Pocket PC Forum / End Users / Wireless / May 2004Using a Camera with PPC for Photos of Documents
I am having a hard time finding a document scanner to work with my iPaq 4155. Has anyone used a camera to take document photos? If so, what camera did you use and how did you overcome memory storage issues? The current crop of PPC based cameras are nothing but low-res toys, and will not be able to do what you need. Look for a REAL digital camera, 5MP or larger. > I am having a hard time finding a document scanner to work with my iPaq > 4155. Has anyone used a camera to take document photos?

However, I suspect that some of the 1 megapixel cameras can probably do pretty well for tasks like grabbing an image of a document. In any case, I do not think that Betty limited her question to just CF/SD cameras or scanners. You definitely do not need a 5 megapixel camera just to photograph a document. In fact, even the lower-end 1 or 2 megapixel cameras do a quite decent job of that kind of task. Betty: Hop down to your nearest retail store with CF/SD cameras and ask if you can test it in-store to see if it meets your needs. If not, take a look at some of the reasonably priced 2 megapixel cameras with a storage card type that is compatible with your PPC (SD or CF). You can reduce file sizes by choosing a lower resolution (say 1 megapixel) and setting the camera to take high contrast grayscale images.

You do if the doc is 8 x 10 or larger and has 10pt (or less) text on it....and you don't wanna guess at that word you can't quite decipher on your screen *later*. Far better to have more res. than you need, than the other way 'round. > Betty: Hop down to your nearest retail store with CF/SD cameras and ask if > you can test it in-store to see if it meets your needs.

You do not need a high resolution digital camera to take readable photos of a printed page. In fact, one of the problems in places like Japan where camera phones have been available longer than in the US, there is the problem of people taking photos of magazine pages instead of buying the magazine. To prove the point, I took a quick snapshot of a magazine page under a pretty awful lighting condition (single off center light in my workroom with the magazine on my chair seat) using a low-priced 2 megapixel camera with the flash turned off. You can find the image at... http://mobileviews.com/temp/paperpage.jpg If you use Internet Explorer, it may resize it to fit the page (make it smaller). So, place your cursor at the lower right hand corner of the image until you see a box with four arrows pointing inwards. Click on this little box to see the image at full resolution. You will find the text quite readable. > > I disagree (partly at least). > > [quoted text clipped - 41 lines] > > > camera > > > > did you use and how did you overcome memory storage issues? OK, point conceded. I must admit, the last time I tried this with a <2MP camera was a while ago, and the results were pretty bad, hence my bias against them. I wonder, are the optics of the PPC based cameras up to this task? > Sorry, you are still incorrect. You do not need a high resolution digital > camera to take readable photos of a printed page.

It really depends on the CF/SDIO camera used. I have not tried the newer 1 megapixel units. But, I tested a bunch of the 640x480 (and one 800x600) units and found a lot of variance in quality. You can find a bunch of comparison photos I took with these CF cameras (plus some camera phones) at: http://mobileviews.com/merlin/reviews/cfcameras.htm ....todd > OK, point conceded. > [quoted text clipped - 84 lines] > > > > > camera > > > > > > did you use and how did you overcome memory storage issues? Hi Todd ! Long time ! I would have never thought what you said about taking the low res. photo of that magazine page would work and be readable until you posted the photo on your URL (http://mobileviews.com/temp/paperpage.jpg) my "old opinion" was that you would need a 3 MP or higher has just been readjusted by that .jpg you posted. Thanks for the update ! I decided to take it one step farther and print part of the page using only medium resolution on my HP Deskjet 970 Cse and ran it thru my old HP ScanJet 6300C using just the basic OCR software provided and was nicely surprised that out of all that was scanned, only two errors. I would say that is pretty darn good for a shot with low light/no flash ! SignatureTedd Riggs PDA Square Content Developer www.pdasquare.com Redmond, WA >> Sorry, you are still incorrect.

Just go the new HP r707 camera which I am very impressed with. Using 5mp images in the document mode you can cycle through images really quickly. Plus they both use SD card technology which makes life easier. cheers, James > Hi Todd ! > Long time !

Appreciate the help. :) Betty > Sorry, you are still incorrect. You do not need a high resolution digital > camera to take readable photos of a printed page.
