开发专栏：我的项目实战

需要

  1. 屏幕分辨率 1920 x 1080；
  2. 白平衡、解冻、主动背光、主动光源等性能；’
  2. 拍照性能，可设置拍照门路（U 盘，SD 卡，内置存储）；
  3. 录像性能，可设置录像门路（U 盘，SD 卡，内置存储）；
  4. 亮度调整，摄像头光源亮度调整；
  5. 物理按键，包含拍照、录像、上下左右、菜单、默认亮度、抉择等等；
  6. 定制开机界面；
  7. 照片、视频九宫格浏览控件；
  8. 照片浏览器；
  9. 视频播放器；
  10. 可查看照片、视频同时反对按键对照片和视频的操作；
  11. 对存储控件的资源浏览器控件’，并可对其复制、粘贴、删除等操作；
  12. 设置工夫日期，仿苹果滑动成果；
  13. 其余各种定制控件；

留神

  受限于老本（计划整体老本，较同行业最低），一直压缩的老本，导致该产品的呈现要害难点，其在于 fpga 上的仿 arm 跑 linux 的芯片性能等同于 2011 年的 arm 程度，通过 fpga+arm+qt 三方的代码优化和内存优化。’

物理按键

  须要模仿物理按键，在整个零碎运行时对所有按键进行对应的业务解决，按键如下图：
