    • A capacitive touch device and a sensing method thereof are disclosed. The capacitive touch device includes a touch panel and a plurality of touch detection units. The touch panel includes first sensing lines and second sensing lines. The position of a touch between a last one of the first sensing lines and a first one of the second sensing lines is calculated according to sensed values respectively corresponding to a first sensing line prior to the last one of the first sensing lines, the last one of the first sensing lines and the first one of the second sensing lines. The present invention is capable of avoiding the problem that the frame rate is reduced significantly because of the data transmission between the first and second touch detection units.

    • A fast line drawing method. First, the coordinates of two end points are received and a current point is assigned to one of the end points. The differences of x and y coordinates (nullx and nully) and the sum of error E are computed, the integer part of nullx over nully is denoted as Q. The current point is checked to determine whether it has reached the end point. If not and the value of E is negative, a point at the current point is drawn. The y-coordinate of the current point and E are updated by (Ynull1) and (Enull2nullx) respectively if E is non-negative, a span of pixels from (X,Y) to (XnullQ-1,Y) are drawn if the coordinate of last of Q points is less than the end point. Otherwise, a span of pixels from (X,Y) to (x2,Y) are drawn.
    • 快速线条画法。 首先,接收两个端点的坐标,并将一个当前点分配给一个端点。 计算x和y坐标(DELTAx和DELTAy)的差异和误差E的总和,DELTAx的DELTAx的整数部分表示为Q.检查当前点以确定其是否已到达终点。 如果不是,并且E的值为负,则绘制当前点的点。 如果E是非负的,分别从(X,Y)到(X + Q-1)的像素的跨度,分别更新当前点和E的y坐标(Y + 1)和(E-2DELTAx) 如果Q点的最后坐标小于终点,则绘制Y)。 否则,绘制从(X,Y)到(x2,Y)的像素跨度。

    • A method for converting N-bit image data of a digital image into M-bit image data, in which NnullMnullK, K>0, is disclosed. The method is adapted to be used for dithering in an image processing system or a computer graphic system. For example, an N-bit red color value of each pixel of the digital image can be converted into an M-bit red color value by this method with little or no color deviation. According to the method, a difference of the most significant n bits and the least significant n bits of the N-bit image data of a pixel is used as a preliminary criterion for color value conversion, in which n is preferably equal to K. An apparatus for converting N-bit image data of a digital image into M-bit image data, in which NnullMnullK, K>0, is also disclosed. The apparatus includes a subtraction operator for realizing the difference of the most significant n bits and the least significant n bits of the N-bit image data of the pixel.
    • 公开了一种将数字图像的N位图像数据转换成M位图像数据的方法,其中N-M = K,K> 0。 该方法适用于图像处理系统或计算机图形系统中的抖动。 例如,数字图像的每个像素的N位红色值可以通过该方法被很少或没有颜色偏差转换成M位红色值。 根据该方法,使用像素的N位图像数据的最高有效n位和最低有效n位的差作为颜色值转换的初步准则,其中n优选地等于K. 还公开了将数字图像的N位图像数据转换为M = K,K> 0的M位图像数据的装置。 该装置包括用于实现像素的N位图像数据的最高有效n位和最低有效n位的差的减法运算器。
