The following code displays a black image instead of the expected grabbed frame.

b = imread('ngc6543a.jpg');
imshow(b)
currF = getframe(gcf)
image(currF.cdata)

currF.cdata is an all zero matrix.

Did anyone have/solved this problem?

Thanks

Which MATLAB release are you using?

I also have this issue on SUSE Enterprise 11 and R2011b.
