Look at me! Windows Image Acquisition

re: Look at me! Windows Image Acquisition

Ben — Fri, 23 Feb 2007 16:22:17 GMT

Great sample. I'm working on the Flcikr integration.

Does anyone know how I can open the camera device's built-in configuration properties dialog through code?

The select device dialog doesn't give me access to the manaufacturer's own properties window which I thought it would.

Interestingly, using Skype, the "video settings" option within Skype itself does open the manaufacturer's own properties dialog, so it must be possible.

When I use this sample the device settings are defaulted. Any ideas how I can access these settings and save them. I've searched everywhere and I'm stumped.

I want to set the camera to its "Outdoor" mode, as the result is far too bright.

Hi,

Neat program. However I wasn't able to work it. the WIA has been installed however I can't see no image in the image box.( I did click on configure) If you can help me it will be great!

Hi, i found your article to be excellent, but i have one simple question.

I want to select a webcam and save it in my database so when i enter again to the project i can just look for it at the DB.

i thought that would be possible by just saving the device id in the DB and then just setting the DeviceID to that value when i enter the project again but it didnt work.

Could you help me there?

I use Windows XP x64, and can't get the dll registered when copied to the system32 folder.

I get the error:

LoadLibrary("WIAAut.DLL") failed - The specified module could not be found.

If I put it in another directory, I get it registered, but I get runtime errors when using it in Visual Studio 2005.

Runtime error:

Retrieving the COM class factory for component with CLSID {850D1D11-70F3-4BE5-9A11-77AA6B2BB201} failed due to the following error: 80040154.

The runtime error indicates that the class I'm trying to use, WIA.CommonDialogClass is not registered.

Is there an alternative dll or method for x64 systems ?

Hi! Great example, got me started pretty quick! There's this problem that if I just use the Item item = device.ExecuteCommand(CommandID.wiaCommandTakePicture); command the picture is always all black.

I've been thinking that the webcam should be "turned on" somehow first. F.ex. if I open the ShowAcquireImage -dialog, the image is first all black and after a while the video preview starts to show. Then I can take pictures I want. But the problem is that I need to take pictures automatically without user interaction but they are all black. Any suggestions?

not by me. have spent several hours with the wia automation layer which is just the camera and scanner wizard.wiacommandtakepicture always returns black screen item. if turn webcam "on" say by videopreview on form wether paused or not causes system hangup. only way I found to get picture is by brute force of copyfromscreen of videopreview to an image file.

but GUI all the same appears (((how to scan without GUI?

re: Look at me! Windows Image Acquisition

Coding4Fun — Mon, 08 Dec 2008 23:41:43 GMT

@Dima check out the second "Taking a Picture". it shows you how to get a picture just from pure API.

From what you have, just do IF.SaveFile

I'd also not name my var IF as it is too close to "if". Remember to abuse intellisense to make your code readable.

using VS 2008/VB, converted the VB 6 to the current version. The program runs and the camera takes picture(s), but shortly after I get a null reference error. Turns out that and cannot make your program the following line:

Dim item As Item = device.ExecuteCommand(CommandID.wiaCommandTakePicture)

returns "nothing" , so later when I reference item in line

CType(item.Transfer(format), WIA.ImageFile)

blows up.

searching for days for solution no luck.

Q: is this a vista issue?

I have a simple html vbscript program, which has no problem triggering my Nikon D60, and loading the picture on the screen, but I cannot repeat the same with the VB program.

@ "x64 user":

If you're trying to do this in XP x64, the problem is that c:\windows\system32 is, for some reason, not in the search path of regsvr32.

Using Process Explorer from Sysinternals, you can log the operations regsvr32 does. Filter them by process "is" (regsvr32.exe), result "contains" "not found", and path "contains" "wiaaut". If you're having the problem I did, it means regsvr32 was looking for the file everywhere except system32. Not only that, if you try to type in the full path it doesn't help. I moved it to windows\system and registration succeeded.

By the way, the idea to use Process Explorer is from http://www.cryer.co.uk/brian/windows/trbl_xp_regsvr_fld_module_not_found.htm

Nice article :)

I am making a Lab Complaint Management in C# and would like the webcams placed in every lab to record the videos and save in a database or at some place.

The people using software, to whom given the rights should be able to see the live web cams of any lab, all the labs are networked to each other.

So two features

1) Able to checkout live cams of any lab

2) Record the video at some place

This need to be done in C# - Can anyone help? Am a newbie - Thanks a lot friends.

To store an image in a database (most wouldn't recommend this), use a BLOB data type. I'd suggest storing a file path instead to the image.

Are there any solution where one can capture images from a digital Camera to an image control in real time (not a web cam)?

I have been searching the web for days trying to locate such hardware software solution to no avail. I found plenty of references for web cams though.

re: Look at me! Windows Image Acquisition

Coding4Fun — Fri, 04 Dec 2009 16:59:36 GMT

@Oea Tek, part of the problem here is you need API references into the camera to do this. It isn't as straight forward as you think. I've been wanting to do this to my Canon T1i. Each camera's API may be slightly different and depending on it, the camera may not even have one. I know Canon mid and high range cameras do, as does Nikon.

This is something I've been thinking about building an SDK for but it is far harder and has more moving parts than one may think. Canon, while it has the API, has some restrictions on how you can distribute and how you can even get a hold of their API. I tried twice and haven't heard back.

@Ambeen, I removed the link since I did a quick glance at it and the DLL that does the actual webcam processing worries me where you got it from and how you're distributing it. I'll be more than happy to post a link to your blog once I feel a bit more comfortable about where that webcam code came from. Please hit the "email us" link so we can clear this up.
