How can I continually update the UI Axes in App Designer to display images from a CMOS camera?

10 views (last 30 days)
I would like to create a video feed in the UI Axes in App Designer. At the moment, I am updating the CData of the figure, though I am having large lag times. The code that I am using runs quickly--in about 100ms--but the image on the UI Axes updates approximately every two seconds. Preferably, the video feed would run parallel so that I can also interact with my GUI simultaneously. Is there a way to use the UI Axes to run this type of figure?

it works in app designer
you can use global var if you want to use the object camera in another function
global cam
im=image(zeros(340,340,3),'Parent',app.UIAxes);
preview(cam,im);
setappdata(app.UIAxes, 'cam', cam);
