I am using the Image Acquisition Toolbox to create a simple interactive GUI that should allow the user to preview the image and dynamically adjust the brightness of the video feed.
I'm using a slider to adjust the value of brightness between(-64 to 64), code looks like this:
vid = videoinput('winvideo',1);
src = getselectedsource(vid);
preview(vid);
bri = get(handles.BrightnessSlider,'Value');
if(bri > -65 || bri < 65 )
stoppreview(vid);
src.Brightness = bri;
preview(vid);
end
Problem here is that brightness isn't changing when I move the slider, the value on slider does change.
Please help me solving this error. Thanks in advance.
