HTC Desire 上的本机相机参数

我正在 HTC Desire 上开发相机应用程序，并且想了解一些本机 Camera.Parameter 设置。希望这里有人有更多的见解。

当对获得的 Camera.Parameters 对象调用 unflatten() 时，我得到一个包含键值对的长列表。其中一些如下：

sharpness-def=10;
sharpness-max=30;
sharpness-min=0;
sharpness=10;

contrast-min=0;
contrast-max=10;
contrast-def=5;
contrast=5;

brightness-min=0;
brightness-max=6;
brightness-def=3;
brightness=3;

saturation-min=1;
saturation-max=10;
saturation=5;
saturation-def=5;

enable-caf=off;

vertical-view-angle=42.5;
horizontal-view-angle=54.8;

锐度、对比度、亮度和饱和度有最小/最大边界。但我不确定亮度和亮度定义之间的区别。实际上可以通过 API 调用 set(String key, String value) 来设置两者。哪一个具有实际价值，另一个有什么用？

“enable-caf”可能有什么用？

对于垂直视角和水平视角，我总是得到相同的值 - 也许是镜头校正的静态值？

I am developing a camera application on a HTC Desire and wonder about some of the native Camera.Parameter settings. Hopefully someone over here has more insights.

When calling unflatten() on the obtained Camera.Parameters object, I get a long list with key-value pairs. Some of them are the following:

sharpness-def=10;
sharpness-max=30;
sharpness-min=0;
sharpness=10;

contrast-min=0;
contrast-max=10;
contrast-def=5;
contrast=5;

brightness-min=0;
brightness-max=6;
brightness-def=3;
brightness=3;

saturation-min=1;
saturation-max=10;
saturation=5;
saturation-def=5;

enable-caf=off;

vertical-view-angle=42.5;
horizontal-view-angle=54.8;

There are min/max boundaries for sharpness, contrast, brightness and saturation. But I am not sure about the difference between e.g. brightness and brightness-def. It is actually possible to set both with the API call set(String key, String value). Which one holds the actual value and what is the other one for?

What might be "enable-caf" for?

And for vertical-view-angle and horizontal-view-angle I always get the same values - maybe static values for lens correction?
