PROBLEM TO BE SOLVED: To display each translucent drawing object of high quality by a processing of low load, in superposing and composing two or more drawing objects. SOLUTION: A drawing pattern acquisition part 32 acquires a drawing pattern 23 generated on the basis of a result of comparison of a numerical value successively generated from a given numeric row and an alpha value indicating a degree of transparency in composing the drawing objects, successively performed by every image element. A drawing processing part 33 performs the drawing by determining which image element of a new drawing object or an image drawn before is to be drawn on the basis of the acquired drawing pattern 23. Here, the drawing processing part 33 determines the drawing on the basis of the drawing patterns 23 respectively generated from different numeric rows of a small absolute value of a coefficient of correlation to the superposed drawing objects.
