Hello! I am running a system with GigE camera with NI framegrabber in continuous acquisition mode - in which I change some attributes every now and then. So far I have been using following scheme to assert I am getting correct image after attribute change: change attribute read "Last buffer number" property -> n run IMAQdx get image.vi set to "buffer' and parameter n+2 (+2 being due to the fact that i assumed attribute change arrives to camere during running exposure that will be unaffected by attribute change - hence i needed to discard "next" buffer) Unfor

Hello, Research purpose, I am using Imagining Source (DMK 33Ux249) camera to capture the laser beam. I am trying to write a code for auto exposure according to power level of laser beam. I used Vision acquistion for capturing live video image and tried to open the front panel of the vision acquistion. But, I couldn't figure out how to set the exposure level automatically. Basically whole task is, 1. Capturing live image 2. set the exposure time according to laser beam profile 3. Remember the exposure the time and set again according to next frame or beam profile.

Hi to all. I would like to get the number of white pixels in an image (so get the white area). I see histogram.vi but I do not know how to do that. Any help? Thanks a lot!

I would like to know if there is a parameter in line scan camera which allow me to control time trigger along NI MAX or labview with imaqdx. I mean, I would like to triggering camera during 100ms which specific shutter and specific line/sec. And if I change shutter or line/sec the time trigger keep being the same (100ms) I don't know if this is possible with some parameter of line scan camera. Thanks a lot.

Hello to all. First of all thanks a lot for reading this post and being able to help. I have noticed the next problem: My application has a camera, this camera takes images (snap mode) and application process them (detect some edges in the image). It works fine. But when I make the Display bigger my application takes longer to process images (and for me that is crucial). I think that this happens because my application in this case has to process a bigger image (bigger display = bigger image??) So maybe if My camera takes images with lower resolution I solve the proble

Hello to all. I am using NI MAX to get images from a camera (snao mode and hardware trigger). The camera is a basler 1300-30gm. The problem is the next: My camera snaps 4 images (1 image each 40ms). In pylon viewer (camera oficcial software) I can see the four images correctly. The problem is that when I am trying to see the 4 images in NI MAX sometime the camera can not take the 4th image... like there is no time to take the 4 image (or process it to visualize in NI MAX). So maybe there is a configuration parameter in NI MAX to solve this. Any ideas? Ho

Hello to all. I have an image and a ROI. I would like to get the minimun distance between the first edge and the last edge in horizontal position. See image attached. If every edges found are in color yellow I would like to get the distance between edges in red (minimun distance from last edge to last edge in horizontal direction. I have tried to use "IMAQ Clamp Horizontal Min VI" but this VI does't the option "from first to last edge" and the only way to get what I want is to play with contrast but it is not work for some of my images. So is there any way to get what
