int	cameraOpenDefault() Calls bug_camera_open with reasonable default values.
int	cameraStart() Start acquiring frames.
int	cameraStop() Stop acquiring frames.
byte[]	grabFull() Grabs a JPEG-encoded full image.
boolean	grabPreview(int[] pixelBuffer) Grabs a raw RGB-encoded preview image.

cameraOpen

int cameraOpen(java.lang.String media_node,
               int slot_num,
               int full_height,
               int full_width,
               int preview_height,
               int preview_width)

Opens a connection with a camera module and configure it.

Parameters:

media_node -

slot_num - the slot number of the camera module to use, or -1 to use the default (if there's only 1)

full_height - height in pixels to capture full images at

full_width - width in pixels to capture full images at

preview_height - height in pixels to capture preview images at

preview_width - width in pixels to capture preview images at

Returns:

0 if open was successful

cameraOpenDefault

int cameraOpenDefault()

Calls bug_camera_open with reasonable default values. (DEFAULT_MEDIA_NODE, -1, 2048, 1536, 320, 240)

Returns:

0 if open was successful

cameraClose

int cameraClose()

Closes the camera - allowing other processes to abug_camera_openccess it.

Returns:

0 if open was successful

cameraStart

int cameraStart()

Start acquiring frames. Must be called before the grab methods may be called.

Returns:

0 if start was successful

cameraStop

int cameraStop()

Stop acquiring frames.

Returns:

0 if stop was successful.

grabPreview

boolean grabPreview(int[] pixelBuffer)

Grabs a raw RGB-encoded preview image. bug_camera_open() and bug_camera_start() must already have been called.

Parameters:

pixelBuffer - array of size preview width * preview height from the call to open(). You can create such a buffer with: BufferedImage image = new BufferedImage(imageWidth, imageHeight, BufferedImage.TYPE_INT_RGB); int [] buf = ((DataBufferInt) image.getRaster().getDataBuffer()).getData();

Returns:

true if grab succeeded

grabFull

byte[] grabFull()

Grabs a JPEG-encoded full image. bug_camera_open() and bug_camera_start() must already have been called.

Returns:
