Grab images from a IP camera

---BACKGROUND---
We have very little experience with programming for the LabView, but good experience with programming in general.
---SETUP---
In one end we have the newest LabView (8?) that is connected to several OPC driven PLSes.
In the other end we have a piece of custom hardware that grabs images from several analog cameras (surveillance machine)
We need to send the image from the surveillance machine to the labview
software as easily as possible. We have access to the sourcecode for
the surveillance machine to writing a custom protocol to send images is
no problem, the problem is the labview end.
My question is if there is a way to make labview connect to a machine
and download images from it, the exact protocol is no problem since we
can customize the hardware completly, a llI need is a connection where
images come streaming to it.
If not then maybe there is a way to program the labview to do the following;
Connect to a machine on the internet
Send commands to the connected machine
Receives images in a loop until connection is broken
Hope anyone got any clues as to what I am trying to accomplish here.
Thanks in advance

nyc thanks for your time,
Here is my code, along with the C# example code from the vendor.
FYI the sample code from the vendor did not work on the customers machine either, just showed a black screen. I installed VS2010 Express C#.NET on the machine to test if I could grab images from the vendors example and no joy....didnt work.

How to Snap/Grab Image from 1394 camera and display the Image in CWIMAQVIEWER in VC++ ?

Hi,
I have : - IMAQ1394 2.0.1
              - NI Vision 7.1
In VB, I can Snap/Grab Image from 1394 camera and display the Image in CWIMAQVIEWER :
    Dim Image0 As New CWIMAQImage
    imaq1394SnapCW(sid0,Image0)
    CWIMAQViewer1.Attach Image0
Now,How can I do this in VC++6.0?
    I tried:
              C_CWIMAQImage m_imgViewer1;
              m_imgViewer1 = m_CWIMAQVision1.CreateCWIMAQImage();
              m_CWIMAQViewer1.Attach(m_imgViewer1);
              imaq1394SnapCW(Sid,m_imgViewer1); <--there is no "imaq1394SnapCW "function in VC++,why?
    Please help me!
    Thank you!

For people looking back at these old posts regarding
CWIMAQViewer - it was not made to be used in the C environments and is made
for VB.
Refer to the following locations for displaying images in C
environments:

I have an older imac with os10.4.11. Will it transfer images from newer digital camera using my iphoto when on the camera box it specifies a mac os of 10.5 or above?mo

I have an older imac with OSX 10.4.11. Will it transfer images from newer digital cameras on to my computer via my iphoto program when the camera box states that the required mac OS is 10.5 or above or is that only if you wish to load the camera manufacturers own image processing program?

Which camera are you speaking about?
Why are you on such an old version on OS X?
With the information provided, I am inclined to say, no.

Raspberry Pi B+ capture a image from a video cam

Hello,
is there any way to capture a image from the video camera. I didn't find any media class for video. Nor did I find any Runtime.exec to use a native linux command.
Did I overseen something?

Hi Klaus,
There a few ideas in design stage, but nothing solid enough to talk about. And actually it should not have been possible with older ME as it's specifically prohibited by the spec. I mean native methods in Java applications. Of course there may be other means to communicate with native applications, like files, sockets etc. But no direct calls
The date for ME 8.1 GA (General Availability) release is not confirmed yet. But it should happen quite soon, stay tuned
Regards.

Receive image from two web-cameras

Hallo all.
I have LV 7.1.1
I have two web-cameras which are connected to USB1 & USB2.
How can I see two images from two web-cameras or more in LV at the same time?
With respect

Aleksandr,
The IMAQ for USB driver communicates to the 3rd party camera driver using Directshow. There is an IMAQ USB Property Page VI available in LabVIEW that gives you the ability to open the camera configuration page of the 3rd party camera provided that there is one available. Depending on the vendor, you may or may not have access to change the resolution of your camera through this property page. I would contact the manufacturer of the camera to find out if there is a way to do this.
In case you are curious to know where to find the IMAQ USB Property Page VI, right-click on the block diagram and go to Search in the upper right corner of the palette. Search for "IMAQ USB Property Page" and the corresponding VI will show up in the list below it.

