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.

讓相機參數生效,利用程序必須調用setParameters(Camera.Parameters)。例如,在setWhiteBalance(String),白平衡實際上其實不是改變直到setParameters(Camera.Parameters)更改的參數對象。

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.

不同的裝備有不同的相機功能,如圖象大小或閃光模式。利用程序之前應當查詢相機功能設置參數。例如,利用程序應當調用getSupportedColorEffects()調用之前setColorEffect(String)。如果相機不支持色彩效果,getSupportedColorEffects()將返回null。
