<input type="file" capture="camera" accept="image/*" id="cameraInput" name="cameraInput">
如果只想调用相册或者选择文件
<input type="file" name="file" accept="image/*" >
如果想调用摄像头
<input type="file" name="file" capture="camera">
html5中的video这个标签是引入视频的，通过navigator.getUserMedia去获取摄像头的视频流，所以要在事件里用关闭的代码都不能执行关闭摄像头，只有关闭网页，摄像头才关闭。html5打开摄像头代码：

可以的<input type="file" accept="video/*capture=camcorder">
<input type="file" accept="audio/*capture=microphone">
<input type="file" accept="image/*capture=camera">直接调用相机
<input type="file" accept="image/*" />调用相机 图片或者相册
还是要根据手机的类型来说，有些手机只能调相机，有些手机只能调相册，或者两者都行。
