Abstract: A computer implemented method and system for processing a low quality captured image of a barcode of any type having a large amount of data is provided. An image processing application on a computing device acquires the captured image of the barcode, determines the type, for example, format, shape, etc., of the barcode in the acquired image of the barcode, and creates a gray barcode image from the acquired image of the barcode by gray shading over an entirety of the acquired image of the barcode. The image processing application modularizes the created gray barcode image based on the type of the barcode and binarizes the created gray barcode image based on the type of the barcode by comparing an average gray level intensity of each of multiple grids of pixels or by comparing gray level intensities of individual pixels in the created gray barcode image, with a predetermined threshold.
