Abstract
A method and system is provided barcode scanning using image calibration for a captured image of a target barcode. The method comprises: receiving color image values for the captured image from a color image sensor; determining a set of coefficients for calibrating the captured image in dependence upon predefined sensor sensitivity profiles, the predefined sensor sensitivity profiles for defining spectral sensitivity values for the color image sensor for a range of predetermined wavelengths. Once the set of coefficients are obtained, they are applied to the color image values to obtain calibrated image values such as to provide color balancing of the captured image.
