                                   User NOTES
1. How to use this driver:
--------------------------
   - This driver is used to drive the camera.
   - The S5K5CAG component driver MUST be included with this driver.

2. Driver description:
---------------------
  + Initialization steps:
     o Initialize the camera using the BSP_CAMERA_Init() function.
     o Start the camera capture/snapshot using the CAMERA_Start() function.
     o Suspend, resume or stop the camera capture using the following functions:
      - BSP_CAMERA_Suspend()
      - BSP_CAMERA_Resume()
      - BSP_CAMERA_Stop()

  + Options
     o Increase or decrease on the fly the brightness and/or contrast
       using the following function:
       - BSP_CAMERA_ContrastBrightnessConfig
     o Add a special effect on the fly using the following functions:
       - BSP_CAMERA_BlackWhiteConfig()
       - BSP_CAMERA_ColorEffectConfig()
