    Abstract: A mouse with coordinate and suspension positioning functions, which receives a directional light produced by an external illuminator. A second image sensor receives and converts the directional light into an electrical signal, and accordingly produces a directional image corresponding to the directional light. A second memory stores the directional image. When an image captured by a first image sensor cannot be focused, a processor enables the second image sensor and the second memory in order to analyze the directional image and obtain a rotating angle of the directional light for further fulfilling a coordinate positioning.

    Abstract: A rapid color recognition method is provided. In the method, an area for representing a color of the pixel is identified according to the basic color component data of the pixel, and then the color code is outputted according to a predetermined color classification table of the area. In the method, since an isosceles right triangle plane is provided by extending and scaling the regular triangle plane by using one side of the regular triangle plane as a base, wherein the regular triangle plane is provided by normalizing the basic color component data. Therefore, the basic color component data is normalized without division operation, and thus the complexity of the operation of the color recognition is reduced.

    Abstract: A linear image filter and the corresponding filtering method is disclosed. In conventional linear image filters, only one pixel can be processed during a single cycle because it is applied to an odd-order filter matrix. Consequently, the present linear image filter and the corresponding method expand the original odd-order filter matrix into an even-order matrix by adding a row and a column of zeros at the topmost/bottommost and the rightmost/leftmost of the original filter matrix. This not only increases the filtering speed of the linear image filter because four pixels can be simultaneously reconstructed, but also fully utilizes current 32-bit processors because a pixel is currently represented only as an 8-bit value.

    Abstract translation: 公开了一种线性图像滤波器和相应的滤波方法。 在传统的线性图像滤波器中,由于将其应用于奇数阶滤波器矩阵,因此在单个周期中只能处理一个像素。 因此,本线性图像滤波器和相应的方法通过在原始滤波器矩阵的最上/最底和最右/最左边添加一行和一列零将原始奇数阶滤波器矩阵扩展为偶数矩阵。 这不仅增加了线性图像滤波器的滤波速度,因为可以同时重构四个像素,而且还充分利用当前的32位处理器,因为像素当前仅被表示为8位值。
