web前端如何调用本地摄像头进行拍照?


如果纯js可以做到就更好了,js+flash实现也可以,不知道html5可否做到?
求一个功能演示的例子

flash html5 JavaScript

JS调用好像不行,一般都是用Flash的Com,这是写好的一个Flash调用摄像头的,参考一下吧

   
  package {
  
import flash.display.Sprite;
import flash.text.*;
import flash.media.Camera;
import flash.events.StatusEvent;
import flash.events.ActivityEvent;
import flash.media.Video;

public class CameraEx extends Sprite
{
private var label:TextField;
private var camera:Camera;

public function CameraEx()
{
label=addLabel("CameraEx");

camera=Camera.getCamera();

if(camera!=null){
camera.addEventListener(StatusEvent.STATUS,statusHandler);
camera.addEventListener(ActivityEvent.ACTIVITY,activityHandler);

var video:Video=new Video(200,200);
video.attachCamera(camera);
addChild(video);
video.x=20;
video.y=20;
}
else{
label.text="不能使用";
}
}

private function statusHandler(evt:StatusEvent):void{
if(camera.muted) label.text="不能使用";
}

private function activityHandler(evt:ActivityEvent):void{
if(evt.activating){
label.text="检测开始";
}
else{
label.text="检测停止";
}
}

private function addLabel(text:String):TextField{
var label:TextField=new TextField();
label.autoSize=TextFieldAutoSize.LEFT;
label.text=text;
addChild(label);
return label;
}
}
}
