CAMERA SYSTEM WITH COLOR DISPLAY AND PROCESSOR FOR REED-SOLOMON DECODING
First Claim
1. A camera system comprising:
- a substrate having a coding pattern printed thereon, said coding pattern employing Reed-Solomon encoding, wherein a data block of the coding pattern comprises;
a plurality of target structures and a data area containing encoded information, the extent of the data area being defined by the target structures; and
a handheld digital camera device comprising;
a digital camera unit comprising a first image sensor for capturing images and a color display for displaying captured images to a user; and
an integral processor configured for;
controlling operation of the first image sensor and color display;
decoding an imaged coding pattern printed on the substrate; and
performing an action in said handheld digital camera device based on the decoded coding pattern, wherein said decoding comprises the steps of;
detecting the target structures defining the extent of the data area;
determining the data area using the detected target structures; and
Reed-Solomon decoding the coding pattern contained in the determined data area.

Abstract
A camera system including: a substrate having a coding pattern printed thereon and
a handheld digital camera device. The camera device includes: a digital camera unit having a first image sensor for capturing images and a color display for displaying captured images to a user; an integral processor configured for: controlling operation of the first image sensor and color display; decoding an imaged coding pattern printed on a substrate, the printed coding pattern employing Reed-Solomon encoding; and performing an action in the handheld digital camera device based on the decoded coding pattern. The decoding includes the steps of: detecting target structures defining the extent of the data area; determining the data area using the detected target structures; and Reed-Solomon decoding the coding pattern contained in the determined data area.
