Hello, I am trying to connect a Sony FCB MA 130 camera with matlab to superimpose a circle. Here there is the code:
% Create a video input object.
vid = videoinput('macvideo',2);
% Create a figure window. This example turns off the default
% toolbar, menubar, and figure numbering.
'Menubar', 'none',...
'Name','My Preview Window');
% Create the image object in which you want to display
% the video preview data. Make the size of the image
% object match the dimensions of the video frames.
vidRes = vid.VideoResolution;
nBands = vid.NumberOfBands;
hImage = image( ones(vidRes(2), vidRes(1), nBands) );
hold on
viscircles([1920/2 1080/2],10)
preview(vid, hImage);
I'd like to change some parameters, such that brightness, focus and so on, but if I try to execute the following command:
src = getselectedsource(vid);
No parameters are included in the answer;
Could someone help me?
