Detailed Description

This file includes the driver for Camera modules mounted on STM32L4R9I_DISCOVERY board.

Author:

MCD Application Team

    How to use this driver:
    ------------------------
     - This driver is used to drive the camera.
     - The OV9655 component driver MUST be included with this driver.

    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()
