Abstract

An electronic device includes a camera that is configured to generate a visual data signal that corresponds to dynamically captured graphic content that includes an image and a pointer that is operable to communicate a selection characteristic of the image. A signal processor receives the visual data signal and is operable to identify a portion of the image in the dynamically captured graphic content responsive to the selection characteristic communicated by the pointer.

Claims

1. An electronic device, comprising:

a camera that is configured to generate a visual data signal that corresponds to dynamically captured graphic content that includes an image and a pointer that is operable to communicate a selection characteristic of the image; and

a signal processor that receives the visual data signal and is operable to identify a portion of the image in the dynamically captured graphic content responsive to the selection characteristic communicated by the pointer.

2. The electronic device of claim 1,

wherein the pointer comprises a user digit, and

wherein the selection characteristic comprises an underline characteristic that is operable to identify the portion of the image by an underlining motion that is dynamically captured.

3. The electronic device of claim 1,

wherein the pointer comprises two user digits,

wherein the selection characteristic comprises a border characteristic that defines starting point that corresponds to a first one of the two user digits and an ending point that corresponds to a second one of the two user digits, and

wherein the portion of the image is between the starting point and ending point.

4. The electronic device of claim 3, wherein the starting point and the ending point are horizontally spaced apart to define the portion of the image as a plurality of words in a line of text data.

5. The electronic device of claim 3, wherein the starting point and the ending point are spaced apart to define the portion of the image as a plurality of lines of text data.

6. The electronic device of claim 1,

wherein the pointer comprises two user digits,

wherein the selection characteristic comprises an aspect ratio characteristic that defines a substantially rectangular portion of text data by diagonally opposite corners thereof.

7. The electronic device of claim 1, wherein the further comprising a transceiver that is configured to send the portion of the image to a processor that is configured to analyze the portion of the image.

8. The electronic device of claim 7,

wherein the processor comprises a processor that is external to the electronic device and is further configured to identify a source corresponding to the image responsive to analyzing the portion of the image, and

wherein the transceiver is further configured to receive source data corresponding to the image responsive to the processor identifying the source.

9. The electronic device of claim 8, wherein the source data comprises a source name, a unique source identifier, and/or text data that corresponds to the portion of the image.

10. The electronic device of claim 7, wherein the processor is configured to analyze the portion of the image by recognizing at least one pattern in the portion of the image, the at least one pattern including a text data appearance, a text data format and/or at least one set including multiple words of text.

11. The electronic device of claim 1, wherein the visual data signal comprises a video signal that includes multiple frames per second of the image and the pointer, the device further comprising a processor that is configured to analyze the portion of the image and to identify a source corresponding to the image responsive thereto.

12. The electronic device of claim 1, wherein the electronic device comprises a mobile communication terminal.

13. A method of capturing text data, the method comprising:

identifying a portion of an image by generating a video signal of at least one section of the image and a user directed pointer that is operable to identify the portion of the image.

14. The method of claim 13, wherein the user directed pointer includes a user digit, wherein identifying the portion of the image further comprises:

receiving video data of the image and the user digit that identifies the portion of the image; and

sending the portion of the image to a processor that is operable to analyze the portion of the image.

15. The method of claim 14,

wherein the processor includes an external processor, and

wherein sending the portion of the image comprises streaming video data to the external processor, the streaming video data including the portion of the image that is identified by the user digit in the video data.

16. The method of claim 13,

wherein the image includes alphanumeric text,

wherein the user directed pointer includes a user digit, and

wherein identifying the portion of the image comprises generating video data corresponding to user digit gestures that identify a portion of the alphanumeric text.

17. The method of claim 16, further comprising:

analyzing the portion of the alphanumeric text to identify a source of the alphanumeric text; and

generating source data corresponding to the source.

18. The method of claim 17, further comprising receiving data corresponding to the image responsive to analyzing the portion of the image that is identified by the user digit.

19. The method of claim 17, wherein the source data includes a source name, a unique source identifier, and/or text data that corresponds to the portion of the alphanumeric text.

20. The method of claim 13, wherein identifying the portion of the image comprises capturing a marking-up function in the generated video signal via user digit gestures relative to the image.
