Abstract
A method for acquiring a person's signature includes handwriting a signature by projecting movements of light. Signature information with respect to the projected light movements is concurrently acquired. The signature information is compiled to create a signature image.
Claims29
A method for acquiring a person's signature, comprising:
- concurrently acquiring signature information with respect to light movements projected in a signature motion sequence with an image-processing device;
- and
- wherein the step of concurrently acquiring signature information with respect to the projected light movements comprises (i) capturing substantially all of the projected light movements in an overexposed signature-information image at selected time intervals, and (ii) compiling the overexposed signature-information images into a signature image that shows the position of the light movements at substantially every interval of time in the signature motion sequence.
A method for capturing signature information, comprising:
- providing an image-processing device that includes (i) a camera for capturing signature information within the camera's field of view, (ii) a display for displaying signature information captured by the camera, and (iii) a computer processor communicatively connected to the camera and the display;
- as a signature is handwritten on a surface in a signature motion sequence using a light-emitting device, concurrently capturing signature information with respect to projected light using the image-processing device's camera;
- displaying the compiled signature image using the image-processing device's display;
- wherein the step of concurrently acquiring signature information with respect to the projected light comprises (i) capturing substantially all of the projected light movements in an overexposed signature-information image at selected time intervals, and (ii) compiling the overexposed signature-information images into a signature image that shows the position of the light movements at substantially every interval of time in the signature motion sequence.

- and
- displaying the compiled signature image using the image-processing device's display;
- wherein the step of concurrently acquiring signature information with respect to the projected light comprises (i) capturing substantially all of the projected light movements in an overexposed signature-information image at selected time intervals, and (ii) compiling the overexposed signature-information images into a signature image that shows the position of the light movements at substantially every interval of time in the signature motion sequence.
