Abstract

A mobile telephone is provided, that is easy to manipulate manually and can perform electric authentication and input a character by providing an additional value to a conventional mobile telephone.

A mobile telephone 1 is disposed which communicates information, and as motion detecting means which detects all or some of movement of the main body of the mobile telephone 1, a CCD 40, a camera 50 and the like are disposed.

Claims

1. (Amended) a portable terminal, comprising:

a portable terminal main body which communicates information; and

motion detecting means which detects all or some of movement of said portable terminal main body during a writing action made with said portable terminal main body, said motion detecting means comprising a CCD camera,

and characterized in that said CCD camera captures an image other than said portable terminal main body and a part of said portable terminal main body,

and that said motion detecting means detects said movement based on thus captured image.

2. (Amended) The portable terminal of claim 1, wherein said motion detecting means detects said movement based on a motion vector of the image detected by said CCD camera.

3. (Amended) The portable terminal of claim 1 or 2, comprising recognizing means which recognizes, as data representing a character or graphic form, all or some of movement of said portable terminal main body detected by said motion detecting means.

4. (Amended) The portable terminal of any one of claims 1 through 3, wherein said part of said portable terminal main body is an antenna portion of said portable terminal.

5. (Amended) The portable terminal of any one of claims 1 through 4, comprising a writing portion which is disposed to said part of said portable terminal main body and which writes a character or graphic form.

6. (Amended) The portable terminal of any one of claims 1 through 5, wherein said portable terminal is all or some of a telephone, a remote controller and an information processing apparatus.

7. (Amended) A signature authentication method characterized in using a character or character data obtained through all or some of movement of said portable terminal main body of said portable terminal of claim 1, as a signature for authentication.

8. (Amended) A program recording medium of making a computer function as all or some of motion detecting means which detects all or some of movement of said portable terminal main body of said portable terminal of claim 3 and all or some of recognizing means which recognizes, as data representing a character or graphic form, all or some of movement of said portable terminal main body.

9. (Amended) A program which makes a computer function as all or some of motion detecting means which detects all or some of movement of said portable terminal main body of said portable terminal of claim 3 and all or some of recognizing means which recognizes, as data representing a character or graphic form, all or some of movement of said portable terminal main body.
