Trouble saving image from CCD

I have an Andor Newton EMCCD Camera which I am interfacing with Labview 8. I have modified a VI supplied by Andor for capturing cooling the camera and capturing data. The data returns from the Acquisition vi as a 1D array. It is reshaped into a 2D array and then viewed on an intensity graph that is 1024 x 256 (the number of pixels on the camera). This works fine- the image is shown as blue and black in the intensity graph (although greyscale would be preferred). If I try to flatten pixmap and save the image as a jpeg, the image looks different. It seems to have lost detail, even if I turn it into a 24 bit pixmap.
Below is an image that I got using Andor's software. You can see two emission lines showing as bright regions across a grey background. The same image is shown as blue and black on the Labview output, and the bright lines are very hard to distinguish.
I'm not sure what I am doing wrong. How do I take data acquired from the CCD and output it as a jpg? Why does it look great as an intensity map but it doesn't work in jpg format?
If you want me to post the vi, just let me know.

ANDOR Image (desired):
LABVIEW image (want it to look like Andor image):

It's probably a bug somewhere with your VI. So we'll need to see that (with a sample array of the data, that works in the intensisty chart but not saved).
You can post attachments and link to them to add pictures. Like so (your image host doesn't like hot linking).

  • Im having trouble saving images from photoshop to my samsung tablet any ideas

    im having trouble saving photoshopped imsges onto my samsung tablet any ideas ?

    I have no knowledge of the Android OS.  I do have an iPod and its OS iOS is not really comparable my Windows  OS.  The iPod does mount as a dive on windows and the iPod camera roll is accessible. The jpes images can be copied to my pc.  However the PC does not have access to the iOS file system even apple user don't have real access the iOS file system.   Image need to be synced between the iPod and PC through iTunes sync.  Itunes messes with your PC images and creates some sort of image database and syncs that database between PC and Apple mobile devices.  There are also apps that help you share file between PC and Apple mobile devices.  I have no idea how files are shared between PC Operating Systems platform versions and Android OS versions.  Photoshop may not be able to save to Android files system.  Photoshop Can not save to Apple mobile devices. Photoshop may be able to save to Apple's Mac unix file system through some form of network share.
    How does one share files between Android devices and PC OS devices?

  • Trouble saving images from safari

    I'm running into a strange issue and wondering what's going on. Sometimes (not every time) when I save a jpg from safari, it will show up in my saved photos but it will be blank, all grey with a camera icon and jpg under it. Then, any time I save a photo after that it doesn't show up.
    Deleting the blank photo and saving it again works, but this is a hassle as I never know WHEN the error will happen and would rather not check after every photo to see if it occured.
    Any ideas why this is happening? It's not the image itself since if I try again after deleting it, it will save properly.

    I'm having this issue and have a detailed post about it as my first post on this forum.    Good luck.  I really hope someone can help us out with this...

  • Saving image from CCD Camera (without IMAQ and Vision)

    Hi,
    I am using the basic Labview 7.0 (no IMAQ and no Vision). I am triggering a
    CCD camera (Megaplus ES 310 Turbo) from my NI acquisition card and the
    signal goes to the triggering input of the camera. How to save the file
    captured by the camera under labview? I found the "Write a jpg" VI but how
    can I refer the image data to it?
    Any clue is truly welcome.
    Thanks
    Mathieu

    Hi Matthieu,
    What kind of format is your CCD image in? If it’s in some sort of a pixmap (2D array) then you can use the Flatten Pixmap VI in All Functions >> Graphics and Sound >> Graphics Format to convert the pixmap to an image data cluster. You can then pass this image data cluster into the Write JPG VI.

  • Trouble saving images from email 'no permission'

    I'm trying to save some images I've been sent  on email but a message comes up saying that I can't save them as I haven't got permission. I'm not sure why this has started to happen or how to rectify it.

    Nope, unfortunately you can't.
    I guess it was because you can just go on any computer and save them there.

  • Saving images from LR Mobile with edits.

