20090268961 | COLOR-SATURATION CONTROL METHOD - For performing saturation control of one or more selected colors of the image, respective color values of the selected color(s) are pre-defined. Meanwhile, a specified pixel is selected from the image. Then distance(s) between the color space coordinate of the specified pixel and the color space coordinate(s) of the selected color(s) is (are) calculated. The color values of the specified pixel are thus adjusted depending on comparing results of the distance(s) with corresponding threshold distance(s). | 10-29-2009 |

20110234540 | BACKGROUND IMAGE UPDATING METHOD AND TOUCH SCREEN - A background image updating method is adapted to a touch screen including a first and a second image modules. A first and a second images are captured by the first and the second image modules as a first and a second background images, respectively. (a) Whether an absolute value of a brightness difference between a third image captured by the first image module and the first background image is greater than a predetermine value is compared. (b) If the result of the step(a) is yes, whether an absolute value of a brightness difference between a fourth image captured by the second image module and the second background image is greater than another predetermine value is compared. (c) If the result of the step(b) is yes, a fifth and a sixth images are captured by the first and the second image modules as the first and the second background images, respectively. | 09-29-2011 |

20120296905 | DENSITY-BASED DATA CLUSTERING METHOD - A density-based data clustering method executed by a computer system is disclosed. The method includes a setup step, a clustering step, an expansion step and a termination step. The setup step sets a radius and a threshold value. The clustering step defines a single cluster on a plurality of data points of a data set, and provides and adds a plurality of first boundary marks to a seed list as seeds. The expansion step expands the cluster from each seed of the seed list, and provides and adds at least one second boundary mark to the seed list as seeds. The termination step determines whether each of the data points is clustered, wherein the clustering step is re-performed if the determination is negative. | 11-22-2012 |
