Abstract
PURPOSE:To ensure the highly efficient use of a buffer memory in accordance with the slip size and to increase the reading speed, by adding the hardware such as a control circuit, the address counters of X and Y directions, etc. CONSTITUTION:The video information given from a line sensor 11 is supplied to a video buffer memory 12 having plural memory chips. Boh X and Y direction address counters 13 and 16 are provided to the memory 12. The chip addresses of the memory 12 are applied to the counters 13 and 16 in accordance with the slip size, and at the same time the array conversion control information is applied to a status register 15 from a control part 19. The addresses on the memory 12 are decided by converting circuits 14 and 17 with the chip addresses given from the counters 13 and 16 plus the area status signal given from the register 15. Then the chip address signal is decoded by a decoder 18 to deliver the signal to select the chip within a memory 18. Thus the memory 18 is used in a highly efficient way in accordance with the slip size.
