PCI 1422. Grab an image with 1 pixel height.

Hello.
I'm trying to configure my PCI-1422 board to accquire an image from my custom made line scan camera.
My camera sends a frame of 1 pixel height (24000px width) to the board. Every 1.9msec (so i should get approx. 526 fps).
The framegrabber recieves 3 signals: data, pixel clock (12.5MHz) and frame valid signal (i connected it to Enable A pin of PCI-1422).
The issue is that MAX says to me, that the total fps is 263.
When I try to get image data in my application (c++) i may recieve even less - only 1/4 of total frames.
Could you tell me how to configure *.icd file to be able to get 526 (24000x1px, 8bit) fps with my camera?
Is there any problem with my c++ code?
You may see my application and *icd file attached.

Alvern,
How many clock counts rae you waiting between frames? Have you tried decrasing the ROI further? You got it set 8 pixels shorter than the actual ccd, have you tried setting it 100 pixels shorter? What about 1000? I imagine you're interested in preserving as many pixels as possible, but try testing acquisition with shorter ROI's just to see if a sufficiently short ROI will allow you to acquire at the full frame rate.
If adjusting the ROI in addition to enabling fast rearm and Non Continuous Line Enable does not allow you to acquire at the desired frame rate are you able to decrease the frame rate? If so, what frame rates have you been able to acquire at without losing frames?
Also, though you are interested in continuous acquisition, have you tried snaping a finite sequence of images? Try snapping a finite number of images and storing them on the frame grabber to see if you are able to acquire at the full frame rate.
I suspect altering either the ROI, the frame rate, or the acqusition mode and buffering location will allow you to acquire without missing frames. Would you be able to test these and post your results?

Images with negative pixels value

Consider a simple black (0) and white (255) image composed by 3 vertical bands : the first is white, the second is black and the third is white. Image size is W columns by H lines. Band width is W1, W2, W3 for bands 1, 2 and 3 respectively (W1+W2+W3=W).
Consider now a first order edge detecting operation, for example Sobel for vertical edges :
1 0 -1
2 0 -2
1 0 -1
The corresponding edge image is composed of H identical lines (because the image is only varing horizontally). Each line is 0 everywhere, except on transitions : on column W1, there is a positive value of 4*255 and on collumn W1+W2 there is a negative value of -4*255.
Using the following java source code, we obtain an image which have only the positive (>=0) part of each line :
Image img = (new ImageIcon("bands.png")).getImage();
BufferedImage bimg = toBufferedImage(img); // not part of JDK1.4
ConvolveOp sobel = new ConvolveOp(new Kernel(3,3,new float[]{ 1, 0,-1,2,0,-2,1,0,-1})); // vertical Sobel filter
BufferedImage bimg_cont = sobel.filter(bimg, null);To have an edge image that contains the negative part of edges, we do need a specific image format with specific ColorModel and SampleModel. Ideally, we will need a grayscale image (1 sample/pixel) where all elements can represent values from -4*255 to 4*255. So we need a signed type like DataBuffer.TYPE_SHORT, DataBuffer.TYPE_FLOAT or DataBuffer.TYPE_DOUBLE.
Note : it is possible to apply the filter twice, with a mirrored filter, but time to compute will be also twice the normal computational time (very inefficient).
Now, this is the question : do anyone have a solution to compute a sobel filter (or any other filter type which produces negative values) with a resulting image containing positive and negative values ?

The problem is the size of the number you have to work with. You can store values ranging from 0 to 255 (the max index for a byte-sized variable) so the total numbers you can store is 256. However, if you want to go from -255 to 255, thats about 512 values, which is twice the size of your max. You would need one more bit on that variable to do that. You could make the far left variable be the positive or negative sign (know as a signed variable) which is how computers do it anyway. The only drawback is it will only range from -127 to 127, which is half as much detail.

