Filed: 2009-04-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image processing apparatus and method that can generate a gradation correction parameter while taking local dark part pixels into consideration, and then can improve gradation reproducibility.  <P>SOLUTION: The image processing apparatus includes a generation means for generating a luminance histogram from luminance values for each pixel of an input image, a determination means for determining whether each of the pixels of the image is a local dark part pixel which is locally dark from the luminance value of the pixel and luminance values of peripheral pixels thereof for each pixel of the image, and a generation means for generating the gradation correction parameter for correcting gradations of the image using the luminance histogram and the total number of local dark part pixels. When the total number of the local dark part pixels is larger than a predetermined threshold, the generation means detects a gradation of interest of the highest frequency within a range obtained excluding a luminance area including gradations of the local dark part pixels from the luminance histogram, and generates a gradation correction parameter for increasing gradations near the gradation of interest including the gradation of interest.  <P>COPYRIGHT: (C)2011,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To enable a player to estimate whether it is a small winning game or a latent probability variable jackpot game in a special mode.  <P>SOLUTION: In a variation table 303 in the special mode, the number of times of variations in the special mode is changed for each symbol changed to a latent mode. The same special mode is prepared for the small winning game and a 2R latent probability variation jackpot game, and the number of times of the variations for each symbol is set so as to be different in the small winning game and the 2R latent probability variable jackpot game. A first pattern group 501 and a second pattern group 502 are provided, and the number of times of the variations in the special mode is larger in the 2R latent probability variable jackpot game than in the small winning game. Thus, it is estimated that the possibility of a low probability state is higher as the special mode continues longer. By setting 50 times only for the 2R latent probability variable jackpot game (pattern "J") and not setting it to the small winning game, the high probability state is established when the variation continues 31 times or more.  <P>COPYRIGHT: (C)2011,JPO&INPIT
