Starts getting image data from the next frame after this function was called (at the end of the camera V-Blank). For this reason, the actual sending of data to the buffer set by functions such as <a href="CAMERA_DmaRecvAsync.html"><CODE>CAMERA_DmaRecvAsync</CODE></a> does not begin until after the next camera V-Blank.<br>Note that the camera V-Blank differs from the LCD (GX) V-Blank. <BR><BR>This function starts saving image data to the line buffer for the active camera.

Consequently, note that if camera settings are changed while capturing, the application may not be able to get an updated image (an image with changes applied) at the time the application intended. 26</P> 27 28<H2>See Also</H2> 29<P><A href="CAMERA_StopCapture.html"><CODE>CAMERA_StopCapture</CODE></A><BR> <A href="CAMERA_I2CActivate.html"><CODE>CAMERA_I2CActivate</CODE></A><BR> <a href="CAMERA_DmaRecvAsync.html"><CODE>CAMERA_DmaRecvAsync</CODE></a></P> 30<H2>Revision History</H2> 31<P> 322009/03/25 Added a note on changes to camera settings during capture operations. <br>2008/11/21 Added a note on the timing at which data transmissions actually start. <br>2007/10/22 Added <B>Description</B>. <BR>2007/10/02 Initial version.</P> 33<hr><p>CONFIDENTIAL</p></body> 34</HTML> 35
