Abstract: Camera-based services are provided to a user of a portable communication device by recognizing text contained in an image. An image of an environment is captured using a camera within the portable communication device so as to obtain image data. The image data is processed such that text data is recognized and extracted from the image data. Data related to the text data is then output in a form recognizable by a user of the portable communication device. The text data can be processed on the portable communication device to obtain the data related to the text data. Alternatively, the processing is performed by a processing unit external to the portable communication device. Translated and audio versions of the text data are output to the user. One camera-based service provides price and product information related to a product described in an image captured by the camera.

Abstract: 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.

Abstract: A reading device for blind or visually impaired persons for recognizing and reading text passages comprises an image capturing unit being configured to capture an image of an environment of a blind or visually impaired person and to output image data corresponding thereto, an image processing unit being configured to process the image data such that text is recognized and extracted from the image data and to output text data corresponding thereto, a text outputting unit being configured to output data corresponding to the text data in a form noticeable or convertable to be noticeable by the blind or visually impaired person, and a housing comprising a first part and a second part, the first part having the image capturing unit attached thereto and the second part accommodating the image processing unit and the text outputting unit.
