* <p>When bokeh mode is on, the camera device may override certain control parameters, such as
* reduce frame rate or use face priority scene mode, to achieve best power and quality
* tradeoffs. When turned on, AE, AWB, and AF run in auto modes, and only the mandatory
* stream combinations of LIMITED hardware level are guaranteed.</p>
* <p>For a logical multi-camera, bokeh may be implemented by stereo vision from sub-cameras
* with different field of view. As a result, when bokeh mode is enabled, the camera device
* may override android.scaler.CropRegion, and the field of view will be smaller than when
* bokeh mode is off.</p>
