the image. A specified evaluation value for the optical data code is obtained from the results of processes carried out prior to the decoding step and stored if the decoding is done successfully. Data which show the changes in the evaluation value with time are displayed. The evaluation value may be compared with a specified warning level and a warning output is made, depending on the result of the comparison.
