Camera system comprising color display and processor for decoding data blocks in printed coding pattern

摘要

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; 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; and performing an action in the handheld digital camera device based on the decoded coding pattern. The decoding includes the steps of: identifying a data block in the imaged coding pattern; decoding a control block to determine the size of data to be extracted from a data area; and decoding the coding pattern contained in ae data area of the data block.

1. A camera system comprising:
a coded media displaying a coded pattern, said coded pattern including a data block, wherein the data block contains a data area containing encoded information regarding a size of data encoded in the data area; and a portable camera device comprising: an image sensor configured to capture an image of the coded pattern and generate data representing a digital representation of said image; a color display; and an integral processor configured for:
controlling operation of the image sensor and the color display;collecting the data representing the digital representation of said image directly from the image sensor;processing the data representing the digital representation of said image to decode the coded pattern;generating decoded information decoded from the coded pattern; andperforming an action in said portable camera device based on the decoded information, wherein said processing includes:
identifying the data block in the image of the coded pattern;determining the size of data encoded in the data area; anddecoding the data area of the data block; wherein said portable camera device further comprises a second image sensor; and wherein the second image sensor is configured for capturing an image to display on the color display.
