Examples with FaceDetectionListener android.hardware.Camera.FaceDetectionListener used on opensource projects

Example 1 with FaceDetectionListener

use of android.hardware.Camera.FaceDetectionListener in project android_packages_apps_Camera by CyanogenMod.

the class PhotoModule method startFaceDetection.

@TargetApi(ApiHelper.VERSION_CODES.ICE_CREAM_SANDWICH)
@Override
public void startFaceDetection() {
    if (!ApiHelper.HAS_FACE_DETECTION)
        return;
    // Workaround for a buggy camera library
    if (Util.noFaceDetectOnFrontCamera() && (CameraHolder.instance().getCameraInfo()[mCameraId].facing == CameraInfo.CAMERA_FACING_FRONT)) {
        return;
    }
    if (mFaceDetectionStarted || mCameraState != IDLE)
        return;
    if (mParameters.getMaxNumDetectedFaces() > 0) {
        mFaceDetectionStarted = true;
        mFaceView.clear();
        mFaceView.setVisibility(View.VISIBLE);
        mFaceView.setDisplayOrientation(mDisplayOrientation);
        CameraInfo info = CameraHolder.instance().getCameraInfo()[mCameraId];
        mFaceView.setMirror(info.facing == CameraInfo.CAMERA_FACING_FRONT);
        mFaceView.resume();
        mFocusManager.setFaceView(mFaceView);
        mCameraDevice.setFaceDetectionListener(new FaceDetectionListener() {

            @Override
            public void onFaceDetection(Face[] faces, android.hardware.Camera camera) {
                mFaceView.setFaces(faces);
            }
        });
        mCameraDevice.startFaceDetection();
    }
