Design of Touch-LCD Interface in Image Focusing System Based on OMAP Processor

GUO Tong-jian,LIN Zhao-hua,DU Bi-xiu(Changchun Institute of Optics,Fine Mechanics and Physics,Chinese Academy of Sciences,Changchun 130033,China)  
According to the actual requirements,a scheme of image focusing system based on OMAP processor was proposed,and the hardware design of interface with touch-LCD was introduced in detail.Then,the relevant Linux drivers were analyzed and two key problems in the application,the transform of image resolution and the form of touch-dot window,were discussed.Therefore,the inputting image data and focusing window could be displayed on the LCD proportionally.When the auto-selecting focusing window didn't meet the needs,touch screen could be used to readjust it.As a result,the quick manual selection and adjustment of focusing window was implemented,which met the special need of image focusing system in special field.
