<p><P>PROBLEM TO BE SOLVED: To provide technique for obtaining a smooth luminance change while reducing a data amount to be stored in a game machine. <P>SOLUTION: A first design gradation value to be derived from a design value S1(0), for example, is set in a gradation control IC for controlling luminance, based on the gradation value concerning a schedular 222. As a light emission period B1(0) elapses from the setting of the first design gradation value, a second design gradation value to be derived from a design value S1(0) is set in a gradation control IC. During the light emission period B1(0), an interpolation gradation value is derived based on the first design gradation value, the second design gradation value, the light emission period B1(0), and an elapsed interval from the setting of the first design gradation value. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
