#include <twl/camera.h>
BOOL CAMERA_IsBusy( void );
None.
Returns TRUE
if the camera is capturing image data
Returns TRUE
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 CAMERA_Start
or CAMERA_StartCapture
function until the start of the camera V-Blank that follows a call to the CAMERA_Stop
or CAMERA_StopCapture
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.
Note: If capturing is stopped while the camera is in standby mode, this function continues to return TRUE
even though image data is not being obtained.
The following functions cannot be used while this function returns TRUE
.
CAMERA_SetTrimmingParamsCenter
CAMERA_SetTrimmingParams
CAMERA_SetTrimming
CAMERA_SetOutputFormat
CAMERA_SetTransferLines
CAMERA_Start
