help the acquisition of images only when the light is on

Hi, I need help to create an instrument.

I need to create an instrument to:

I have a black box with a camera. This camera will be connected to the pc via the USB port. When I press a pedal strong light comes througt it.

I need that labview shows an image in real time when the light comes and stops showing the image when the light goes out, showing the last structure that was light. It's like a system called last taken image.

for example:

I have a pedal that start a strong brightness. LV doesn't show any picture, when I press the pedal and lights in LV stars to show the image when I stop pressing the button LV displays the last picture or image that was light. If he starts another moment to press the pedal LV begin to appear the new images until I stop to press the pedal.

any idea?

Thank you

Jorge

that is going to be there to help you use

  • Acquisition of CL crashes when the image is too light?

    I have a strange problem and I can't be sure either the camera or the Board of Directors: basically, in any method of execution, when the image is too light, the acquisition stops and I get a timeout in MAX. It is with a PCIe-1433 and Point grey Gazelle. Blockage of the camera and restarting acquisition works very well. This occurs at any time, that the majority of the image gets to 80% brightness.

    To make things more confusing, this can sometimes be corrected by the passage of cable (the same 5 meters OR cable model, but just another); now, however, I have a couple of cameras that show that all cable and so I need to get it figured out. It would certainly be a problem of camera or a combination and so I contact PMP as well. Anyone has any ideas on this? Thanks in advance for any info!

    I would suspect that your CameraLink cables cannot meet performance requirements for speed of clock and the distance, that you are running. Unlike most new buses at high speed, the underlying mechanism of encoding on the wire for CameraLink has a characteristic resistance to noise (even among his own peers) depends somewhat on the actual data values are transmitted. Since the frame control signals are passed in the same channel as the content of the image itself, if there is some noise/interaction between them on the wire, they could cause problems of behavior on the side of the acquisition.

    If your camera supports the lowering of the frequenency of the clock, you might be able to check that helps the behavior. If it does, I recommend trying to replace the cables with superior quality-those. The CameraLink Committee now has a test of official certification of cables which is very comprehensive. I would say in ensuring that the cables you are using are actually tested for these certification tests.

  • How to integrate an audio to a Muse image file so that the music plays only when you click on the image?

    Hello! I'm looking for a way to incorporate an audio file (mp3 or quicktime) into a still image in my Muse site. Ideally, the audio would play only when you click the image, so that each image can contain a separate audio file. So important is that the audio file is not visible on the site (so soundcloud, youtube and vimeo doesn't work here). Is there a way to do this? Thank you, AR

  • Keep all information collection during the acquisition of images when you use the basic IMAQ package

    I did show a command of X from IMAQ image control that has the ability to overlay dots and lines on an image, but when I put my control of X in my loop of acquiring image collections information disappears with each new picture that I acquire.

    How can I keep the overlay in place and just update the control with the new image and does not overwrite data overlay? I tried the function of superimposition of fusion, but this doesn't seem to work.

    Thank you.

    Overlays are completely erased when you acquire a new image.  You can create collections on a separate image, and then copy to each new image overlays until you view it.  The other option is to re-create overlays for each new image.

  • Display success or failure of the images only in the user interface custom

    I built a user interface customized to my project VBAI 2010 that displays 2 images from 2 different cameras.  I want to have the "View menu" available for an operator to choose between images, only passed, only having failed, etc.  The view menu is using the default user interface, but when I build a custom one from one of the templates, this option is no longer available.  How can I get the view menu to show up?  If I can't do it, is there a good work around for this?

    This is the VI amended with an additional option for any display puts is not up to date.

    If you do advanced UIS Custom like this, you should definitely check out LabVIEW. You can even install it for evaluation to try... later, when you're not on the customer site

  • What is the importance of buffers in the Acquisition of images

    I think the question is explicit. I select the function set up IMAQ1394. It includes a command to define the number of buffers, usually they implements buffer is more than a video acquisition and 1 in the acquisition of images (I quote examples). but when I change these examples by removing the wire of the buffer total still image is acquired very well. This prompted me to ask the importance or the importance of buffers in the acquisition of images.

    Hello Asad,

    If you look at the detail help, the buffer for a setting configures VI is defined as follows:

    Number of buffers For a first acquisition, this parameter specifies the number of images to acquire. For a continuous acquisition, this parameter specifies the number of buffers that the driver uses internally.

    By default it is on, so you will always be able to acquire without specifying this entry.  For a first purchase, you will acquire the number of frames specified.  The display of the images, if you have a poster of the last image.  For a continuous acquisition, the number of buffers is defining the size of the buffer by using your pliers is.  So, if you set a buffer of size 1 rather than say 10, you have more chance to run through the buffer overflows.

    I hope this helps.

  • How to get the best image quality when you insert PDF into Word?

