How to disable depth of field if Player moves Mouse X or Mouse Y for 2 seconds on trigger enter?

HelloI came up with a script that when the player enters the trigger it activates depth of field for a few seconds then disappears and it works like a charm now i was wondering how i can make it so the when the player enters the trigger they cannot disable the blur unless Input.GetAxis("Mouse X") or Input.GetAxis("Mouse Y") is being moved for at least 2 seconds. I started by adding a bool which is private bool isMovingMouseXY; but I do not know where to start after that.

i have included a mockup of what im trying to make Here

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityStandardAssets.ImageEffects;
 
 public class StartTriggerEffect : MonoBehaviour {
 
     public VignetteAndChromaticAberration vig;
 
     public DepthOfField34 bloomf;
 
     private bool isMovingMouseXY;
 
     // Use this for initialization
     void Start() {
         //Camera.main.GetComponent<VignetteAndChromaticAberration>().enabled = false;
         Camera.main.GetComponent<DepthOfField34>().enabled = false;
     }
 
     private void Update()
     {
 
     }
 
     // Update is called once per frame
     public IEnumerator OnTriggerEnter(Collider other)
     {
         if (other.tag == "Player")
         {
             //Camera.main.GetComponent<VignetteAndChromaticAberration>().enabled = true;
             Camera.main.GetComponent<DepthOfField34>().enabled = true;
             //yield return new WaitForSeconds(2); Camera.main.GetComponent<VignetteAndChromaticAberration>().enabled = false;
             yield return new WaitForSeconds(2); Camera.main.GetComponent<DepthOfField34>().enabled = false;
 
         }
     }
 }
