bug_camera_open

int bug_camera_open(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

bug_camera_open_default

int bug_camera_open_default()

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

Returns:

0 if open was successful

bug_camera_close

int bug_camera_close()

Closes the camera - allowing other processes to access it.

Returns:

0 if open was successful

bug_camera_start

int bug_camera_start()

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

Returns:

0 if start was successful

bug_camera_stop

int bug_camera_stop()

Stop acquiring frames.

Returns:

0 if stop was successful.

bug_camera_grab_preview

boolean bug_camera_grab_preview(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 bug_camera_open

Returns:

true if grab succeeded

bug_camera_grab_full

byte[] bug_camera_grab_full()

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

Returns:
