摘要： There is provided a liquid crystal display control device which can display pictures in a magnification mode by using only a memory having low-speed access and a low storage capacity. When a video signal has intermediate resolution or less, the enlargement processing is performed by a frame memory, a line memory and an enlargement processing control circuit. If the input operation and the output operation to and from the frame memory are synchronized with each other, it is sufficient for the frame memory to have a storage capacity of two lines. When the video signal has the same high resolution as a liquid crystal display panel, the video signal is output through a gate circuit to a display timing generating circuit, and it is displayed in a through mode. In this case, no processing is performed by the frame memory or the like.

摘要： In the electric power system protective control system, a plurality of protective control apparatuses each having a protective control function to an electric power system are distributed and connected through a communication network to each other so that data communication is permitted among the respective protective control apparatuses. Each of the protective control apparatuses is carried out a process of executing a control operation related to the protective control function of the own apparatus according to a program module. The program module migrates through the communication network to the own apparatus along a predetermined route of migration. Each of the protective control apparatuses executes a process of migrating the program module from the own apparatus to another protective control apparatus. The another protective control apparatus is determined to a next destination of migration according to the route of migration. In a case where the program module is not migrated by the migration process to the next destination protective control apparatus, each of the protective control apparatuses executes a process of changing a next destination of migration of the program module to a predetermined protective control apparatus except for the next destination protective control apparatus, making it possible to prevent the program module from stopping.
