Why do Google Street View signs blur

Why is Google blurring the name on this street sign?

I was looking for a specific road sign on StreetView in the UK but when I got to the location I saw this:

Why did Google blur the street name but only part of the street name?

Other views haven't blurred the name, but in those the mark is either further away or more sharp-edged.

I can't be for privacy reasons - after all, it's the Street View point of knowing where you are.


Google Maps: Street View: Privacy and Security (English version)

Individuals and marks are out of focus

We developed an innovative technology for blurring faces and license plates that is applied to all Street View images. This means that if one of our images has an identifiable face (e.g. that of a passerby on the sidewalk) or an identifiable license plate, our technology will automatically blur it, which means the person or vehicle cannot be identified. If our algorithms missed something, you can easily let us know.

I bet it's a false positive for a license plate. You can always use the "Report a Problem" link at the bottom of the page.

(For what it's worth, it's blurry to me here in the US)

Via the Google Maps support forum:

All faces, license plates, etc. are blurred to protect privacy. Sometimes wrong pictures like the detected character are captured and blurred. This is an automated process and is irreversible.
