As that is primarily about reading video files, you might also need the hints from https://www.mathworks.com/help/vision/examples/face-detection-and-tracking-using-live-video-acquisition.html on how to take pictures from a live camera.

If I recall correctly, it is possible to hack the windows created by preview() for webcam, but I seem to remember that I found if you did that, then when you closed the left-over window, you would get a video crash.

MATLAB: Convert live colour video into gray scale video

Hi,

You can modify your code like this to get the desired results.

CODE :

imaqreset; 
%warning('off','all'); %.... diable warining msg ...; 
vid = videoinput('winvideo',1, 'YUY2_640x480'); 
set(vid, 'FramesPerTrigger', Inf); 
set(vid, 'ReturnedColorspace', 'rgb'); 
% vid.FrameRate =30; 
vid.FrameGrabInterval = 1; % distance between captured frames 
start(vid) 
aviObject = VideoWriter('myVideo.avi'); % Create a new AVI file 
open(aviObject); 
for iFrame = 1:50 % Capture 100 frames 
% ... 

% You would capture a single image I from your webcam here 
% ... 
I=getsnapshot(vid); 
%changes made here
grayimg = rgb2gray(I); % Convert rgb image to grayscale img 
%imshow(I); 
F = im2frame(grayimg); % Convert grayimg to a movie frame 
writeVideo(aviObject,F); % Add the frame to the AVI file 
end 
close(aviObject); % Close the AVI file 
stop(vid);
