Function Documentation

int CAMGet

(

BYTE *

buf

)

Retrieve a camera frame into the provided buffer.

Parameters

[in]

buf

The buffer to copy the camera frame into. The supplied buffer must be large enough to acommodate the size of the image, as defined by the camera mode.

Returns

Nonzero on success, zero on failure. On failure, the contents of buf is undefined.

Retrieves the current camera frame and copies it into the supplied buffer. CAMInit must have been called previously.

int CAMGetGray

(

BYTE *

buf

)

Grabs a gray image off the camera.

Parameters

the	byte stream to store the image data, data in Gray format

Returns

0 iff initialised correctly, otherwise 1

int CAMGetMode

(

void

)

Retrieves the current camera mode.

Returns

The camera mode, or CAM_NONE on error.

CAMInit must have been called previously.

int CAMRelease

(

void

)

Stops and releases all camera structures.

Returns

Nonzero on success, zero on failure.

Releases all allocated memory and stops video capture.

int CAMSetMode

(

int

mode

)

Set the camera mode (e.g. format and resolution).

Parameters

[in]

mode

The camera mode to be set to

Returns

Nonzero on success, zero on failure.

Sets the camera mode. CAMInit must have been called previously.
