PURPOSE:To attain a high processing speed without need of transfer of all data in the case of revision of data different from a conventional display device and to attain a further higher processing speed with parallel processing made it possible by allowing 1st and 2nd processors to store CG data respectively and transferring and displaying only revised data. CONSTITUTION:When information relating to display is fed to a 1st processing section 1 externally, a CG data management section 5 of the 1st processing section 1 calculates the effect on CG data stored in a CG data storage section 4 to obtain CG data to be revised, that is, revision data. The CG data management section 5 of the 1st processing section 1 stores the revision data to a revision data buffer 3. The revision data stored in the revision data buffer 3 are read by a CG data picture processing section 7 in the 2nd processing section 2. The CG data picture processing section 7 updates the CG data stored in a revision CG data storage section 6 to generate picture data from the CG data. |
