如何使用 AS3 提高相机的质量? [英] How to increase the Quality of the camera using AS3?

问题描述

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:

I'm trying for a webcam based application. I started the code like this:

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.我使用的是 iMac 机器，相机质量很好.有什么方法可以提高相机输出的质量吗?

My problem is that the quality of the video. Im using an iMac machine, in which camera quality is good. Is there any way to increase the quality of the camera output?

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();
        }

    }
}
