PURPOSE:To process drawing instruction sequences fast by analyzing the drawing instruction sequences in blocks, determining the execution of and synchronous control over the drawing instruction sequences, and executing the drawing instruction sequences in parallel processing blocks in parallel. CONSTITUTION:At a display request from a client program 101, the dispatcher 105 of a drawing server 104 after analyzing a drawing instruction transferred from the client program 101 finds one drawing processing thread (106a or 106b) in a free state between drawing processing threads 106a and 106b according to thread execution state information 107, and actuates it to execute the drawing instruction. The actuated drawing processing thread (106a or 106b) performs the drawing processing by operating display system hardware 108 according to the instruction, and sets information on the thread (106a or 106b) of the thread execution state information 107 to a free state after the drawing processing ends. |
