USB摄像头之130w像素 OV9655配置

为了usb2.0采集达到足够的速率，不得不将采用raw格式输出。

不得不说，这样配置任然不是太完美，其中行像素高达2560，列像素1024，帧率只能达到7.5fps，还得继续努力

上位机采集还必须做如下几个处理：

像素设置为2560*1024

显示的时候必须宽度压缩一倍。

VGA输出则：

其中行像素高达1280，列像素480，帧率只能达到29.5fps，还得继续努力

上位机采集还必须做如下几个处理：

像素设置为1280*480

显示的时候必须宽度压缩一倍。

raw格式：BGGR  而QVGA则是GRBG

显示为：640*480   VGA已达到规格书要求
