    • An image processing method for reducing noise of an image to be filtered; the method includes a step of creating shrunken image of shrinking ratio r×r (where r is a natural number) by averaging the pixel values for each pixel in a block for every r pixels, a step of obtaining the pixel value in the shrunken image that correspond to the focus pixel in the source image by performing linear interpolation from the shrunken image pixels, a step of determining the noise reduction filter from the focus pixel and reference pixel in the shrunken image, and a step of computing the compensated pixel value of the focus pixel in the source image by weighted sum of each pixel value applying the filter to the focus pixel in the source image and the corresponding shrunken pixel.
    • 一种用于降低要滤波的图像的噪声的图像处理方法; 该方法包括通过对每个r个像素的块中的每个像素的像素值进行平均来创建缩小率r×r(其中r是自然数)的缩小图像的步骤,获得缩小图像中的像素值的步骤 通过从缩小图像像素执行线性插值,对应于源图像中的焦点像素的步骤,从缩小图像中的聚焦像素和参考像素确定降噪滤波器的步骤,以及计算补偿像素值的步骤 源图像中的焦点像素通过将滤光器应用于源图像中的焦点像素和相应的缩小像素的每个像素值的加权和。

    • A battery pack has a current detector, a voltage detector, a temperature sensor, and a CPU. The current detector detects a current flowing in secondary cells. When the current flows in the secondary cells, the voltage detector detects the voltage of the secondary cells, and the temperature sensor detects the temperature of the secondary cells. The CPU calculates the extent of deterioration of the secondary cells. The CPU calculates the remaining capacity of the secondary cells, based on the open voltage of the secondary cells, OCV, obtained by the equation: OCV=DV+K.times.DI.times.T.times.F where DV represents the voltage of said secondary cells when used; DI, a current flowing in said secondary cells; T, the temperature of said secondary cells; F, the extent of deterioration of said secondary cells; and K, a predetermined proportional constant.
    • 电池组具有电流检测器,电压检测器,温度传感器和CPU。 电流检测器检测在二次电池中流动的电流。 当电流在二次电池中流动时,电压检测器检测二次电池的电压,温度传感器检测二次电池的温度。 CPU计算二次电池的劣化程度。 CPU基于通过以下等式获得的二次电池的开路电压OCV计算二次电池的剩余容量:OCV = DV + KxDIxTxF其中DV表示当使用时所述二次电池的电压; DI,在所述二次电池中流动的电流; T,所述二次电池的温度; F,所述二次电池的劣化程度; 和K,一个预定的比例常数。
