Answer 1

您必須設置參數在CaptureRequest.Builder，那裏你可以將所有你想要的效果：

int colorEffectValue = 
//Choose your effect: 
//CaptureRequest.CONTROL_EFFECT_MODE_MONO 
//CaptureRequest.CONTROL_EFFECT_MODE_NEGATIVE 
//CaptureRequest.CONTROL_EFFECT_MODE_SOLARIZE 
//CaptureRequest.CONTROL_EFFECT_MODE_SEPIA 
//CaptureRequest.CONTROL_EFFECT_MODE_POSTERIZE 
//CaptureRequest.CONTROL_EFFECT_MODE_WHITEBOARD 
//CaptureRequest.CONTROL_EFFECT_MODE_BLACKBOARD 
//etc, you can find all modes in CameraMetadata 
youtCaptureBuilder.set(CaptureRequest.CONTROL_EFFECT_MODE, colorEffectValue);
