这个我刚好做过使用mui和html

 <div id="picture" class="mui-popover mui-popover-action mui-popover-bottom">
            <ul class="mui-table-view">
                <li class="mui-table-view-cell">
                    <a  id="toPhoto">拍 摄</a>
                </li>
                <li class="mui-table-view-cell">
                    <a  id="toChoose">从相册选择</a>
                </li>
            </ul>
            <ul class="mui-table-view">
                <li class="mui-table-view-cell">
                    <a href="#picture"><b>取消</b></a>
                </li>
            </ul>
     </div>

////拍照上传
 $("#toPhoto").click(function(){
       mui('#picture').popover('toggle');
       navigator.camera.getPicture(function successcallback(message) {
             //要实现的功能


                }, function failcallback(message) {

                }, {
                    quality : 30,
                    destinationType : Camera.DestinationType.DATA_URL,
                    sourceType : Camera.PictureSourceType.CAMERA
            });
     });

 //本地选图片上传
    $("#toChoose").click(function(){
        mui('#picture').popover('toggle');
        navigator.camera.getPicture(
           function successcallback(message) {

                  //实现的业务


           }, 
           function failcallback(message) {

           }, 
           {
           quality : 30,
           destinationType : Camera.DestinationType.DATA_URL,
           sourceType : Camera.PictureSourceType.PHOTOLIBRARY
       });
    });

如果不行可加我微信||QQ，给你完整代码：2549789059

在config接口中的jsApiList属性添加调用相册，和摄像头。然后再ready中就可以调用了！
