Capturing image from Webcam

Hi,
Is there any way in which Java can be used to capture
images from the webcam and save it to a predefined
image file name?
Any examples out there?
Alternatively, I could have the application written in
other languages, but still, I would need my main Java
app to launch this external app.
Thanks alot.Yes, the ExampleSave from the JavaTwain package at http://www.gnome.sk does this job :)
If you just want to see how Java Twain works with your webcam (works with a scanner too):
- java (1.2 or higher for Windows, 1.3 or higher for Mac OS X) has to be installed on your computer
- a scanner or camera has to be installed on your computer
- download the trial package from http://www.gnome.sk
- unzipp it
- go to the examples directory of the unzipped package
- in Windows: doubleclick the runExampleShow.bat
- in MacOS:
- open the Terminal window
- change the working directory to the examples
- run .sh file (type ExampleShow.sh or sh ExampleShow.sh)
This will pop up the Twain Source Selection user interface. There, all your scanners and cameras which do have a twain driver should be listed. (About 90% of scanners and cameras on the market do have a twain driver for Windows, only a few do have a twain driver for MacOS.) Select one of them. The user interface of the selected scanner (camera) will appear. Confirm the scanning (you can set the scanning parameters first). The scanned image will be displayed in a separate window. To end the application, close that window.
Running different examples, you can test scanning with hidden UI, saving the scanned image, using ADF, ...
If there is any problem, do not hesitate to inquire about it at the technical support, email: [email protected] . I am the member of the staff :)

The first error I see is that you're using the CaptureDeviceManager in an applet. If T.B.M pops in here, he can tell you why that's going to be a CF 99% of the time.
The other error I see is that your code looks absolutely nothing like any working JMF webcam capture code I've personally ever seen.
Lastly, the big one, even if you were somehow capturing video magically, you're not even trying to display it...so I'm not entirely sure why you expect to see anything with the code you just posted.

Your best bet would be starting over and using the example code from the page linked above.

Code to capture image through webcam..

hi.. im doing final year engineering.. rite now in project works n so i need a complete code in java to capture image through webcam..
can anybody pls help me in this...
thanks in advance..

