Data:

CAMERA_FEATURE_FBM: Indicates that whether the camera supports queries from the camera_can _feature() and camera_has_feature() functions.

CAMERA_FEATURE_PHOTO: Indicates that it is possible to take photos (still images).

CAMERA_FEATURE_VIDEO: Indicates that it is possible to encode video.

CAMERA_FEATURE_PHOTOZOOM: Indicates zoom is available for shooting photos.

CAMERA_FEATURE_VIDEOZOOM: Indicates that zoom is available for recording video.

CAMERA_FEATURE_ZSL: Indicates that zero-shutter lag is available.

CAMERA_FEATURE_BURST

Indicates that burst mode is available for taking multiple photos consecutively.

When CAMERA_FEATURE_BURST is available, but CAMERA_FEATURE_CONTINUOUSBURST isn't, then only the camera_take_burst() function can be used. The camera_start_burst() function will not work.

CAMERA_FEATURE_EVBRACKETING: Indicates that exposure bracketing is available in burst capture mode.; EV represents Exposure value, which is a combination of a number camera functions such as shutter speed, aperture, and gain.

CAMERA_FEATURE_FLASH: Indicates that flash is available.

CAMERA_FEATURE_VIDEOLIGHT: Indicates that an on-board light source is available for use with video capture.

CAMERA_FEATURE_PREVIEWISVIDEO: Indicates that there is no standalone video buffer stream available.; Preview buffers are used for both viewfinder and video encoding.

CAMERA_FEATURE_AUTOFOCUS: Indicates that autofocus is available.

CAMERA_FEATURE_MANUALFOCUS: Indicates that manual focus is available.

CAMERA_FEATURE_REGIONFOCUS: Indicates that it is possible to focus on a specific region in the photo.

CAMERA_FEATURE_MACROFOCUS: Indicates that macro focus mode is available.; Macro mode allows you to take a picture when the object is extremely close to the camera, such as 10 centimeters away.

CAMERA_FEATURE_FOCUSASSIST: Indicates that focus-assist mode is available.; Focus assist turns on the light before taking a picture in low-light conditions. Turning on the light improves focus performance in low-light conditions.

CAMERA_FEATURE_VFHWOVERLAY: Indicates that the viewfinder can use hardware acceleration for blitting.; Blitting is an operation where you copy the viewfinder buffer to the video display. For more information, see the SCREEN_USAGE_OVERLAY ( screen_set_window_property_iv() function) in the Screen and Windowing API.

CAMERA_FEATURE_REGIONEXPOSURE: Indicates that region exposure is available.; Region exposure allows you to perform spot and partial metering to regions of an image.

CAMERA_FEATURE_REGIONWHITEBALANCE: Indicates that region white balance is available.; Region white balance corrects image data in the user-specified region when correcting the white balance levels.

CAMERA_FEATURE_CONTINUOUSBURST

Indicates that continuous-burst mode is available.

Continuous burst allows for multiple images to be taken over an indefinite time-frame.

When CAMERA_FEATURE_BURST is available, but CAMERA_FEATURE_CONTINUOUSBURST isn't, then only the camera_take_burst() function can be used. The camera_start_burst() function will not work.

CAMERA_FEATURE_VFFACEDETECT: Indicates that face-detection is available in the viewfinder image stream.; Face detection permits you retrieve the coordinates of the faces detected in the scene via the accompanying preview metadata.

CAMERA_FEATURE_FACEDETECT: Indicates that face-detection is available in the still image stream.; Face detection permits you retrieve the coordinates of the faces detected in the scene via the accompanying still-image metadata.

CAMERA_FEATURE_PHOTOVFVARIABLEFRAMERATE: Indicates that variable frame rate is supported for photo viewfinder.; For more information, see the description for the CAMERA_IMGPROP_VARIABLEFRAMERATE.

CAMERA_FEATURE_AUTOEXPOSURE: Indicates that auto exposure is available.

CAMERA_FEATURE_AUTOWHITEBALANCE: Indicates that auto white balance is available.

CAMERA_FEATURE_MANUALEXPOSURE: Indicates that manual exposure is available.

CAMERA_FEATURE_MANUALWHITEBALANCE: Indicates that manual white balance is available.

CAMERA_FEATURE_NUMFEATURES: An end-of-list identifier.; Also indicates the total number of features recognized by the Camera library.
