相机聚焦，相机截屏

相机聚焦：

using UnityEngine;using System.Collections;namespace Vuforia{    public class focus : MonoBehaviour    {        // Use this for initialization          void Start()        {        }        void Update()        {            CameraDevice.Instance.SetFocusMode(CameraDevice.FocusMode.FOCUS_MODE_CONTINUOUSAUTO);        }    }}