Images with width and height

There is a way to insert an image inside of the html code
with width and height already? I mean, now, if I want to insert an
image at the code, goes only <img src="images/test.gif" /> I
d like that if I insert an image it goes as: <img
src="images/canto_topo.gif" width="8" height="29" />
is possible in dreamwaver to do that?
Thanks!
Vismona

If you insert the image using the "Insert Image" function, DW
will
automatically insert the width and height.
Or, if you'd rather insert them the way you are, in the
Property Inspector
on the far left, click the dimensions next to the Image
field, and DW will
automatically add (or correct) the width and height.
Hope that helps,

How can I properly export an image with corrected pixel aspect ratio?

Hi, I have a bunch of .png screenshots from old MS-DOS era software that I wish to convert to a 0,8 pixel aspect ratio to simulate the stretch from old CRT monitors.
I can easily preview it by enabling the pixel aspect ratio correction under the "View" menu, and it looks great. But if I try to "save as" the file as a .png or .gif, it looks blurry and horrible:
Any hints on how to do this?

Ok, thanks letting me know. Only last thought is a screen cap of image 2 (that I believe you want) saved to png.
There's a program called Greenshot that would use the Print screen key and allow you to marquee select and save the shot as a png file. Greenshot - a free and open source screenshot tool for productivity
That's for Windows, Cmd-Shift-4 on a Mac does the same thing.
I know it is a pain if you have a hundred of these, but I suppose if you are not in a big hurry you can get it all fixed up.

Raytheon 2000b camera with PCI-1422

I am trying to use a Raytheon 2000b camera with PCI-1422. I have downloaded the attached doc and icd file from NI.
1. As far as I now there is no proper NI cable for my camera, but the pinout is described in the doc file. I would like to purchase a cable, and solder a connector on it for my camera. Which cable should I choose, if I need the following pins on the PCI-1422 side: 1-32, 41-46, 49-50, 93-94, 99-100?
2. The icd file supports image acquisition only, attribute settings via serial line are not contained. I would like to add this feature, but I could not find any description about the icd files. Where can I find a document that would help me?

My problem is solved now.
But I don't know what is the exact solution.
The camera & cable provider and me tried as below.
try-1. connecting tm-1320-15 and 1422 with serial-enabled cable
try-2. changing 'OnBoardClock(20)' to 'OnBoardClock(25)'
With only 'try-1 ', it failed. but additional 'try-2' we could snap and grab the camera image.
And now, I can get images without serial-enabled cable, regardless of OnBoardClock speed.
I think the camera has been initialized with max's parameters(same as icd file) when the serial commnunication had enabled for the first time.
(I'll verify this assumption with new tm-1320-15 later.)
Thank you.
Tip : If tm-1320-15 and 1422 makes error because of parameter mismatching, reset the tm-1320-15's power.

Controlling PCI-1422 with Labview instead of MAX

Hello Experts,
I want your help in one of my problem. I have a camera from Sensors Unlimited which is SU-640 1.7 RT-D and a NI parallel card PCI-1422. I can use and acquire data with MAX from the camera but I want to operate,use and acquire images from the camera using LabView. Is there any way of exporting or using the camera with Labview instead of writing a fresh code in LabView?
Does LabView offer any support or reads automatically from PCI-1422 or any possible solution that I get the block diagram code for using this camera in LabView.
Please let me know, reply.
Any help or suggestions will be highly appreciated.
Thanks in advance!

Thanks but again it requires writing and struggling with coding and experience on LabView skills.
Just wondering something easy. I tried one of the example and it worked actually but I am trying to get more ideas or options to make it look better and impressive.
You want something and easy and doesn't require any effort on your end? Hire someone who knows how to program in LabVIEW.

Section of the data collected with PCI 1422 card connected to a CCD camera looks step-like

I am using the PCI 1422 card with a DALSA CA-D1-0128T camera to acquire and save fluorescence data from a heart stained with a potentiometric dye. The camera is set to work at 490 frames per second. My acquisition program (made using a producer consumer loop in Labview 2009) works fine most of the times, but sometimes a small section of the collected data looks step-like (not continuous). I have attached herewith a word document containing a snap of the data. Could you please give me some suggestions as to why this happens and how can I rectify it?
Thanks in advance

Hi Anuj,
First, this sounds like a very cool application. What are you measuring? Is it in vivo?
I believe that I see what you are referring to--is it where your cursor is that you are seeing the "step" problem? Also, could you give us a little more information aboutwhat type of data we are looking at? Is this some sort of image analysis data?
In terms of code structure, due to the way that LabVIEW handles image data types (it is essentially a pointer to the data instead of the data itself), I wouldn't recommend passing an image via a queue.
So, please let me know a bit more about what type of data we are looking at, and what your code looks like, and I'll be happy to help.

