+ User NOTES
+1. How to use this driver:
+--------------------------
+ - This driver is used to drive the camera.
+ - The OV9655 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()
