Japanese photo translation app android?

Can anyone recommend a good android photo translation app. On my next trip i will be out in the suburbs a lot and don't expect to find much english. I will be using a galaxy s3 and need an app that will be good at translation place names etc.

There's this :

I have no idea if it's any good though. Place names are particularly tricky as even native speakers sometimes are unsure how to read a particular place name.
