Abstract

Electronic device: including an image sensor; a screen for displaying a view captured by the image sensor; a motion detector for detecting a motion of the electronic device; and a variable being associated with a position on the screen and a specific selecting manipulation; and the electronic device being arranged: to change a value of the variable in every moment triggered by the selecting manipulation so as to compensate a motion of the electronic device by utilizing the motion detector; and to define an operation area associated with an operation of the electronic device based on the value of the variable. The above-described electronic device enables a user to interact with information of the real world intuitively.

Claims

1. An electronic device comprising:

an image sensor;

a screen for displaying a view captured by the image sensor;

a motion detection means for detecting a motion of the electronic device;

a variable being associated with a position on the screen and a predetermined selecting manipulation; and

,

an OCR means

and the electronic device being arranged;

to change a value of the variable in every moment triggered by the selecting manipulation so as to compensate a motion of the electronic device by utilizing the motion detection means; and

to define an operation area associated with an operation of the electronic device based on the value of the variable;

where said operation comprising taking an image date by capturing a view of the operation area by the image sensor, extracting a character information from the image data as a text data by the OCR means, and storing the text data in a shared memory space which is used to transfer data between applications or within an application.

2. An electronic device according to claim 1, comprising a plurality of variables, each of them being associated with a own position on the screen and a own selecting manipulation, and wherein the electronic device being arranged to define said operation area based on values of said plurality of variables.

3. An electronic device according to claim 1 being arranged to indicate on the screen a position relating to the value of the variable.

4. An electronic device according claim 1, wherein an initial value of the variable relating to a center position of the screen.

5. An electronic device according to claim 1 being arranged to define a screen area based on the value of the variable, and to indicate the screen area on the screen.

15. An electronic device according to claim 1, wherein said motion detection means comprising an accelerometer for measuring inclination of the electronic device, where the inclination is used for correcting the image data to improve an accuracy of OCR processing.

6-14. -14. (canceled)

16. A mobile phone comprising

a camera for taking a picture;

a user interface having at least one key;

a screen for displaying a view captured by the camera;

motion detection means for detecting a motion of the mobile phone; and

a processor having an OCR function;

where the processor further comprising a first and a second variables associated with a position on the screen; and

the processor being arranged;

in response to press the key, to start changing the values of the first variable so as to compensate a motion of the mobile phone which is detected by the motion detection means and indicating a rectangle area on the screen which is determined by positions corresponding to the current values of the first and the second variables as opposite corners;

in response to release the key which corresponds to the pressing of the key, to start changing the values of the second variable so as to compensate a motion of the mobile phone which is detected by the motion detection means and to continue indicating the rectangle area on the screen which is determined by positions corresponding to the current values of the first and the second variables as opposite corners;

in response a further operation of the user interface, to take an image date by capturing a view of the operation area by the camera, to extract a character information from the image data as a text data by an OCR processing and to store the text data in a memory space so that the text data can be pasted in an application program of the mobile phone.

17. A computer program for an electronic device comprising an image sensor, a screen for displaying a view captured by the image sensor, a motion detection means for detecting a motion of the electronic device, and a processor;

the computer program comprising a variable associated with a position on the screen and a predetermined selecting manipulation;

and the computer program being arranged to instruct the processor to perform;

changing a value of the variable in every moment triggered by the selecting manipulation so as to compensate a motion of the electronic device by utilizing the motion detection means; and

upon finishing the selecting manipulation, defining an operation area based on the value of the variable, taking an image date by capturing a view of the operation area by the image sensor, extracting a character information from the image data as a text data by an OCR processing, and storing the text data in a shared memory space which is used to transfer data between applications or within an application.

18. A computer program according to claim 17, comprising a plurality of variables, each of them being associated with a own position on the screen and a own selecting manipulation, and being arranged to instruct the processor to define said operation area based on values of said plurality of variables.

19. A computer program according to claim 17, comprising:

a means for instructing the processor to indicate on the screen a position relating to the value of the variable; and

a means for instructing the processor to define a screen area based on the value of the variable, and to indicate on the screen the screen area.

20. A computer program according to claim 17 being arranged to instruct the processor to show an error message on the screen when the motion detection means detecting a motion being larger than a threshold.

21. A method for copying undigitized character information as a digitized text data for an electronic device comprising an image sensor, a screen for displaying a view captured by the image sensor, a motion detection means for detecting a motion of the electronic device and a variable being associated with a position on the screen and a predetermined selecting manipulation;

where the method comprising the steps of;

changing a value of the variable in every moment triggered by the selecting manipulation so as to compensate a motion of the electronic device by utilizing the motion detection means;

defining an operation area based on the value of the variable; and

,

taking an image date by capturing a view of the operation area by the image sensor, extracting a character information from the image data as a text data by an OCR processing, and storing the text data in a shared memory space which is used to transfer data between applications or within an application.
