Camera system with color display and processor for reed-solomon decoding

1. A portable 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 a substrate, said printed coding pattern employing Reed-Solomon encoding; and

performing an action in said handheld digital camera device based on the decoded coding pattern,

wherein said decoding comprises the steps of:

detecting target structures defining an extent of a data area;

determining the data area using the detected target structures; and

Reed-Solomon decoding the coding pattern contained in the determined data area,

wherein the action performed in said device is an image-warping effect.

2. The portable digital camera device of claim 1 , further comprising a second image sensor.

3. The portable digital camera device of claim 2 , wherein the second image sensor is configured for imaging the coding pattern.

4. The portable digital camera device of claim 2 , wherein said first and second image sensors are configured for capturing stereoscopic digital images.

5. The portable digital camera device of claim 1 , wherein said processor is configured to perform said Reed-Solomon decoding in less than 0.32 seconds.

6. The portable digital camera device of claim 1 , wherein said decoding comprises the further step of:

determining one or more control blocks in the data area, said control blocks containing encoded information required for subsequent Reed-Solomon decoding.

7. The portable digital camera device of claim 6 , wherein each control block contains encoded information regarding the size of data to be extracted from the data area.

8. The portable digital camera device of claim 1 , wherein said Reed-Solomon decoding corrects for one or more errors in the imaged coding pattern.
