Nevertheless, since a player's game posture changes every player or by a game status, it can be considered that a player approaches a gaming machine to about one half of the assumed distance d.

Furthermore, as shown in Fig. 9, pixel lines are not conspicuous so long as the number of stripes is equal to or larger than the peak value (about 5 - 8) for blue or red pixel lines even if it is 35 or less. In this modified example, therefore, by using the correction value ⁇ , the number of stripes is made within a hatched range in Fig. 9.