    I am able to insert a PDF file as an object in Word, but the image quality is a bit fuzzy.  Is this what I can adjust in order to improve the clarity of the image in Word?

    You can try to extract the images with the help of extract all Images or select only the parameters of the screen recording you get when you save in a DOC, but I think that the general result is that the image recorded with the same resolution as shown in the PDF document. It may be that you simply adjust your screen in WORD. You can look at the picture in WORD and see if it is used at 100% or some other resolution. Bitmaps are not very forgiving if the resolution is changed to the document and not as something other than the small number of fractions of resolution appears change.

  • Phone to download a lot of data via WiFi only when the charger is plugged - iPhone iOS 9.3.1 6s

    Hello

    Just today, I noticed that my iPhone 6s was download continuously at the speed of the network via WiFi only when is plugged in the wall charger or the USB loader on the computer. As soon as I stop charging the phone, the download stops. I have no idea what download and I'm a little frustrated because my connection high speed/wireless home is capped.

    Sync to iTunes on WiFi and iCloud backups are disabled. I had subscribed to 9.3.2 iOS beta on the registration by registering with my Apple ID last week, but I haven't added the certificate so that it can download OTA or via iTunes. I have no update available on my Apple store as well.

    I noticed the slowdown on my cause of internet connection of desktop computers that my phone of summer download something on wifi while he is in charge and I also saw the use of the network by using "System Monitor" app on the App store.

    Kindly help me to solve this problem.

    Thank you

    I did a factory reset on by phone by "Erase all content and data" and chose to set up as a "new iPhone" after reset done. There are now only apple applications on the phone, I connected to wifi with the charger plugged and the problem persists. I wonder if it was to be an apple iOS update, I am on iOS 9.3.1 and 9.3.2 is still in beta, I'm not sure if there is an apple update going on in the background.

    Kindly help.

  • Satellite M50 - charges the battery only when stopped

    My Satellite M50 battery only when stopped. Does this mean that when I work I'm still running on batteries, which of course carry out completely after 1 to 2 hours. Then I shut down the computer and it started charging again (orange led), and after a few hours, I still have a 100% charged battery.

    Of course, this means that the computer is not available. Until a few weeks ago it used to have the same problem if I disconnected the power plug then reconnected it: the battery needed to dump then to 0%, even if the power is connected, but now the problem is constant.

    I've updated to the latest version of the BIOS, I could find and even completely reinstall windows from the recovery disks, but the problem is still there. The computer is a Toshiba Satellite M50 - 126 model PSM51E, the BIOS is Phoenix BIOS v2.10

    Is it possible that the BIOS is damaged of some sort? I tried to reinstall V2.10 but he told me that I have the same version and it will not be installed.

    Hi lartech,.

    You can recharge the battery if you get into the BIOS and made the battery charging icon light?
    Are you using the original Toshiba AC/DC adapter and battery?

    In the worst case, it s a malfunction of the motherboard, and you have done what you can do: BIOS update and to install Windows from the recovery disc. If this doesn't help s a bad hardware work.

  • How the LED lights up when a threshold is reached, then turns off only when the value does not reach the threshold for a while?

    Hi, I want to write a program that can turn on the LED when a range of value, this is the threshold and only when the value does not reach the threshold for a period of time, say 5 seconds, then the LED will turn off, otherwise it will remain. How can I achieve this in labview? Can someone help me? Really thanks!

    I assume that you use a while loop to keep the updated value.

    Add a record to offset to your looping it initialize with a U32 (time in ms)

    Add the registry to offset to your loop that keeps the previous value of your bool

    When your reaches the threshold value => the light and set the current time in your shift register.

    In the next iteration of the loop weather check value is still above threshold

    => Y-online previous set to true?

    => Y-online the next iteration

    -Online N => turn switch on and set the current time in your shift register.

    -Online N => subtract the time current less time shift record-online more then 5 seconds?

    => Is => keep turning on

    -Online N => turn given

  • Compaq 6710 b: my HP Compaq power on only when I plug in power. Don't turn on with the power button / stop!

    I have a laptop HP Compaq 6710 b... Its more than 6 years...

    The problem is really annoying... The laptop powers on only when I force taken into the spindle of the charger and the laptop works very well after that...
    But the laptop never turns on when I try to power by pressing the power button!
    I did not understand the reason why...

    Any thoughts on this problem?  Help!

    There are no settings in the BIOS that affect the use of the power button.

    The power button works at the level of the material (firmware).

    By pressing the button translates the action of the Commission of the conditions of the logic system.  There must be voltage at specific points in the power circuit. If the voltages are not present, then the power button does not work. This can be caused by a failure resistance, mlcc capacitor or a bad solder joint, if the power button has been tested and shown to work normally. Fluff even could cause this to happen. This can help out-performed by Visual inspection and using a multimeter.
