26<P>
27Returns <CODE>TRUE</CODE> if the camera is capturing image data. Specifically, the image capture state spans from the end of the camera V-Blank that follows a call to the <A href="CAMERA_Start.html"><code>CAMERA_Start</code></A> or <A href="CAMERA_StartCapture.html"><code>CAMERA_StartCapture</code></A> function until the start of the camera V-Blank that follows a call to the <A href="CAMERA_Stop.html"><code>CAMERA_Stop</code></A> or <A href="CAMERA_StopCapture.html"><code>CAMERA_StopCapture</code></A> function. If the aforementioned functions are called during a camera V-Blank, the state is updated during that V-Blank instead of the next one.<BR><BR><FONT color="red"><B>Note:</B></FONT> If capturing is stopped while the camera is in standby mode, this function continues to return <CODE>TRUE</CODE> even though image data is not being obtained.<BR><BR> The following functions cannot be used while this function returns <CODE>TRUE</CODE>.<BR> <A href="CAMERA_SetTrimmingParamsCenter.html"><CODE>CAMERA_SetTrimmingParamsCenter</CODE></A><BR> <A href="CAMERA_SetTrimmingParams.html"><CODE>CAMERA_SetTrimmingParams</CODE></A><BR> <A href="CAMERA_SetTrimming.html"><CODE>CAMERA_SetTrimming</CODE></A><BR> <A href="CAMERA_SetOutputFormat.html"><CODE>CAMERA_SetOutputFormat</CODE></A><BR> <A href="CAMERA_SetTransferLines.html"><CODE>CAMERA_SetTransferLines</CODE></A>
