The continuous development and expansion of media greatly rewrite cultural reality of the whole human society. In digital media period, the media culture with its huge inclusiveness and absorption capacity affects everything around and makes the cultural expansion ability and the transformation ability strengthened constantly. Images overwhelm text and other symbols to become visual overlord and make “the world descripted as the image”, when glance over and fast browsing become normal, the situation turning a blind eye on “the visualized things” that can not produce visual stimulation becomes more and more frequent. Involving in virtual space world constructed by network, the controlled media makes the public access to the state of “existence forgotten” and lose sentimental communication “on the scene”, therefore, the confirmation of selfidentity is also in strongly unreal color.
