Abstract:
1. An electronic apparatus comprising a picture generation apparatus and a picture display apparatus, said picture generation apparatus comprising: a synchronization signal generator that generates a picture synchronization signal; a picture generator that generates picture data in a horizontal resolution of m′ and a vertical resolution of n′ in synch with the picture synchronization signal; a picture generation controller that specifies an m′×n′ region in a memory, having a horizontal resolution of M (M>m′) and a vertical resolution of N (N>n′), and stores the picture data in said region in synch with the picture synchronization signal; and a picture signal generator that reads data from the memory and generates a picture signal in the vertical resolution of N and horizontal resolution of M in synch with the picture synchronization signal, and said picture display apparatus comprising: a picture display controller that specifies a displaying region on a picture display surface, having a horizontal resolution of m (M>m) and a vertical resolution of n (N>n); and a picture display that cuts from the picture signal a picture corresponding to the displaying region specified by the picture display controller and displays the picture on the picture display surface, wherein said electronic apparatus is further provided with a controller that controls the picture generation controller in the picture generation apparatus and the picture display controller in the picture display apparatus, and that independently controls a position of the region in the memory for storing the picture data and a position of the displaying region on the picture display surface of the picture display apparatus.
