Abstract

PURPOSE:To improve the efficiency of utilization of a memory device when picture data are inputted with its memory area equally divided into more than one page, by counting unused pages of the area and by comparing the number of those pages with that of pages required for one original. CONSTITUTION:Picture data VD is inputted to and outputted from memory 3a via input and output ports 11-14, which are controlled by port control circuits 15-18 and the order of all pages and the start and stop of circuits 15-18 are controlled by CPU22. Further, CPU22 is put into operation under the command of system controller 10. In memory control part 3b, a memory information table is arranged and in this table, one-bit flags correspond to respective pages of the memory area equally divided into N pages. When an input request is sent to memory 3, the number of unused pages in this table is counted and compared with the number (n) of required pages; when the number is enough, the memory area is secured and when not, it is judged that input operation is impossible. After the input operation, flags of unused pages among pages secured as the input area are reset.