    I'm having a bit of trouble saving images on my ipad with the current edits.
    To me it seems I have to manually sync the edited image first, otherwise Lr just saves a JPG of the original image to my photostream rather than a copy with adjustments on it.
    Am I missing something or is this the way it works?
    Thanks for any insight.

    Correct. As long your image is in Develop mode (same with presets and crop) and you would like to share from there you need to maually force sync your changes first. This is already logged as in internal bug. Thanks, Guido

  • Trouble saving images on cRIO-9022

    I'm having trouble saving images on my RT target cRIO-9022 (VxWorks). I get "error 53 occurred at Write GIF File.vi LabView: Manager call not supported" when running the code. What I'm trying to do is save periodic snapshots of front panel charts/graphs locally on the cRIO and download them at a later time.
    I've also tried some of the report generation VIs and had broken arrows and compile errors. from what I've read in help and online, It seems perhaps it is not possible to do what I'm trying to do with my particular target. Is there any reason that I shouln't be able to save images locally to the RT target? has anyone else had a similar problem generating reports or saving images on the cRIO-9022?
    Thanks for any help you can provide,
    truth204

    I've run into similar problem before... I was unable, at the time, to find a good workaround for saving front panel images to file on RT because the necessary report generation functions were unsupported on the RT environment. If you are just saving data from charts and graphs, you might want to consider saving the data as a binary file or a spreadsheet/.csv style file. This is ultimately what I did in my RT application, and then I created a separate desktop application that would read the data from those exported files and reproduce the charts/graphs that were created on the RT target.
    Here is a KB describing your error, for reference: http://digital.ni.com/public.nsf/allkb/39B5B135F32902388625723B00683B27

  • Trouble Exporting Images from Lightroom 3

    I am having trouble exporting images from Lightroom 3 with my User Presets. Error Message: The file could not be written. (1). It has always worked in the past but I just bought a new Mac and had everything transfered to it. Everything else seems to be workin fine. Any solutions?

    Sometimes on new computers, the permissions in certain folders are not set up to allow you (the only user) to write files. It's worth a check.

  • I saved images from an imessage.  now when I open Imessage, the pictures will not go away. When I press "done" the pictures remain. Cannot send a message

    I saved images from an imessage.  Now when I open Imessage, the pictures are displayed on the screen.  When I click on "done" the images do not go away.
    Therefore, I cannot send a message.

    Quit the app completely and try again. Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar.
    Or try this.
    Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

  • Why am I having trouble saving images consistently with Photoshop 5

    I have been trying to save images from one file to a final modified one.  Two problems:  1) Some images are unedited and save sometimes but not always.  Why?    2) Some are a combination of an original plus a transformed close-up from another image.  When the finished edited image saves, it is much smaller than the few unedited images that did successfully save.  Why?
    The images are digital photos of my jewelry.  In order to decrease the number of pages on my impending website, I am attempting to transfer, when one is available, a resized close-up to the other shot of  the full set (close-ups are what sell the work!).  Some of the images show 25% on the top bar but that doesn't seem to make a difference as to whether it will save or not.  Others (I notice they seem to be more horizontal images) are 16.7% ?  Does anyone still use Photoshop 5 or is this a fix that is so basic, it is the same for newer editions???  Anyone?
    Also, while we are on this page:  I tried to upload example images to illustrate what I am trying to do but kept getting an error message.  Any advise?

    For web use the resolution of the file has no meaning only the pixel dimensions.
    It depends on the site your uploading to, some have specific sizes for the photos (pixel dimensions) that is usually listed somewhere on the site, but to give you a rough idea, the size might say something like no bigger than 800x600.
    That would mean 800 pixels x 600 pixels (resolution doesn't matter) and the usual file type is jpeg. The 800 is for the long side of the photo.
    To see the pixel dimensions of a particular file, go to Image>Image Size and i agree with the others on the % being the viewing (zoom) percentage of the image on the screen and doesn't mean anything as far as saving files. 100% is actual pixels.
    If you double click on the zoom tool in the toolbox that % should change to 100% (actual pixels) In the photoshop 5 help, look under Looking at the Work Area-Viewing Images.
    Do any of the files your saving have layers (more layers than just the Background layer)?
