Abstract
A barcode evaluation device is configured to conduct an evaluation, which involves determining whether or not a barcode image is displayable on an image display device and determining whether or not the barcode image is readable with a barcode reading device. The evaluation is conducted based on specifics of the barcode image, specifications of the image display device, and specifications of the barcode reading device without actually displaying and reading the barcode image.
Claims14
A barcode evaluation device, which is configured to:
- conduct an evaluation, which involves determining whether or not a barcode image is displayable on an image display device and determining whether or not the barcode image is readable with a barcode reading device, the evaluation being conducted based on specifics of the barcode image, specifications of the image display device, and specifications of the barcode reading device without actually displaying and reading the barcode image;
- generate a coordinate system that has, as coordinate axes, values representing the specifications of the image display device;
- map, onto the coordinate system, as an area, a range of specifications required for the image display device in order to display a given barcode image so that the given barcode image is readable with a given barcode reading device, and plot, on the coordinate system, as a point, coordinates that correspond to the specifications of the image display device to be evaluated;
- and
- produce, by mapping the area and plotting the point, in a visible manner, whether or not the specifications of the image display device to be evaluated are within the required specification range, and, when the image display device specifications are outside the required specification range, how far off the image display device specifications are from the required specification range.
