PROBLEM TO BE SOLVED: To provide a drawing processing device that can make a graphic logical arithmetic output at a high-speed with a simple configuration. SOLUTION: In the case that a graphic indicates an internal state in a step S38, color is recalculated. When an 'internal state' in a drawing state table is not idle, since an X coordinate value (let it beα) of a vector having already been set inside is to be at a 'drawing start position', the range fromαto an X coordinate -1 of the vector is painted by a head color in the 'internal state' (step S41). Then, in the case that vectors other than the above vector is registered, the color value of the vector and the color value of the other vectors are logically synthesized by using a prescribed arithmetic code to calculate color values (steps S43-S46). Then, the 'drawing start position' is set to the X coordinate of the vector (step S46) and IDs are registered to be arranged in the descending order of the ID in the 'internal state' of the drawing state table (step S47). The logical arithmetic synthesis processing in the internal state is completed by the processing above. |
