1. An integrated optical scanner and cursor control device comprising:
- an image sensor used to capture instances of image data from which direction of movement of the device can be derived for controlling position of a cursor, and from which a composite image comprised of image samples from the instances of image data can be constructed;
wherein the image sensor is operable to mechanically extend from within an enclosure for use as a video camera.

Abstract
An integrated optical cursor control—image capture device and related applications. An integrated optical cursor control and scanner device includes an image sensor used to capture instances of image data from which direction of movement of the device can be derived for controlling position of a cursor. In addition, the image sensor captures instances of image data from which a composite image comprised of image samples from the instances of image data can be constructed for image scanning applications.

13. The device of claim 1 wherein the processor is operable to decode a watermark at a first spatial resolution when the image sensor is positioned for use as a video camera, and is operable to decode a watermark at a second spatial resolution when the image sensor is positioned for use as a hand held scanner.

9. An integrated optical scanner and cursor control device comprising:
-
a linear image array for capturing an image of an object as the device is moved over the object;
one or more image sensors for detecting x-y position of the device, where at least one of the image sensors is used to determine positioning of a cursor for a graphical user interface;
a light source for illuminating a surface below the device; and
a processor programmed to read a digital watermark from the image of the object that has been embedded in the object by spreading a message with a pseudo-random number to form an intermediate signal, combining the intermediate signal with a host image and applying the host image to the object. - View Dependent Claims (10, 11)
