ABSTRACT:
To provide an apparatus for painting figures which is improved in painting capability better than the conventional art even when a path to an external memory section is narrow. In order to simultaneously write previously generated painting information and read data required for generating painting information later in the painting coordinate generating section and the painting information generating section on the painting apparatus, while painting information is generated, first and second buffers are provided as a buffer section for storing painting information generated in the painting information generating section, and address information storing sections corresponding to the first and second buffers are provided as an address generating section for generating an address for storing painting information, which is accumulated in the buffer section, in an external memory section. When reading and writing is carried out on the first buffer, the following operations are performed in parallel: outputting data, which is previously written to the second buffer, to the external memory section, reading data required for the next processing from the external memory section.
