结合图像调焦系统的实际应用需求,提出一种基于OMAP(Open Multimedia Application Plant)处理器的图像调焦系统方案,给出了处理器与触摸显示屏的接口硬件设计,分析了在Linux系统下的接口驱动开发,讨论了实际应用中存在的图像分辨率变换及触点窗口形成两个关键问题,将输入的图像数据及对焦窗口成比例显示在液晶屏上.在自动选择的对焦窗口不满足要求时,使用触摸屏来重新调整对焦窗口,从而实现人工参与对焦窗口的快速选择及调整,满足了特定领域对图像调焦系统的特殊要求.

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 adjust-ment of focusing window was implemented, which met the special need of image focusing system in special field.
