DEVICE OF CONTINUOUSLY CHANGING DIMENSION OF SAMPLE ON RASTER TYPE FIELD SCREEN |
摘要 |
Apparatus for continuous variation of object size on a raster type video screen in a television game. The input of a voltage controlled oscillator is varied by a game controller. The output of the oscillator drives horizontal and vertical counters at rates corresponding to the object size. These counters provide respectively horizontal and vertical addresses to a picture generator read only memory. The faster the counters are incremented the smaller the object; and with regard to the vertical address, horizontal lines of the picture are actually skipped in order to reduce the size of the object. |
