Your digital camera is now a portable scanner
What would you do with an 8.0 megapixel camera? It’s a valid question considering that even just 3.2 megapixels can already give you decent archive-quality photos.
Well, megapixel-rich cameras like the Olympus Mju DIGITAL 800 (reviewed in our upcoming issue of m|ph) have one potential killer application: Document capture mode. It allows you to take a picture of a full page of a document with sufficient detail to actually make it readable when viewed on a monitor or printed out later on.
Truth be told, even a 3.2 megapixel camera does a fair job of capturing a regular 8.5×11″ document, provided that it contains font sizes of 12 and up. Font size 10 is tolerable. But at font size 9, the punctuations start becoming difficult to make out. And at font size 7, you start having to guess what some of the characters are.
But with a large enough resolution and a fast shutter speed, capturing even the fine print on legal documents should be a breeze. Students can then use their cameras to reproduce pages from books, or even to quickly copy their classmates’ notes.
It would be great to have a camera-phone with an 8-megapixel “document scanner” mode, but that’s probably still a couple of years away.




Oh my gulay. I’d love to have one of these during a heritage research tour — when you run across a goldmine of archival material, mostly handwritten and crumbling away, that’s either too delicate to transport, let alone lay face down on a scanner’s bed. And who’d have a scanner in their backpack when exploring little sleepy towns to document their heritage anyway?
In my line of work, I encounter materials (usually paper, sometimes even fabric) that are in such terrible shape that you wouldn’t dream of subjecting them to too much handling. Something like this, with its Document Capture mode, would be perfect to use. You don’t handle the material, and you have a very hi-resolution image that you get far quicker than with a scanner (I’m assuming!). Paper labels at the backs of old, fragile paintings, handwritten church records, building plans, old photographs and journals… the possibilities! Agh!
