In general, there is a service that needs to correspond "anytime" "anywhere". However, fault-tolerant systems with fully redundant hardware used for business are very expensive and cost effective. In addition, problems such as occurrence of down time of the entire system due to maintenance and switching to a backup circuit occur, and it is a problem that it is difficult to secure a bypass route. In this paper, the method to construct a fault tolerant system at low cost only by software processing is proposed. Especially focused on video processing and transmission. Even if arbitrary images are simultaneously displayed by a plurality of processes as the characteristics of the image, the influence on the entire display is not very large. Therefore, images simultaneously processed by a plurality of pipelines are collectively displayed. As a result, the pipeline in which a series of moving image processing is processed without stopping, is constructed. As a basic system, the system that duplicated simple image processing, and confirmed that there is no problem even if one side stops, is constructed.
In this research, in order for autostereoscopic display of dual projection types to display the image with larger parallax, we improved a new optimization method of the two projector images. We achieved that aim by deriving a new update formula in addition system and adjusting the target light field and weight matrix to create the area that saturates light.
