Q I need to de­blur the text in an im­age. I’ve at­tached the im­age (see bot­tom left). Can you tell me what the writ­ing says? I was just help­ing out a friend who wants to know if this per­son is her class­mate from high school or not. Nancy (AP fo­rum) A Sadly, the an­swer is no. The photo you sup­plied has prob­a­bly been re­duced in size. Even if it was the orig­i­nal cam­era phone im­age at high­est res­o­lu­tion, it still would have been tricky to de­blur be­cause of the over­all sharp­ness of the im­age. It doesn’t look like it’s in fo­cus, and/or there is shake blur. The light­ing doesn’t help and nor does the re­flec­tion off the mir­ror. We are all used to amaz­ing feats of op­ti­cal res­o­lu­tion thanks to the imag­i­na­tions of TV and movie di­rec­tors, but in reality the scope for ex­tract­ing de­tails in this way are quite limited un­less you’re us­ing the right equip­ment.
