是本人VGA的摄像头的设定，可以运行，左右向反，可是，图像太大了，不知道怎么调节焦距，让图像变得小一点，嘿嘿，本人很急，请做过的不吝赐教

lixue51

调焦距不是这些寄存器设定的，应该是厂家设定的    可以调整分辨率

烽火寒轩

我要的效果是不仅分辨率要低，640×480的VGA模式，从中间裁减出一个240×320的图片，然后对这个240×320的图像进行处理，这个分辨率都是确定的，不能改。现在就是不想让显示的图片太大了，难道寄存器不能调节焦距吗，如果寄存器不能调节焦距，请问硬件方面我应该怎么调节啊，还有，谁能不能发给我ov9650中文的datasheet，或者发点寄存器的中文资料，还有就是简写的意思，例如 AEC：自动增益控制。等等。我自己正在些寄存器的中文解释，等我写完了，大家给我修改修改，这里发送一部分写完的，爱，菜鸟学习中，谢谢所有人

摄像头模块的焦距一般的模块是不支持进行调整的，厂家没有提供对应的接口，而且有些模块，在硬件与结构、光学设计上就没有支持调整焦距的。

楼主看看0V9650的技术手册。

99012606

你要得到320*240大小的图片，这样在LCD显示上是可以实现的，他的画面是边界大小是320*240的 但是他的大小还是640*480的 因为分辨率是640*480的

至于中文手册 我也没有 我也看的英文的，一些寄存器 我也不是很懂

FIH

顶下！
