Fujitsu Laboratories Ltd. said Monday it has developed technology to embed advertisers' invisible website data in television images that can be picked up by mobile phone cameras.

One use for the system would be allowing viewers to use their cellphones to download digital merchandise coupons, said the research and development arm of electronics maker Fujitsu Ltd. Advertisers would also be able to guide viewers to their websites, it said.

Fujitsu is aiming to commercialize the technology by the next business year.
