NoiseReductionMode
Fields
| Name | Value | Description |
|---|---|---|
| Off | 0 | No noise reduction is applied. Android reference for Portions of this page are modifications based on work created and shared by the Android Open Source Project and used according to terms described in the Creative Commons 2.5 Attribution License. |
| Fast | 1 | Noise reduction is applied without reducing frame rate relative to sensor output. It may be the same as OFF if noise reduction will reduce frame rate relative to sensor.

| HighQuality | 2 | High-quality noise reduction is applied, at the cost of possibly reduced frame rate relative to sensor output.

| Minimal | 3 | MINIMAL noise reduction is applied without reducing frame rate relative to sensor output.

| ZeroShutterLag | 4 | Noise reduction is applied at different levels for different output streams, based on resolution. Streams at maximum recording resolution (see CameraDevice.createCaptureSession(SessionConfiguration)) or below have noise reduction applied, while higher-resolution streams have MINIMAL (if supported) or no noise reduction applied (if MINIMAL is not supported.) The degree of noise reduction for low-resolution streams is tuned so that frame rate is not impacted, and the quality is equal to or better than FAST (since it is only applied to lower-resolution outputs, quality may improve from FAST). This mode is intended to be used by applications operating in a zero-shutter-lag mode with YUV or PRIVATE reprocessing, where the application continuously captures high-resolution intermediate buffers into a circular buffer, from which a final image is produced via reprocessing when a user takes a picture. For such a use case, the high-resolution buffers must not have noise reduction applied to maximize efficiency of preview and to avoid over-applying noise filtering when reprocessing, while low-resolution buffers (used for recording or preview, generally) need noise reduction applied for reasonable preview quality. This mode is guaranteed to be supported by devices that support either the YUV_REPROCESSING or PRIVATE_REPROCESSING capabilities (android.request.availableCapabilities lists either of those capabilities) and it will be the default mode for CAMERA3_TEMPLATE_ZERO_SHUTTER_LAG template.
