PROBLEM TO BE SOLVED: To solve the problem that, though a processing performed by a drawing part includes a processing for treating overlapping between objects, processing time prediction has been performed without taking the processing into consideration hitherto, and thereby accuracy has been low.SOLUTION: An image is divided into blocks having a prescribed size, and a coefficient showing dispersion of location of objects is calculated, and the coefficient, the number of commands of a processing between the objects and a processing time of the commands are multiplied together, to thereby determine a time for processing overlapping between the objects. A prediction time required for execution of the commands for drawing the objects is added thereto, and the result is used as a prediction value of the processing time required for drawing the image.SELECTED DRAWING: Figure 6 |
