succesive onPreviewFrame byte[]
<p>I am capturing the onPreviewFrame in a byte[] and then saving this to compare with the next captured frame.   Although the camera is pointed to an area with no change happening and I can see on the display that there is no change succesive frames element by elemnet are different.  Any suggestion why this should be so?   Also I only want the grayscale and I understand that the first height * width bytes are grayscale data, is this correct></p>
