摘　　要：为解决在Windows CE系统启动过程中的黑屏现象,提出了一种基于Windows CE 6.0下Bootloader中添加启动画面的设计方法,避免在系统启动时间内显示屏幕上无画面输出,减小了在实际产品启动过程中的时延造成客户的视觉等待而降低客户体验的问题。该方法是在Bootloader中LCD控制器初始化后加入一段完整启动输出画面的代码,同时,利用线性插值法对图像进行优化处理。与传统的启动画面的实现相比较,在保证图像清晰的同时,该设计方法降低了对图片大小的限制,实验结果表明,线性插值算法对于缩放比例较小的情况是完全可以接受的。To resolve the phenomenon that there was black-screen during system booting process, this paper proposed a method of adding a booting LOGO into Bootloader based on Windows CE operation system. It avoided no figure outputting during system booting,and eliminated the startup delay of actual product during the system booting process which caused the vision waiting of customers and reduced customer experience. The method was to add the code of picture after the LCD controller was initialized in the Bootloader, also, it used a linear interpolation to optimize the image. Compared to the traditional system booting LOGO, this method ensured the image was clear as well as reduced the image size. The results suggest that the linear interpolation for the smaller scaling is perfectly acceptable.
