The present invention relates to a method for aligning a camera sensor to significant data which is text or barcode data to be recognized comprising the steps of:—capturing an image of the significant data by means of the camera sensor; —detecting a predominant alignment line of the significant data and detecting an angle thereof in relation to a horizontal line of the captured image; —determining image sections within the edge and line enhanced image which contain most likely significant data lines; —selecting a representative image section out of the determined image sections which is aligned with the predominant alignment line; —capturing a following image of the significant data; tracking the representative image section and determining the predominant alignment line out of the representative image section to achieve a fast calculation and audio or tactile feedback of the alignment quality to the user.
