Abstract
Quality of a code provided in a test piece of a work is evaluated, using a sample processing function of a marker that gives the code to the work to present suggestion for setting of a processing condition to a user. Images picked up by a bar code reader are taken in to create a list of readable codes from these picked-up images, and images of these readable codes are displayed in a list. Tuning processing is performed to all the listed-up codes. In this tuning processing, the reading is tried while changing brightness, and a barometer of readability (easiness of decoding) in each of the reading trials is found to calculate a score indicating a level of reading stability based on a value of integral of this barometer, and this score is displayed as a numeric value and in a graph.
Claims10
A code quality evaluating apparatus that is connected to an optical information reading apparatus, and acquires images picked up by the optical information reading apparatus to evaluate quality of codes included in the picked-up images, the code quality evaluating apparatus comprising:
- an image taking-in device that takes in the picked-up images obtained by the optical information reading apparatus imaging the codes given to a work;
- a code extracting device that extracts the readable codes from the picked-up images;
- a score calculating device that performs reading trial to the codes extracted by the code extracting device while changing an imaging parameter, and calculates scores of reading stability of the extracted codes with respect to change of the imaging parameter, based on results of the reading trial;
- and
- a display device that displays the images of the codes together with the scores calculated by the score calculating device.
