Abstract
The present invention is directed toward a sensing device that reads coded data off of a surface. Interaction data is generated from the read coded data and the interaction data is processed in accordance with the image portion of the image that is extracted from an image sensor.
Claims11
A sensing device for:
- sensing coded data disposed on a surface;
- and generating interaction data based on the sensed coded data, the interaction data being indicative of interaction of the sensing device with the surface;
- the sensing device comprising:
- (a) an image sensor for capturing image information;
- (b) at least one analog to digital converter for converting the captured image information into image data;
- (c) an image processor for processing the image data to generate processed image data;
- (d) a host processor for generating the interaction data based at least partially on the processed image data;
- (e) a first framestore for storing frames of the image data;
- and
- (f) a second framestore, the sensing device being configured such that the first and second framestores respectively store alternate frames of the image data associated with alternate frames of image information sensed by the image sensor.