Lightroom not merging and sorting images from two different cameras - help please !!

Hi guys,
I need some help here. I've just imported a few thousands of images form two different cameras, however Lightroom simply sorts them by camera only. (i.e.. images from the first camera, all sorted by capture time, then come images form the second camera.)
The cameras are the same brand and model, times are synchronised, but the images refuse to merge and sort. I've tried putting them in the same folder and importing, but that doesn't do it either. I've been doing this for years and it all worked fine, till today. Does anyone know whats causing this, and how I can fix it?
Thanks in anticipation.
Latch

Hi John,
View > Sort > Capture Time is checked, The cameras are in sync down to the second, and images from both have been merging and sorting fine for over two years, till today. Sort order is all set to capture time in all modes and views, but its still sorting first by camera.

How to acquire image from S-video camera

Hi,
I have a camera with S-video interface. I use a S-video to USB adaptor to acquire the images from my camera. Popular video editor/maker softwares, for example Windows Movie Maker, ULead VideoStudio, etc.. are able to display the video capture from my camera (using the same S-video to USB adaptor). Thus, I think the adaptor transferred the camera to an USB Directshow camera already? However I cannot grab images/video using Labview. I have installed IMAQdx, and I can use the same LabView VI to grab images/video from my USB camera.
Is there any suggestion for my case?
Thanks.

Make sure you are using the right color channel, in most cases YYUV will not display. Use RGB. Also try changing the resolution settings.

When I put images from my digital camera to iphoto they register as jpegs with only 72 dpi. How can I get them to be 300dpi?

I have a mac osx 10.6.8. iphoto 11 version 9.2.3.
My camera is a Canon Power Shot SX700HS.
I want to send high res. photos to a company who require 700dpi.
When I attach my camera to my mac they turn into jpgs and then
when I try to send them by email they come in at 72dpi.
Can anyone advise me on the best way to send these photos?

I notice that images on Image Capture come in at 180dpi.
180 dpi isn't terrible, but defined edges that aren't perfectly vertical or horizontal will show jaggy pixel stepping. Not real obvious, but you'd see it. Overall, the picture would have a slightly pixelated look at that resolution.
The maximum size picture your camera can take is 4608 x 3456 pixels. If you set the resolution to 300 dpi, that makes it 11.52" x 15.36". So without scaling/resampling the image up to keep it at the vendor required output resolution of 300 dpi to get larger sizes than that, your camera is best for 11" x 14" images or smaller.
Whatever image editor you use to size your images, you need to finalize them at 300 dpi, which is what your service requires. If you were to send them for example an image sized to 16"x20" at 120 dpi, what their system will automatically do is scale the image to 300 dpi before printing it, which will cause pretty noticeable softening and pixelation on the final print.
For that camera, it makes more sense that it comes off the camera as 180 dpi. That must have been Mail that was scaling them down to 72 dpi what added as an attachment.
So how do you change the resolution? One way is with Preview. Here I'm working with a test image to show the difference in what happens depending on how you size it. I've purposely changed this image from it's original 300 dpi setting to 120.
Open the image and choose Tools > Adjust Size.
This image is 1816 × 1419 pixels. At 120 dpi, that makes it 15.13" x 11.83". If I reset the resolution to 300 dpi, not resample, the size changes to 6.05" x 4.73". It does that because I turned Resample image off. When you do that, the image doesn't physically change one bit. It still has the same number of pixels in the height and width it started with. All you've done in such a case is tell the output device to use 300 of the pixels per inch instead of 120. Since you're using more of the same original number of pixels in less space, it becomes effectively smaller.
Now let's say I want this image to be output large enough for an 11" x 14" print, but also need it to be 300 dpi for the vendor. To do that, I need to resample it.
There isn't enough pixel information in the image to do that without resampling up. Or said another way, adding more pixels than existed to begin with. Notice the scale percentage is 232.6, which directly translates to adding over twice as many pixels to the image (232.6 percent) as it started with in order to achieve 300 dpi at 11" x 14". Notice too of course that the size of the file will go from 7.8 MB to 55.7 MB (sizes are normally displayed as how it would be for an uncompressed format such as TIFF). The image will now have 4223 x 3300 pixels instead of its original 1816 × 1419. Such large resampling going up also makes most images soft and pixelated looking. Though since CS6, Adobe drastically changed the scaling algorithm. Larger up-sampling of images is much better than it used to be. You can scale most images up quite a ways before they start looking really bad.
I know this is a lot. Hopefully, not too confusing.

