PURPOSE:To efficiently accumulate and flexibly control a material image by storing address data, picture element data arranged in the order of addresses and mixed rate data in a storage device as one group at the time of storing the material image (parts image) to be composed. CONSTITUTION:Plural parts image files 21 are stored in the storage device 4, and at the time of displaying the stored parts image, address data, parts image data and mixed rate data in a parts image file 21 are respectively transferred to an address memory 12 in an address data generating circuit 7, a parts image memory 13 in a picture element data generating circuit 8 and a fixed rate memory 14 in a mixed rate data generating circuit 9. Consequently, background data are not required for the storage of parts images and data can be efficiently stored. |
