Blur video frame with NI PCI-1411 and JAI CV M-300 camera (urgent problem)

Hello,
I am new with Vision and I need some advice with a problem, which I encountered.
I have a computer with integrated NI PCI-1411 board, which is connected to a JAI CV M-300 camera. I am measuring a steel part which is positioned in a dark chamber. The part is put on a glass board and is illuminated from underneath with light.
The part is moving. I have to measure this part when it reaches the camera region. I have made a test with not-moving part and everything is perfect. Now, when I move the part I get blur frames from video (with these no part measurement is possible). I need specify, that the camera has no trigger, so it makes video all the time (this video is later inspecting with Vision Builder).
I have tried to change parameters in MAX, but no involvement. I have found no proper icd/file for the camera.
I also could use a SONY DXC-950P camera, if this is better.
How can I eliminate the blur from video frames? Or what am I doing wrong? Is the camera not good enough? Camera + trigger would get better images.
I have attached the video frame with moving object (static) and the blur video frame with moving object (dynamic).
Please give me a answer or ideas as soon as possible.
Thanks.

You are using an interlaced camera. It takes half the picture (every other line), waits a split second, then takes the other half of the picture (the other lines). When it puts the two images together, you can see the two positions it was in when the images were taken.
The best solution is to use a non-interlaced or progressive scan camera, which takes the entire image at one time. The Sony might be this type of camera, since it has a P in its name. I didn't look up the specs.
If you can't get the right kind of camera, your only other option is to use fields instead of frames. One field is the half image taken at one time. The image will be half the height of the original image, though, which can mess things up.
Another possibility is the reduce the resolution of the image. If you take every other pixel in both directions, you will have a very clear image that is half the size of the original. You can do this with Extract in LabVIEW, not sure if it is available in VBAI.

Is it possible to remove blemishes from video frames with photoshop cc?

Is it possible to remove blemishes from video frames with photoshop cc?

Again, show us reference screenshots and we will advise. Otherwise this could become an endless theoretical discussion. Depending on what you want to do you can import the video directly using Layer --> New Video Layer e.g. when covering up fied spots with a brush blob on a layer on top of the footage, but you may also need to create separate layers for each frame using the Frames to Layers script so you can paint on each of them individually. There's really too much we don't know and the possibilities are potentially infinite...

I downloaded some videos to Premier Elements 13 from external hard drive but now the external hard drive is damaged. I tried to open the videos on the organizer which it shows the video but with a yellow ? and says missing file. Is there anyway I can open

I downloaded some videos to Premier Elements 13 from an external hard drive but now the external hard drive is damaged. While setting up my new MAC the external hard drive was dropped and I have been told by an outside source they could not retrieve the files. It had 4 years of photos and videos on it. I remembered that I had downloaded some of the videos from the external hard drive (before it was broke) to Adobe Organizer 13 when I installed the Adobe 13 on my MACOS X 10.9.5. I tried to open the videos on the organizer which it shows the video but with a yellow ? and says missing file. Is there anyway I can open these videos?
Any input is greatly appreciated!! I am sick over losing the videos and had a little hope on Adobe Organizer until I was unable to open them. I am thinking it is due to my external hard drive not being plugged in. I thought when I transferred from the external hard drive to Adobe 13 that it would be there without the external hard drive needing to be attached but maybe I did something wrong.
Thanks again for any help!!!!

It had 4 years of photos and videos on it.
To what did your camera record those photos and videos - camera's internal memory, inserted memory card, other?
Any remote chance that the latter may still exist for you to use to download the camera files to your new external hard drive?

with photo stream on and importing pictures from your camera into your Ipad - after 30 days the pictures will be removed from photo stream, but will the pictures still be in your Ipad ? andy

To my knowledge, pictures in photo stream stay there untill there is more than 1000 of them, then after that the oldest ones are removed from photo stream. If your photos have synced to your devices via photo stream or manual syncing they will be there until you elect to delete them.