Pixelated images (with High Quality Display turned on)

Here's my problem: The images look sharp on the internet, but when I download them, place them in Indesign and print them, the look pixelated!
Take this one for example: http://media.smashingmagazine.com/images/typefaces/productus.gif
It's resolution is 72 ppi. But when I place it onto the Indesign A4 page (or Letter format for that matter) it occupys almost entire width of the page.
Why is it so? Why is it so big by default without enlarging it? It's kinda logic that a small 72 ppi image stretched across the whole page will appear blurry when printed on 300 dpi printer.
So how can I set the indesign page to 300 ppi/dpi so images with lower restion will appear smaller when placed on the page and - will be printed sharp?

Where can you specify this preference?
And you mean there's a script for InDesign? Wow, it would be cool to get it. So far I solved that problem by recording an Action in Photoshop and than apply it to all the images using Batch command.
Preference is down at the bottom of the File Handling section ... Check the bos to preserve dimensions and a the relinked file will be scaled back to the same size in ID. Uncheck, and the scale percentage will be preserved.
Almost anything is scriptable in ID (but I don't write them). I recall a script that was posted a year or two ago that would allow you to select an image and type a desired effective resolution into a dialog. The image would get scaled to reach that effective ppi. Your batch action in Photoshop is fine, and useful if you want to palce everything at 100%, but it isn't required to change the resolution in Photshop to achieve what you want. Scaling in ID is exactly the same thing as changing the resolution without resampling in Photoshop. No pixels are added, removed or altered -- only their dispalyed size is changed. If you want a script to set all images to 300 ppi effective resolution, you should probably pay a visit to the scripting forum.

PCI-1422 Windows7 32bit Problems

I have a legacy program that I am trying to port from WindowsXP to 32bit version of Windows7. This program is based on the PCI-1422 frame grabber.
For historical purposes, I have to use NI-IMAQ version 2.5.3, which installs version 2.0.3.17 of NI-MAX
From a clean build of Win7 x32, I can install NI software, and the old application which creates correct camera definition files.
When I add the frame grabber card, Windows device manager is happy... the card is correctly identified and seems to use driver files which match the old WinXP install.
When I look at the card with NI-MAX, the camera correctly appears in the configuration list. If I highlight Channel 0 device and run 'Diagnostic' all tests seem to pass correctly. (Again the displayed output matches the results from the same operation on the old WinXP box)
However if I try to 'Snap' or 'Grab' a frame, I get the following error box: Title = 'Acquisition Error'   and there is NO TEXT in the error description, only a yellow ! warning icon.
(The legacy program performs all controlling functions via two other PCI cards, but halts when trying to grab a frame as well. The above behavior can be seen with or without these additional PCI cards)
I have tried both installing and executing the EXE files with or without 'Run as Admin' and/or 'WinXP SP3 compatibility mode'. In some cases, the available camera list disappears, but nothing I have done has been succesful at grabbing a frame from the camera.
Any suggestions about compatibility and/or why the error box is missing all text?
Thanks in advance,
Jim

Good questions...
I have been asked to 'upgrade' a commercial system that was developed 10 years ago. The system works currently... an XP based system with old frame grabber.   I was asked if I could upgrade the PC, because of concerns of PC failure with a 10 yr old box. We found a new motherboard that supports the necesary 3 PCI slots for frame grabber, and newer CPU of course.
The question remains however, can we migrate to Win7, or...   do we try to install WinXP on the new PC hardware, with the older interface cards. To add to the difficulties, the original company than produced the software is no longer in business. Fortunately I have remained in contact with some of the developers that are giving me some support, but they haven't supported the product for years either.
The basic issue remains... hardware and software that worked on XP, has been migrated. The devices appear in some sense to be detected correctly. But the critical important issue, grabbing a frame from the camear, fails. What can be done?

