easing rotation as3

How can I ease the rotation of an object between returned values?

var mycam:Camera = Camera.getCamera ();
trace (mycam);



video1.attachCamera(mycam);


function update(event:Event):void
{
	var activity:Number = mycam.activityLevel;
	if (activity>0)
	{
		
		
		red.rotation=red.rotation+ (activity * .45);
		
		trace(activity);
	}
}
function camstart (event:Event)
{
	
}
mycam.addEventListener (ActivityEvent.ACTIVITY,camstart);
addEventListener (Event.ENTER_FRAME,update);
