试试这个

<!DOCTYPE html> 
<html lang="en"> 
<head> 
<meta charset="utf-8"> 
<script src="http://code.jquery.com/jquery-1.7.2.min.js"></script> 
<script src="http://www.xarg.org/download/jquery.webcam.min.js" type="text/javascript">  </script> 
</head> 
<body> 

<div id="webcam"> 
<span><a href="javascript:webcam.capture();void(0);">Take a picture instantly</a>  </span> 
</div> 

<script type="text/javascript"> 
jQuery("#webcam").webcam({ 
width: 320, 
height: 240, 
mode: "save", 
swffile: "/swf/jscam.swf", 

onCapture: function() { 
webcam.save('/upload.php'); 
    $('#webcam').hide(); 
    $('#image').show(); 
    setInterval(function() { 
var d = new Date(); 
jQuery("#image").attr("src", "/upload/image.jpg?"+d.getTime()); 
}, 2000); 
} 
}); 

</script> 

<img style="display:none;" id="image" src="/upload/image.jpg?<? echo rand(0,1000); ?>" width="320" border="0" alt="" /> 

</body> 
</html>

和PHP

$str = file_get_contents("php://input"); 
file_put_contents("/upload/image.jpg", pack("H*", $str));

不要忘记设置上载权许可文件夹和正确的文件路径。
