Customizing barcode images for particular displays

摘要

Techniques for ensuring maximum readability of barcodes displayed in pixel displays. The techniques use the characteristics of the pixel display to determine the form of the barcode in the pixel display. Determination of the form includes determining a size of the barcode winch renders the barcode's elements easily readable by a barcode reader and a shape, and or orientation of the barcode in the display which permits the entire barcode to be displayed in the display. Additionally, in a barcode with redundant information, the amount of redundant information may be reduced in the displayed barcode. The techniques may be applied to both one-dimensional and two-dimensional barcodes.

1. A method of displaying an image of a barcode comprising barcode elements in a pixel display belonging to a mobile device, the method comprising the steps of:
receiving, in the mobile device, data to be encoded as barcode information; determining a minimum element size, in pixels, for each barcode element encoding the received data on the pixel display such that an image form of the barcode is readable by a barcode reader when displayed in the pixel display; and in response to receiving the data to be encoded and the determined minimum element size, causing the image form to be generated and displayed in the pixel display, such that each barcode element in the barcode is an integer multiple of the minimum element size for the display of the mobile device, such that the barcode reader can extract the data encoded by the barcode elements as displayed on the display.
