US 2013/0170765 A1 · METHOD FOR RESTORATION OF BLURRED BARCODE IMAGES

Abstract

The present invention relates to the field of human interaction with mobile devices, more specifically the interaction done by the automatic recognition of barcode images captured by the camera integrated in portable devices, particularly mobile phones, smartphones, Personal Digital Assistants PDAs, portable digital camera, among others. The present patent application relates to a method to effect the reading of barcodes by means of portable devices with digital cameras. The present invention provides a method to restore barcode images damaged by the blurring effect due to the lack of focus of the captured images with low cost cameras with fixed focus. The proposed method treats the image of barcodes in order to enable correct decoding of its content.

Method for restoring images of blurred barcodes comprising the steps of:

Capturing the image with the barcode (1210), in which a picture shot by the camera is selected and sent for decoding;
After capturing the frame, starting the step restores the image (1211), in which it selects one OTF in the database and makes deconvolution;
After image restoration, initiating the step of decoding barcode (1212) which receives the image of the barcode restored and tries to perform the decoding thereof, said process being divided into sub-steps that perform image processing to return the numbers represented by the barcode present in the image;
When the decoding a barcode is successfully performed, then start step “displaying the result” (1213),