Aperture Recognizing RAW images from newest Canon Camera S95?

Aperture (3) will not recognize the RAW images form my Canon S95 -- anyone know how to fix this or will Apple come out with an fix? It recognizes RAW from my Canon Xsi. Also iPhoto won't recognize it either.

RAW support - for any camera - comes from the "Digital Camera Raw Compatibility Update" components. These provide central support for any application that reads photo files. The currently supported cameras are listed here:
http://www.apple.com/aperture/specs/raw.html
In case you're interested, the most recent releases are:
http://support.apple.com/downloads/#digital%20camera%20raw%20compatibility%20upd ate%203
will Apple come out with an fix?
For Canon, almost certainly. Unfortunately, your only recourse is patience - nobody here can tell you when the next release will be made.

Won't download all images from my sony camera...only 6 out 0f 170, says rest of them are "unreadable j.peg format". Help!

Help! My Mac will not download all images from my Sony digital camera...well, it downloaded 6 out of 170, then said "unreadable j.peg format". This is the second time I have had this problem with this camera. Up to this second time, I have not had a problem with downloading. Now when I plug the camera back in in, it shows empty frames of pix on Mac screen, but pictures are still on the camera. Any suggestions?

See if you can use Image Capture to upload your photos to a folder on the Desktop. Once you have them off the memory card reformat the card using the camera, take some photos and try again.

Transfer images from mac to camera

Hi, im trying to transfer images from my macbook pro back to my camera. When i hook up the camera the only place i can see it is in i photo and it wont allow me to transfer in that program. The camera does not sure up on my desktop as a flash drive would.... how do i open the camera in a finder window that will allow me to click and drag photos back to the camera? is this even possible? im using my macbook pro with osx snow leopard
thanks for the help

Remove the memory card from the camera and insert it into a USB card reader. it should then be mounted on the desktop in the Finder, and you copy images onto it. No bets on whether the camera will display them as expected, though. It's generally safest not to make any modifications at all to the contents of a camera card while it's connected to a Mac. The result of doing so is often that the camera won't be able to read or use the card.

Stop motion animation help using images from a digital camera...how tricky is this?

I'm teaching a media arts course for the first time, and I'm trying to figure out how to use images taken with a digital camera, import them to Premiere Elements 7, and put them in the timeline without having to shorten the length of them. As soon as I drag an image from the project bin onto the timeline, it automatically plays for 5 seconds, and I have to try to shorten it to one frame length. If that's what it takes, this process is going to take a lot of time, because the students are going to be taking several hundred photos. If I edit them in the preview, it's still just as difficult. Is there any way to change the settings before I import the images so that they automatically are one or two frames in length on my timeline? Your help would be GREATLY appreciated.

Welcome to the forum.
As Steve points out, setting the Edit>Preferences>Still Duration BEFORE Importing, will get what you want.
When doing Stop-Motion, I find that a Duration = 3 to 5 Frames, works best, but that will depend on the images, how far apart, they were shot, and the exact effect that I want. It might take a little experimenting, to get things correct to both your eye, and to the images from the camera.
Also, Scaling the Still Images, prior to Import is a very, very good idea, and especially so, with Stop-Motion, as you will have lots of them.
Good luck,
Hunt
PS - if you are using Transitions, between the Still Images, you will want to alter the Duration of those too, prior to applying them.
