Camera Models

Post by allranger » 19 Oct 2009, 12:39

Hello,
I am going to have my book scanner frame completed this week so I'm moving to the next logical set: looking for cameras and software.
I was thinking that cameras that could be controled from the computer over use would be useful. Has anybody explored that option?

EDIT: I guess I am asking what options on a camera I should be looking for. I am not real sure even what ot ask for when looking at the different camera models. In my mind it would be cool if the data showed up on the screen the same way it does on the atiz book scanner. I see that some people have been using an tv tunner card option. Can any one comment on how well that works?

Hi

I have looked into this option so far unsuccessfully. Atiz uses the Canon SDK which is very limits the models you can use to mostly the last generation on Canon products.

The Canon SDK supports these models and its not Supported in Vista .Canon seems to removing SDK support for there point and shoot cameras.
These are some cameras that the sdk supports now.
Canon Powershot G9, Canon Powershot G7, Canon Powershot A620, Canon Powershot S5 IS
Canon Powershot S80 Canon Powershot A640 Canon Powershot S3 IS ,Canon Powershot SX 100 IS


Other camera manufacters do produce there own SDK (Kodak, Nikon etc) but I havent looked into this.

THe other idea I looked at is using Windows Image Acquisition (WIA) but it seems not all hardware supports this .

Another one of interest was Tcamremote for delphi and ocx. It is shareware

I do think it would be easier to have software that grabs the image from the digital camera to the computer , does a little postprocessing and combines them into page order.

Linux options

Post by Hasher » 20 Oct 2009, 08:09

Looking around today


and found this :

http://libptp.sourceforge.net/
libptp2 is a library used to communicate with PTP devices like still imaging cameras or MP3 players (KODAK mc3). You can download files or tweak camera properties using ptpcam program boundled with libptp2.

and

http://capture.sourceforge.net/
Capture is a tool for periodic image capturing with digital Canon cameras. It is licensed under GPL and it was developed for Linux. Although there were some attempts to port the underlying libptp to MacOS, i do not know if this effort was successful.

The program is command-line oriented: the commands can be specified as command line parameters (useful for scripting) or can be entered in an interactive mode. It can take a shot, set various properties of the camera, open a viewfinder window (works like a webcam) and save viewfinder images.


But then I found this: http://www.gphoto.org/ and WOW
gPhoto2 is a free, redistributable, ready to use set of digital camera software applications for Unix-like systems, written by a whole team of dedicated volunteers around the world. It supports more than 1100 cameras

Hey guys, we've discussed Gphoto2 before, I think. Actually we've discussed cameras a few times, too. It might be time for a FAQ. In the meantime, check out these threads:

http://diybookscanner.org/forum/viewtopic.php?f=1&t=100
http://diybookscanner.org/forum/viewtopic.php?f=1&t=117
http://diybookscanner.org/forum/viewtopic.php?f=1&t=38

One idea that I've had for a while (but don't currently have the time or interest to work on) would be to make an Ubuntu liveCD that would convert any computer into a 2 camera scanning station.

I'll check out gPhoto2. It looks pretty interesting. I guess I will be going the Linux route for picture capture is this is the case.
I browsed down the the list and it looks like the Canon PowerShot G10 is fully supported. I was looking at the camera already because it has a high Megapixel so that is good.
I think a FAQ would be a good idea. Part of the problem is that I am even sure of the terminology that I need to state the questions in. For example, I just found out the PTP means picture transfer protocal and it is probably something that I want. If I can get two of these models and setup gPhoto so that it will cature both of them then I will be happy.

Hello Ranger,
It is a very difficult to select a camera model that fits our needs and the feature you demanding is rarely found in any camera. But Canon cameras model G7, 9 supports this feature, don't worry soon new camera with that feature will be available in market. And this cameras provides Software development kit which lets u use the cameras as a scanner and that's also with a really good clarity.If there's any more question than u can post me a reply.

For anyone that didn't catch it, gphoto has a list of cameras that operate remotely http://www.gphoto.org/doc/remote/ and that links to Canon's most recent list of cameras supported by their SDK http://www.usa.canon.com/consumer/contr ... 74&id=3464

Apparently Canon isn't going to support any of the Powershot line with their SDK in the future which is an unfortunate development. They want you to buy their more expensive models to get that feature.

What I didn't see clearly spelled out, but I assume is that any camera that operates remotely is able to do so while connected with its AC adapter. I inferred that due to one of the gphoto FAQ entries about bugs in the Canon G1, G2 and another camera that don't work from AC power. It would be nice to be sure though what cameras operate off AC power as well. I'll try to see if I can find out.

I'd also like to see if anyone has tested the 8MP webcams mentioned in one of the threads. The person that said they would try it never reported back, so that may be good or bad. My primary purpose is for OCR, so I'm hoping it would be good enough for that.

Finally,

I think that's something I could handle. What kind of sofware would people want on it? gphoto and Scantailor for sure. GIMP comes by default for more general image processing. I could put tesseract on their for OCR, since it works reasonably well on one column text.
