Add Street View to the list of concerns the European Union is raising about how Google Inc. treats consumer privacy.

European regulators have warned the search giant that they don't believe it is doing enough to let people know when its cameras are rolling through their neighborhoods taking pictures to post online on its Street View section of Google Maps.

The EU also wants Google to reduce the amount of time a given photo is up - from the current period of one year to six months.

Alex Turk, the head of EU data-protection agencies, sent a letter to Google Feb. 11 telling the company that it not only needs to give advance notice of where its camera van is traveling on its Web site, but must also post notices in the local or national press.

The letter tells Google to avoid posting pictures "of a sensitive nature and those containing intimate details not normally observable by a passer-by."

It further says that Google could do more than it already does to blur faces and car license plates caught in its Street View shots.

Google said it believes it takes sufficient care to protect privacy and warn of where it is shooting, and that its need to retain images for a year are legitimate and justified.

News of the EU letter came in the same week that three top Google executives were convicted in Italy because of a video posted on a precursor to YouTube of a boy being bullied.

The company was also notified last week that the EU is looking into antitrust claims made by three European companies, two of which have ties to its competitor Microsoft Corp.
