Publication number: 20120185221Abstract: 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.Type: ApplicationFiled: October 25, 2011Publication date: July 19, 2012Applicant: OMRON CORPORATIONInventors: Hiroyuki Mori, Katsuki Nakajima, Hiroshi Tasaki

Patent number: 7475822Abstract: 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.Type: GrantFiled: December 6, 2005Date of Patent: January 13, 2009Assignee: OMRON CorporationInventors: Gaku Shiramizu, Takuya Murata, Katsuki Nakajima

Patent number: 6918539Abstract: 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.Type: GrantFiled: June 16, 2003Date of Patent: July 19, 2005Assignee: Omron CorporationInventors: Katsuki Nakajima, Koji Sakacho, Takuya Murata
