Abstract

A wireless telecommunications terminal is provided comprising a digital camera and a processor. The digital camera is configured to take a digital photograph of an item showing a character string. The processor is configured to receive data of or relating to the character string read by an optical character recognition (OCR) reader in the digital photograph information, and to process said data.

Claims

1. A wireless telecommunications terminal comprising a digital camera and a processor,

the digital camera being configured to take a digital photograph of an item, the item showing a character string, and

the processor being configured to receive data of or relating to the character string read by an optical character recognition (OCR) reader in information of the digital photograph and to process said data.

2. A terminal according to claim 1, comprising the OCR reader.

3. A terminal according to claim 1, wherein the terminal comprising a wireless telecommunications transmitter and wireless telecommunications receiver, the transmitter being configured to transmit the information of the digital photograph, and the receiver being configured to receive the data of or relating to the character string from the OCR reader and to forward said data to the processor.

4. A terminal according to claim 1, further comprising a display, in which the processor is configured to process the data by providing said data to the display.

5. A terminal according to claim 1, including an authorisation stage configured to enable a user of the terminal to indicate to the processor that the character string should be processed further.

6. A terminal according to claim 5, in which the character string is a telephone number, the authorisation stage enables the user to indicate that a call connection to a terminal associated with the telephone number should be made, and the processor comprises a dial-up stage operative to establish said call connection to said terminal associated with the telephone number.

7. A terminal according to claim 1 comprising a character string translation stage configured to process the character string to provide a corresponding string in another language or alphabet.

8. A terminal according to claim 1, in which the processor comprises a geographic location stage configured to process the character string to provide information of location of the terminal.

9. Wireless telecommunications network apparatus comprising a receiver, an optical character recognition (OCR) reader, and a transmitter,

the receiver being configured to receive information of a digital photograph of an item bearing a character string from a wireless telecommunications terminal,

the OCR reader being configured to read a character string in the information of the digital photograph,

the transmitter being configured to transmit to the wireless telecommunications terminal data of or relating to the character string read by the OCR reader.

10. Wireless telecommunications network apparatus according to claim 9, comprising a directory enquiry stage configured to process the character string from the OCR reader to provide a telephone number or Internet address, the transmitter configured to transmit the data of the telephone number or Internet address.

11. Wireless telecommunications network apparatus according to claim 9, comprising an Internet search engine configured to process the character string from the OCR reader to provide a Internet address, the transmitter being configured to transmit the data of the Internet address.

12. Wireless telecommunications network apparatus according to claim 9, comprising a character string translation stage configured to process the character string to provide a corresponding character string in another language or alphabet, the transmitter being configured to transmit said corresponding character string.

13. A wireless telecommunications network apparatus according to claim 9, comprising a geographic location stage configured to process the character string to provide information of location of the terminal, wherein the transmitter is configured to transmit said information.

14. A method of using a wireless telecommunications terminal comprising a digital camera, the method comprising the steps of:

taking a digital photograph of an item bearing a character string,

receiving data of or relating to that character string, the character string having been read by optical character recognition, OCR, in information of the digital photograph.

15. A method according to claim 14, comprising the step of displaying said data of or relating to the character string.

16. A method according to claim 14, wherein the data is data of the character string that is a telephone number, the method including the step of the user indicating that a call connection to a terminal associated with the telephone number should be made, and the step of establishing said call connection to said terminal associated with the telephone number.

17. A method of operating wireless telecommunications network apparatus, the method comprising the steps of:

by radio reception receiving information of a digital photograph of an item bearing a character string from a wireless telecommunications terminal,

reading a character string in the information of the photograph using optical character recognition OCR,

by radio transmission transmitting data of or relating to the character string.

18. A system comprising a wireless telecommunications network and a mobile wireless telecommunications terminal, the terminal comprising a digital camera and a wireless telecommunications transmitter, the camera being configured to take a digital photograph of an item bearing a character string, the wireless telecommunications transmitter being configured to transmit information of the digital photograph,

the telecommunications network comprising an optical character recognition (OCR) reader configured to read a character string in the information of the photograph.

19. A system according to claim 18, wherein the network comprises a transmitter configured to transmit data of or relating to the character string from the OCR reader, and the terminal comprises a receiver configured to receive said data.

20. A system according to claim 19, in which the terminal comprises call connection circuitry, the receiver of the terminal being configured to forward to the call connection circuitry said data of or relating to the character string so as to make a call connection to a terminal associated with said data.