Triggering problems with IMAQ PCI 1411 using NI-IMAQ 2.6 drivers

I am having problems with the NI-IMAQ triggering mechanisms. I would like to use imgSessionWaitSignalAsync to register a call-back function to be repeatedly called on rising edges on the external trigger line. Now the external trigger line is connected to a photocell that is low when there are no objects in front of it and is high when there is an object in front of it. Unfortunately, when running my application, the callback function is not always triggered when an object moves in front of the photocell, and it is often triggered when no object is in front of the photocell. The callback function is not called anywhere else in the code.
An engineer at my company hooked up an oscilloscope to the trigger l
ine and we found that the photocell performs as expected. So I am looking for help to ensure that every time an object starts to pass in front of the photocell, the callback function will be triggered.
System Details:
Windows 2000 PC
Visual C++ 6.0
2x IMAQ PCI 1411 installed(one is revision A, the other is revision C.) I have the same problem even if I switch to the other card.
NI-IMAQ 2.60.0 drivers
Thanks in advance,
Michael

Bruce,
In fact that was my problem. The XC-73 operates at 30 Hz. My strobe
lighting was not triggered at 30 Hz. Once they matched, the
interlacing problem I described went away.

Can I do a 3 way video chat with two iMac users and 1 PC user?

Hi,
I'm due to have a video conference in a few days and I suddenly realized that one of us has a PC and two of us have iMacs. If the PC user were to get AIM, would it be possible for her to communicate with the two of us and can the two of us communicate with and see her? We live in 3 separate areas so we will be using three separate computers. If it is possible to do this, what do we all need to do? Also, I have iChat 5.0 and the other iMac user has whatever came with Tiger. I have done three way video conferences before without a problem but we've all had iChat. Thanks in advance.

Can you freeze frame with the imovie app. and save the freeze frame to a picture

Can I freeze frame on the iMovie app and turn the freeze frame into a picture?

Experiencing the same issue. Fired up iMovie for the first time today and created 2 movies. The first was 35 seconds long and the 2nd was 1 min 45 seconds long. Got all my pics loaded up and added a song from my personal collection. Plays perfectly from the phone. The problem occured when I tried to export the larger movie. The first time I tried, it sat at the exporting movie status bar (without moving) and then closed the app. After relaunching the app, it told me that my audio file had been removed from the phone. After closing and re-opening the iMovie app again, my movie project played fine through the app but as soon as I tried to export again it rebooted my phone. I tried exporting on all 3 size options (Medium, Large, HD) and it did not matter. I tried multiple songs thinking perhaps that was my issue, but each one did the same thing. I tried the lock-screen time-out fix but that didn't help either. I have no problems exporting my smaller movie file (35 seconds)using any of the export sizes. This leads me to believe that the issue is soley related to the length of the project...or perhaps the number objects located in the project. In either case, it's definitely an app issue. I do love the app though...when it works.

How do I set up a PCI-1409 and two Sony XC-ST50 cameras for synchronization and asynchronous reset?

Hello! I am using a PCI-1409 with two Sony XC-ST50 cameras. I need to use a single trigger to capture an image from each camera simultaneously. I know I need to gen lock the two cameras and use asynchronous reset. How do I do this specifically? How do I connect the cameras to the PCI-1409 and what settings do I need to set on the cameras and the PCI-1409?

There are a few great tutorials on the NI web site. The first discusses genlocking multiple cameras together. It is in the context of the JAI CV-M1, but all the concepts can be applied to other camera types. It is called "Genlocking Multiple JAI CV-M1 Cameras" (http://zone.ni.com/devzone/conceptd.nsf/webmain/7A6B5853548850E886256C21005B1413?opendocument). Another turtorial I suggest looking at is "Advanced Analog Triggering and Synchronization Techniques" (http://zone.ni.com/devzone/conceptd.nsf/webmain/A387B5C0AC6F6F4E86256C87005FCDDF?opendocument). This tutorial has a section which discusses triggering and synchronizing with multiple cameras. The last tutorial I recommend is "Multi-Camera Acquisition"(http://zone.ni.com/devzone/conceptd.nsf/webmain/D91BAC1317F9D
0A686256C9300769A0D?opendocument) This discusses how to synchronize and program multi camera acquisitions on the 1409.
Hope this helps!

What causes blurred video, I'm using a 1411

I am using a VCR as my video source. Using a HL Grab acquisition. Performance is great. Once in a while my image gets blurred. I'm including a sample. Also, I am seeing a bowing of the image toward the top. What can I do? Thanks!

The blurred image looks like the odd and even fields have been reversed. I'm not sure why it happened though. The bowing at the top of the image is related to the timing signals. I suspect both are related to using the VCR as the source. VCRs do not produce high quality video signals by nature. Perhaps a higher quality VCR would help.
It might be worth running the same section of tape twice to see if the blurring occurs on the same frame every time. If it does, it is something on the tape. If not, it is the VCR.
