如何使用AS3提高相机的质量？

Question

我正在尝试基于网络摄像头的应用程序.我开始这样的代码:

import flash.media.Camera;
import flash.media.Video;
var cam:Camera = Camera.getCamera();
a.vid1.attachCamera(cam);
a.vid1.smoothing = true;

我的问题是视频的质量.我正在使用iMac机器,其中相机质量很好.有没有办法提高相机输出的质量？

谢谢您的帮助.

这是一个示例代码

package
{
    import flash.display.DisplayObject;
    import flash.display.Sprite;
    import flash.display.StageAlign;
    import flash.display.StageScaleMode;
    import flash.events.ActivityEvent;
    import flash.events.MouseEvent;
    import flash.media.Camera;
    import flash.media.Video;

    public class iosTest extends Sprite
    {

        private var cam:Camera;
        private var vid:Video;


        public function iosTest()
        {
            super();

            // support autoOrients
            stage.align = StageAlign.TOP_LEFT;
            stage.scaleMode = StageScaleMode.NO_SCALE;
            cam = Camera.getCamera();

            if (!cam) 
            {
                trace("No camera is installed.");
            }
            else 
            {
                connectCamera();
            }
        }

        private function connectCamera():void 
        {
            cam.setMode(640, 480, 25); 
            cam.setQuality(0,100);
            vid             = new Video();
            vid.width       = cam.width;
            vid.height      = cam.height; 
            vid.attachCamera(cam);
            addChild(vid);    

            stage.addEventListener(MouseEvent.CLICK, clickHandler);
        }

        private function clickHandler(e:MouseEvent):void 
        {

            return;

            switch (cam.width) {
                case 160:
                    cam.setMode(320, 240, 10); 
                    break;
                case 320:
                    cam.setMode(640, 480, 5); 
                    break;
                default:
                    cam.setMode(160, 120, 15); 
                    break;
            } 
            removeChild(vid);           
            connectCamera();
        }

    }
}
