rgbImage = getsnapshot(videoObject);
imwrite(rgbImage, fullFileName);

if meanGL < 20 % or whatever.
warningMessage = sprintf('Something is wrong.\nThe image is too dark.\nThe mean intensity is
only %.1f gray levels', meanGL);
uiwait(warndlg(warningMessage));

It looks like you might have a simple typo. Did you want to use the function mean2() rather than meann2()?
