摘要：PROBLEM TO BE SOLVED: To provide a system which makes users putting on no glasses observe a picture without degradation of the picture quality and gives additional information to users putting on glasses while observing the same picture, by giving a difference between pictures to be observed with a shutter and pictures to be observed without the shutter. SOLUTION: One frame picture is divided into sub-fields to be successively displayed along the time base, and they are divided to sub-fields for displaying additional information and sub-fields for displaying a picture obtained by subtracting the additional information from the original frame picture. The shutter is opened and closed synchronously with the vertical frequency of sub- fields. Thus users using the shutter can see the additional information for the purpose of seeing only the picture having the additional information subtracted. Meanwhile, users who don't use the shutter see the original frame picture. COPYRIGHT: (C)2003,JPO