Failing to detect NI PCI 1422

I have been experiencing a unique problem with the NI PCI 1422 board. After the first install, everything runs fine. However, after some period of operation, errors appear. Then if the board is ever physically removed from the PC, it will never be detected again.
I am running Windows 2000 Pro, on a AMD XP2100+ with 512Mb PC2700 DDR, and have tried several different motherboards. When you replace the motherboard, the card will be detected but only the first time the system is booted up. From then on it is non-existent. I have tried reinstalling everything, flashing the bios, reinstalling from a drive image where it works etc.
I have built an identical system that works fine. I am fairly sure the framegrabber is not faulty, as I have tr
ied replacing that also (to no avail).
Anyone got any suggestions?

What do you mean not detected? Is it not detected in the Windows Device Manager or in MAX? If it is not detected in Device Manager then you should check that computer BIOS and make sure PnP is enabled and PCI Bus Mastering as well. If it is not detected in MAX try hitting F5 (refresh).
What version of the driver do you have? I suggest you have the latest one, 2.5.5.
If Device Manager does recognizes the board you may want to uninstall it from there and then click the refresh button inside Device Manager as well. And see if that recognizes the hardware.

Which digital camera is suitable for the pci-1422

when i purchase a digital cam for PCI-1422 , what should i focus on, for example: Resolution, interface, depth of color or etc??
How to classify the a digital cam and how to identify which is suitable for PCI-1422??
Does anybody have recommandation for me!!??
thanx!!!

There are a lot of digital cameras that work well with the PCI-1422.
Selecting the proper camera depends more on your application than the PCI-1422. You need to look at resolution and frame rate, along with bit depth, color or B&W, etc.
You will also need to select a lens that matches your application. You might just need a fixed focal length, or you might need a zoom, a telecentric lens, or other possibilities.
I would recommend discussing your application with Robert Eastlund of Graftek Imaging (800) 441-2118. He will be able to help you select the proper camera and lens for your application.

How to get a .tif image with n different colors?

Hi..i want to know how can i get a .tif image colored by some colors. I want to do something like this:
if(tifImage.pixel < 0.1) {
tifImage.pixel = yellow;

          JAI.create("filestore",tiledImage,output,"TIFF");
Thanks

I tried that. When I open one image and set the exposure, then go to open the second image, nothing happens. I then saved one image as a psd file, then it would let me open the raw file a second time. When I had both open on the same screen and dragged the layer from one into another image, the layer size ended up being different than the other file. It was shifted down and to the left. I need these images to be pixel locked, and the user experience I went through did not allow me to do this.
I also do not see a way to copy/paste layers between files.

How can I access the control lines of a PCI-1422 from within C++?

I would like to know how the control lines of a PCI-1422 can be accessed (set) programmatically from within C++ (MS VC++7, Windows XP). A flat panel sensor connected to the PCI-1422 needs the control lines to switch on features like binning which I want to use.
Unfortunately I was unable to identify an appropriate command in the IMAQ documentation. Does anyone have experiences with this?
Thank you very much in advance!

Kluas,
The control lines are not exposed through any API. The control lines are run by the driver based on the instructions in the camera files. If the cammera file supports the binning functionality of your camera then you should be able to set the attributes such that the board runs the control lines approriately.
Hope this helps,

How do I select an image with motion blur so that I can put it onto a different background ?

How do I overlay a image with motion blur on a white background (like the first image) onto a different background (to look like the second image)? any help would be greatly appreciated, many thanks ,ed

I’m afraid you may have bitten off more than you might want to chew.
The resulting pixels of an in-camera-blur combine information about the color/brightness of back- and foreground (edit: the result of surface properties and lighting conditions) with motion (basically transparency for this task) in such a way that it seems exceedingly difficult (maybe even improssible) to isolate the foreground in a »pure« form.
One may get a halfway decent mask (as the backgound is at least almost uniform and brighter than the foreground elements) but you may have to manually decontaminate the transparent areas, otherwise the masked object in front of a dark background would have a bright edge.

PCI 1422. Grab an image with 1 pixel height.
