Fields
| Name | Value | Description |
|---|---|---|
| Off | 0 | No edge enhancement 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 | Apply edge enhancement at a quality level that does not slow down frame rate relative to sensor output. It may be the same as OFF if edge enhancement will slow down frame rate relative to sensor.

| HighQuality | 2 | Apply high-quality edge enhancement, at a cost of possibly reduced output frame rate.

| ZeroShutterLag | 3 | Edge enhancement is applied at different levels for different output streams, based on resolution. Streams at maximum recording resolution (see CameraDevice.createCaptureSession(SessionConfiguration)) or below have edge enhancement applied, while higher-resolution streams have no edge enhancement applied. The level of edge enhancement 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 edge enhancement applied to maximize efficiency of preview and to avoid double-applying enhancement when reprocessed, while low-resolution buffers (used for recording or preview, generally) need edge enhancement 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.
