CAMERA_IsBusy

Syntax

#include <twl/camera.h>

BOOL CAMERA_IsBusy( void );

Arguments

None.

Return Values

Returns TRUE if the camera is capturing image data

Description

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
