红胖子(红模仿)的博文大全：开发技术集合（包含Qt实用技术、树莓派、三维、OpenCV、OpenGL、ffmpeg、OSG、单片机、软硬结合等等）持续更新中…（点击传送门）
1. 屏幕分辨率1920 x 1080；
2. 白平衡、冻结、自动背光、自动光源等功能；’
2. 拍照功能，可设置拍照路径（U盘，SD卡，内置存储）；
3. 录像功能，可设置录像路径（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，包括拍照、录像、上下左右、菜单、默认亮度、选择等等；
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、视频同时支持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. 设置时间日期，仿苹果滑动效果；
13. 其他各种定制控件；
受限于成本（方案整体成本，较同行业最低），不断压缩的成本，导致该产品的出现关键难点，其在于fpga上的仿arm跑linux的芯片性能等同于2011年的arm水平，经过fpga+arm+qt三方的代码优化和内存优化。’
软件界面
需要模拟物理按键，在整个系统运行时对所有按键进行对应的业务处理，按键如下图：
