Windows XP "Capture Pictures from Video"

Not exactly a hardware question; perhaps you want to move this to Multimedia Applications?

Hi Callandor,

I agree with you and I apologise for posting in the incorrect place. I am happy for this to be moved.

Ok, I've notified Community Support.

In the meantime, in most programs if you simply right-click on the thumbnail, "delete" will usually be one of the choices.

Netminder: Thank you very much

Watzman: I have tried this and the option is not available. Selecting the thumbnails and pressing the Del key on the keyboard does not work either.

Any other ideas?

Have you searched your profile? Go to My Documents and see if you have a My Pictures or other subfolder, where the captured pictures can be.

Crissand:

Yes, I have done this and found nothing. Thanks for the suggestion anyway.

Jon

Is there a posibility that the webcam to have its own memory? Maybe the captured images are there and not in the computer's harddisk.

The are probably stored in "my pictures".

But here's a way to find out:  Take a picture (still picture).  Then immediately do:

Start / Find (or search) and look for *.JPG (any JPEG file (assuming that it stores them as a JPEG)), and use the "time" qualifier to find only files created in the past 24 hours.  The file found should be the picture that you just saved (of course, if you know the actual filename, that's even better).  Once the image is found, you can see where it is, and it's highly likely that all of your images will be in the same place.

Crissand: I had not thought of that, but I have checked and this particular webcam does not have any memory.

Watzman: A very good idea and I tried it. I took a picture of a battery and then searched for all GIFs, JPEGs and PNGs created within the last day. None of them were my pic of my battery.

So thanks very much both of you, but still no solution!

Jon

That's surprising.  Either it's being stored in a format other than JPEG (very uncommon these days), or perhaps it is indeed in the camera and not on the computer.

Which exact extensions did you search for?  JPG is the actual extension for JPEGs.

Callandor: I did four seperate searches for *.jpg, *.JPG, *.jpeg and *.JPEG.

Thanks,

Jon

What webcam do you have, and how is connected to computer?

The Webcam is a Logitech Quickcam Express, connected via USB.

Thanks,

Jon

In the folder %WINDIR%\twain_32\DEVICE must be one or some image files. My camera creates a file called preview.bmp there.

DEVICE must be replaced with the name of the device, explore the folder %WINDIR%\twain_32\ to see.

Hi,

In the folder C:\WINDOWS\twain_32\QuickCam the following files appear AFTER I have taken some previews that appear in the "Capture Pictures from Video" box:

click.wav
HPortal.dll
HVideoS.exe
HVideoSP.dll
LHPortal.dll
LQCTwn32.dll
QCTwn32.ds

There are no pictures files. This is Windows XP Professional in case you need to know.

Thanks again,

Jon

The webcam can save a lot of picture format, but, usually, the previews are in bmp form. As far as I know, can be tiff, gif, png.

What else can I say: do a search for all formats that camera can save: BMP, TIF, JPEG, PCX, PNG, TGA, PSD.

That helps a lot, since I have a Logitech quickcam also.

The photos are not stored in the camera.  For sure.

On my system, they are stored in "My Pictures\My Logitech Pictures\Pictures and Videos"

With my version of the logitech software (8.30), I have full access if, from the main software window, I select "My Logitech Pictures" on the right side of the application Window.  I can easily delete them from that window.

My camera is a Quickcam Zoom, the older white model (the later ones, which are not as good in my experience, are chome-plated).  But I think that all of the cameras, including your express, can use the same software, so you may want to get the latest software from the logitech web site.

My pictures are stored as JPEGs (*.jpg).

crissand: Thanks, but still nothing!

Watzman: I do indeed have the lastest version software available for this particular camera.

Thanks,

Jon

Do a search for a folder(s) with "Logitech" in the name, and look in those folders.

Hi,

I have done as you said. There were only two folders appear:

C:\Documents and Settings\All Users\Start Menu\Programs\Logitech
C:\Program Files\Logitech

I have had a look around in both and none have any previews in them.

Thanks again,

Jon

????

Ok, remember the previous suggest, where we did a capture and then looked for it?  [without success]

Let's try the same thing again, only this time look for *.* (any file), but use the date option in the search (find) function to limit the search to today (last 24 hours in some versions of Windows), and then use the "detail" view to sort the list of files found in date/time order.  The picture that you just created is going to be at the "most recent" end of those files.

Watzman: Sorry for the late reply, I've been busy the last few days.

I did however do as you suggested, with the same results. The only pictures that came up were ones I had transferred onto the computer from my digicam earlier.

Thanks again,

Jon

Something is wrong here, because the logitech quickcams have no internal storage at all, the picture is stored on the hard drive, and yet you are saying that when you search the entire computer for any new file (*.*, with any filetype) immediately after taking a picture, you are not finding anything.  It has to be on the drive somewhere, something is wrong with the search.

Watzman: I entirely agree with you! I cannot see what is happening here but I assure you the search turned up nothing at all of interest.

Jon

I've sorted this out myself by just using a different TWAIN driver. Thanks for all your help.

Jon

ok.
