Object Texture Showing Blur In Game

Hi

I am creating 2d game with unity. My player are moving on y direction & some obstacle are coming from opposite direction.The problem is when user are moving some blur effect are showing on obstacle.Please suggest me how can i remove it.

I have also fallow this link but non of them are giving solution for it.

I am Writing Player Movement script :-

 private MainScript mainScript;
	 public float speedupward = 0.10f;
	
	// Script Created by Sonu Odesi...
	
	// Use this for initialization
	void Start () {
	mainScript = GameObject.Find("GameManager").GetComponent<MainScript>();
	}
	
	// Update is called once per frame
	void Update () {
	if(mainScript.gameState==GameState.GameRunning){			
			   
		   transform.Translate(Vector3.up* speedupward * Time.smoothDeltaTime);	      
		  
		}	
	}

Camera Movement Script:-

private bool followPlayer;
private bool followRocket;

private GameObject _player;
private GameObject rocket;
private Transform myTransform;
private float cameraPosition;
private GameObject _MyPlayer;

// Use this for initialization
void Start () {		
	
	_player=GameObject.FindGameObjectWithTag("KidPlayer");
	_MyPlayer = _player.transform.root.gameObject;
	myTransform = this.transform;
	Application.targetFrameRate=60;

}

// Update is called once per frame
void LateUpdate () {
	
		if(_player.rigidbody.isKinematic && followPlayer){	
			ScoreManagerScript.startScore = true;

		    myTransform.parent = _MyPlayer.transform;
		}
	
		if(followRocket){
			myTransform.position = new Vector3(myTransform.position.x,_player.transform.root.transform.FindChild("PowerBoosterParent").transform.position.y+7,myTransform.position.z);
		
		}
}

public bool FollowPlayer{
	set{followPlayer = value;}
	get{return followPlayer;}
}	

public void FollowRocket(GameObject go,bool follow){
	rocket = go;
	followRocket = follow;
}

The blurring in your picture is a photograph ā€“ subject to long exposures that will blend multiple actual frames together (similar to the human eye). This is nice for showing the perceived effect, but Iā€™m not sure that Unity is actually causing this blurring. Does this blurring show up when you take a screen shot on the actual device itself? If not, then I suspect that the problem is due to ghosting of the LCD ā€“ slow image response and whatnot.
