Constructor Detail

Camera

public Camera()

Default constructor. Defaults to the first camera device returned by a call to getDeviceNameList(). It also defaults to the pre-defined DEFAULT_VIDEO_FORMAT.

Camera

public Camera(java.lang.String deviceName)

Constructs a camera with the passed camera deviceName. This constructor uses the pre-defined DEFAULT_VIDEO_FORMAT as its video format. (See the constructor details for hints on how to use this more robustly!!!)

Parameters:

deviceName - Name of the camera device to use for this camera object. (The most robust way to get a valid deviceName is to make a call to getDeviceNameList and use one of the returned values when calling this constructor.)

Camera

public Camera(javax.media.format.VideoFormat videoFormat)

Constructs a camera with the passed camera deviceName. This constructor uses the first camera that defines this video format. (See the constructor details for hints on how to use this more robustly!!!)

Parameters:

videoFormat - The video format you want this camera to use. (The most robust way to get a valid videoFormat is to make a call to getAllSupportedVideoFormats() and use one of the returned values when calling this constructor.)

Camera

public Camera(java.lang.String deviceName,
              javax.media.format.VideoFormat videoFormat)

Constructs a camera with the passed camera deviceName. (See the constructor details for hints on how to use this more robustly!!!)

Parameters:

deviceName - Name of the camera device to use for this camera object. (The most robust way to get a valid deviceName is to make a call to getDeviceNameList and use one of the returned values when calling this constructor.)

videoFormat - The video format you want this camera to use. (The most robust way to get a valid videoFormat is to make a call to getAllSupportedVideoFormats() and use one of the returned values when calling this constructor.)

Camera

public Camera(java.lang.String deviceName,
              int displayMode,
              boolean showTimes,
              javax.media.format.VideoFormat videoFormat)

Constructs a camera with the passed camera deviceName. (See the constructor details for hints on how to use this more robustly!!!)

Parameters:

deviceName - Name of the camera device to use for this camera object. (The most robust way to get a valid deviceName is to make a call to getDeviceNameList and use one of the returned values when calling this constructor.)

displayMode - The display mode of the camera. DISPLAY_NOTHING - (the default) does not show DISPLAY_ON_EVENT - (used for debug) used in main of this class to show images when requested DISPLAY_ALL_VIDEO - (used for debug) streams the video to a player frame

showTimes - Used purely for debugging purposes, but shows processing times. (If you override processTimes you can use addTimeString and if this is set to true, after every image is processed the time string debug info is printed to the console.)

videoFormat - The video format you want this camera to use. (The most robust way to get a valid videoFormat is to make a call to getAllSupportedVideoFormats() and use one of the returned values when calling this constructor.)

Method Detail

stopWatching

public void stopWatching()

Stops the camera.

startWatching

public void startWatching()

startWatching will initiate image transfer from the camera. It uses the settings that were set from JMStudio, then starts fetching the images. After each image is fetched, processImage() is called. This method returns immediately after the camera is initialized, unlike WatchCamera.startWatching() which doesn't return until the stopWatching() method is called.

open

public void open(javax.media.protocol.DataSource dataSource)

DO NOT use this method!!!! It is for initializing the camera, and is only public because it is inherited

Overrides:

open in class jmapps.ui.PlayerFrame

controllerUpdate

public void controllerUpdate(javax.media.ControllerEvent event)

DO NOT use this method!!! It is for initializing the camera, and is only public because it is inherited. This is where the actual data transfer handler is set for the camera for obtaining the pixel data.

Specified by:

controllerUpdate in interface javax.media.ControllerListener

Overrides:

controllerUpdate in class jmapps.ui.PlayerFrame

main

public static void main(java.lang.String[] args)

Entry point for viewing the camera images without doing any processing on the pixels. Useful for making sure the camera is working.

getImage

public java.awt.Image getImage()

Returns the current image in java.awt.Image format

getImageDimension

public java.awt.Dimension getImageDimension()

Returns the dimesions requested for this watch camera device.

getVideoFormat

public javax.media.format.VideoFormat getVideoFormat()

Returns the video format of this camera device.

getDeviceName

public java.lang.String getDeviceName()

Returns the device name that the object is using.

getShortDeviceName

public java.lang.String getShortDeviceName()

Returns the device name without the "vfw:" prefix.

getObservableImage

public ObservableImage getObservableImage()
