Computer input device
First Claim
1. An input device for generating data representative of handwritten strokes and for capturing scenes, the input device comprising:
- an image capturing unit for capturing handwriting image data representative of handwriting strokes based on movement of the input device and for capturing scene image data, the image capturing unit having a first focal length while in the handwriting mode and a second focal length while in a scene capture mode, the second focal length being different than the first focal length;
a processor for generating handwriting data based on the captured handwriting image data; and
a memory for storing the handwriting data and the scene image data.

Abstract
A dual-mode input device is provided for capturing handwritten electronic ink while in a handwriting mode and for capturing scenes while in a scene capture mode. The input device includes an image capture system having a first focal length while in the handwriting mode and having a second focal length while in the scene capture mode. The input device may include a digital pen and may have a pen cap that acts as an adaptor to change the image capture system focal length between the first focal length and the second focal length. The input device may include a variable focal length mechanism for providing variable focal lengths while in the scene capture mode.

16. A method for capturing image data via a single input device, the method comprising:
-
placing the input device in a handwriting mode;
while in the handwriting mode, capturing first image data representative of handwritten strokes;
placing the input device in a scene capture mode;
while in the scene capture mode, capturing second image data including scenes. - View Dependent Claims (17, 18, 19)

20. A digital pen for generating data representative of handwritten strokes and for capturing scenes, the digital pen comprising:
-
a camera system capturing an image of an area of an object over which the digital pen is positioned while in a handwriting mode and generating captured image data, the camera system having a first focal length while in the handwriting mode and a second focal length while in a scene capture mode, the second focal length being larger than the first focal length; and
a processor for processing the captured image data;
a memory for storing data representative of handwritten strokes based on first image data of the captured image data, the first image data including image data captured while in the handwriting mode, and for storing scenes captured while in the scene capture mode; and
a pen cap for changing the camera system from the first focal length to the second focal length.
