This needs a bit more clarification, do you want simulink to actuate a usb webcam snapshot and then display in simulink? Or do you just need to display a snapshot image in simulink. For the latter, you can try displaying the image in an annotation, let me know if this helps.

I designed an algorithm that needs to get a image matrix in order to work. I want to turn on a camera in real time and after a few seconds take a snapshot and put it into the Matlab function.. I try with the block "from video deveice" and I don't know what to do now..

Hi Dekel Mashiah,
I understand that you are trying to capture images from a webcam and use that in a MATLAB function. You can try the two possible steps:
  • Use can capture the images through webcam directly to MATLAB using the Webcam Image Acquisition using the function snapshot. For the same you can refer the following documentations:
Webcam Image Acquisition: Webcam Image Acquisition - MATLAB & Simulink (mathworks.com)
Snapshot function : Acquire single image frame from a webcam - MATLAB snapshot (mathworks.com)
Hope the above provided information helps you!!
