   MODULE  : MFW_CAM

   PURPOSE : This module contains Camera Interface functions.

   HISTORY:

       Nov 29, 2005 REF: MMI-SPR-33833(OMAPS00055207)- x0035544
       MMI making Riviera calls without using proper header files. So added appropriate header files.
       
    	Sept 15, 2005 REF: LOCOSTO-ENH-34257 - xpradipg
	Description: Locosto: MIgration to New LCD APIs
	Solution: Migrated to New APIs by replacing the old driver APIs with
	corresponding New LCD APIs

   	Sep 13, 2005    REF: SPR 33992 xdeepadh	
	Description: Image viewer cannot open file when saved in high quality	
	Solution: The quality factor has been rearranged to support saving	the images within 64KBlimit.

 	Aug 22 2005, xpradipg - LOCOSTO-ENH-31154
 	Description:	Application to test camera
 	Solution:	Implemented the camera application with following functionalities
 			preview, snapshot and image saving.
