+/**
+ * CameraHardwareInterface.h defines the interface to the
+ * camera hardware abstraction layer, used for setting and getting
+ * parameters, live previewing, and taking pictures.
+ *
+ * It is a referenced counted interface with RefBase as its base class.
+ * CameraService calls openCameraHardware() to retrieve a strong pointer to the
+ * instance of this interface and may be called multiple times. The
+ * following steps describe a typical sequence:
+ *
+ * -# After CameraService calls openCameraHardware(), getParameters() and
+ * setParameters() are used to initialize the camera instance.
+ * CameraService calls getPreviewHeap() to establish access to the
+ * preview heap so it can be registered with SurfaceFlinger for
+ * efficient display updating while in preview mode.
+ * -# startPreview() is called, which is passed a preview_callback()
+ * function and a user parameter. The camera instance then periodically
+ * calls preview_callback() each time a new preview frame is available.
+ * The callback routine has two parameters: the first is a pointer to
+ * the IMemory containing the frame and the second a user parameter. If
+ * the preview_callback code needs to use this memory after returning,
+ * it must copy the data.
+ *
+ * Prior to taking a picture, CameraService calls autofocus() with
+ * autofocus_callback() and a user parameter. When auto focusing has
+ * completed, the camera instance calls autofocus_callback(), which informs
+ * the application whether focusing was successful. The camera instance
+ * only calls autofocus_callback() once and it is up to the application to
+ * call autoFocus() again if refocusing is desired.
+ *
+ * CameraService calls takePicture() to request the camera instance take a
+ * picture. This method has two callbacks: raw_callback() and jpeg_callback().
+ * When the raw image is available, raw_callback() is called with a pointer
+ * to the IMemory containing the raw image. When the jpeg image is available,
+ * jpeg_callback() is called with a pointer to the IMemory containing the
+ * jpeg image. As with preview_callback(), the memory must be copied if it's
+ * needed after returning.
