<P>PROBLEM TO BE SOLVED: To provide a game picture with a clear impression without practically having effect on the impression of the entire game picture. <P>SOLUTION: An unsharp picture is firstly generated based on the original picture. Where, a method for generating the unsharp picture may employ various well-known systems. Next, a differential picture is generated by obtaining a difference between the brightness of the unsharp picture and the brightness of the original picture, provided that the brightness of the differential picture is zero in a pixel having a negative brightness value when the brightness of the original picture is reduced from the brightness of the unsharp picture. In addition, inverting the brightness of the differential picture generates the inverted differential picture. A displaying picture is obtained by multiplying the inverted differential picture by the original picture for every pixel. <P>COPYRIGHT: (C)2004,JPO |