can anybody suggest me on this coding n get me a full pharse of this program ready for execution....
think tis will b a easiest way to capture an image through webcam...!
INCOMPLETE PROGRAM :
```````````````````````````````````
CaptureDeviceInfo deviceInfo = CaptureDeviceManager.getDevice("vfw:Microsoft WDM Image Capture (Win32):0");
Player player = Manager.createRealizedPlayer(deviceInfo.getLocator());
player.start();
// Wait a few seconds for camera to initialise (otherwise img==null)
Thread.sleep(2000);
//take image from camera
FrameGrabbingControl frameGrabber = (FrameGrabbingControl)player.getControl("javax.media.control.FrameGrabbingControl");
Buffer buf = frameGrabber.grabFrame();
Image img1 = (new BufferToImage((VideoFormat)buf.getFormat()).createImage(buf));
then you can save image as image.jpg into buffer your computer
code:
BufferedImage buffImg = new BufferedImage(img1.getWidth(null), img1.getHeight(null), BufferedImage.TYPE_INT_RGB);
Graphics2D g2D = buffImg.createGraphics();
g2D.drawImage(img1, null, null);
g2D.setColor(Color.RED);
g2D.setFont(new Font("Verdana",Font.BOLD,16));
g2D.drawString((new Date()).toString(),10,25);
g2D.dispose();
ImageIO.write(buffImg,"jpg",new File("../Test/Webcam/Webcam" + " " + Params.Num + ".jpg"));

Unable to capture video from webcam in JMF in xlet

hi
I am unable to capture video from webcam in an Xlet. I am using Xletview to run Xlet. The method CaptureDeviceManager.getDeviceList(vidformat) returns empty array. Which videoformat should I use and why do I get empty array?
Thanks
Rajesh

MHP and OCAP only use JMF 1.0, which does not include support for capturing video. You will not be able to do this in any current MHP/OCAP imlementation that I know of.

How to Display a image from WebCam in the Forms 10.1.2.0.2!

Hi Friends!
I'm using a Forms 10.1.2.0.2 and i need to display of someway a image from webcam in some item inside the Forms!
This is possible?
I saw an explanation in http://www.orafaq.com/forum/t/89431/67467/ but it works only for a Forms 6.0!
Somebody can Help me?

As Jan mentioned, there is no way to display webcam video in Forms unless you create a Java Bean which can be incorporated into your form. As Pauli mentioned, if your webcam software is viewable via a browser, you can use WEB.SHOW_DOCUMENT to display a browser window with the content, however you will not be able to put this content in the form using the method.
A good starting place would be Google. Look for a java bean or applet which can operate a web cam.

Capturing images from camera and uploading to sharepoint library automatically.

Hello Everyone,
My requirement is to capturing images from camera and uploading to sharepoint library automatically. No manual uploading will take place.
Please suggest me.
Thanks,
Rajesh

Hi,
From your description, my understanding is that you want to capturing images from camera and uploading to sharepoint library automatically automatically upload images to SharePoint library.
You will save images in your local computer after capturing visitors’ image. You could develop a custom timer job to periodically get pictures from the local folder in your computer. Please refer to this article:
Create and Deploy Custom Timer Job Definition in SharePoint Programatically
http://www.codeproject.com/Tips/634208/Create-and-Deploy-Custom-Timer-Job-Definition-in-S
you could upload pictures to your SharePoint from the folder with C# code, please refer to this article:
How to: Upload a File to a SharePoint Site from a Local Folder
https://msdn.microsoft.com/en-us/library/office/ms454491%28v=office.14%29.aspx?f=255&MSPPError=-2147217396

Capture images from Camera directly at high resolution

Hello Users,
I want to capture images from Camera directly at high
resolution. The problem is that although I am able to capture
images from a Video Object, but the images are small because the
Video size is only 160x120. So if I am able to capture directly
from Camera, I am sure to get a higher resolution images at which
the camera is capturing.
Any help in this matter will be of great help

When capturing images from a Nikon D600, they show in Bridge, but when clicked to load into CS6,an error message says that it is the wrong type of document, even jpeg files. This is a NEW frustration.

Nikon raw files would open up in Adobe Camera Raw and so should jpegs.
If you select one in Bridge and give the command "Ctrl r" (Windows), what happens?
Also what is the version of ACR in the title bar?

Capture Image from Screen and Yosemite Mail

Composing a new mail message in Yosemite. If use the pull-down option to Capture Image from Screen and place the image in the message body (HTML), the image is not being sent with the message. A broken image icon is sent instead.
If, on the other hand, I use the paperclip to add an image file to the message body all is well. Same if I copy and paste an image into the message body.
In both those cases where it works, I also get the Markup pulldown to edit the image. In the Capture Image from Screen case where it doesn't work I also don't get the Markup pulldown menu and options.
Anyone else seeing this? Is it a known bug with Yosemite or just on my side?

I'm actually experiencing the same thing, i asked my officemate and he is also getting the same error when using capture on mac mail

Capture image from isight

What is the best way to capture images from iSight using Applescript ?

erritikamathur wrote:
What is the best way to capture images from iSight using Applescript
(1) Depending on what you want to do, you may be able to use your "Automator" application to make your scripts instead (Automator calls them "workflows".)
When you launch Automator, you can immediately select the "Photos & Images" as a starting point to see if it will meet your needs by selecting "my Computer's Camera" in the "Get content from:" choices bar there.
For more info on Automator, start with Mac 101: Automator and then launch Automator on your Mac and use its Automator > Help as needed.
(2) If you really need to use AppleScript, you need to understand that you script applications (such as iChat), not devices (like iSight.) Therefore, first decide what you want to do with your iSight. Click -> here to see a list of some applications that can operate your iSight.
Once you have decided what you want to do, launch your Mac's AppleScript Script Editor.
Next, open Script Editor's Library window to see a list of Apple apps that are scriptable. Those that can control iSight include iChat, iMovie, and iPhoto. Double-click on one of the apps of interest to see the dictionary of functions that can be scripted in that application. Reviewing the library for any app will help you determine whether the functions you want to control can be scripted in that app. If not, you need to find another app that can control that function, develop an alternate process flow that can be scripted, or look for a way to accomplish your task other than with AppleScript.
Some third party apps may also be scriptable. See the documentation or support info for particulars directly from the developers of those apps.
More help is available from a variety of sources. For instance, you can check your Mac's Help on specific applications to see if they contain info on automating them. One specific example is iChat > Help, which gives a good start on your iChat study.
Unless you already know how to use AppleScript, you may also need to do some more general study or perhaps take advantage of the Apple training series book available from the Apple Store.

Simply capture raster image from webcam or camera

Hello everybody!
First, thanks to all for all the good ideas I've read on this forum!
I would like to capture images (raster type) from an external device (webcam, camera...) to apply particular processing on them. I would not like to lose time extracting these rasters... in a way to focus on my postprocessing stage. Does anybody know the simplest way to do this? JMStudio? but how?
Thanks a lot!!!

Hi...
Could you not just use the Java Media Framework API to do an image capture from the webcam?
