Camera.Parameters

public class Camera.Parameters
extends Object

java.lang.Object
↳	android.hardware.Camera.Parameters

This class was deprecated in API level 21.
We recommend using the new android.hardware.camera2 API for new applications.

Camera service settings.

To make camera parameters take effect, applications have to call setParameters(Camera.Parameters). For example, after setWhiteBalance(String) is called, white balance is not actually changed until setParameters(Camera.Parameters) is called with the changed parameters object.

让相机参数生效,利用程序必须调用setParameters(Camera.Parameters)。例如,在setWhiteBalance(String),白平衡实际上其实不是改变直到setParameters(Camera.Parameters)更改的参数对象。

Different devices may have different camera capabilities, such as picture size or flash modes. The application should query the camera capabilities before setting parameters. For example, the application should call getSupportedColorEffects() before calling setColorEffect(String). If the camera does not support color effects, getSupportedColorEffects() will return null.

不同的装备有不同的相机功能,如图象大小或闪光模式。利用程序之前应当查询相机功能设置参数。例如,利用程序应当调用getSupportedColorEffects()调用之前setColorEffect(String)。如果相机不支持色彩效果,getSupportedColorEffects()将返回null。
