    • Noise reduction is performed on the basis of characteristics of an image in a detection range. A noise reduction block 4′ performs a second-order differentiation process and a symmetry process to decide adjacent pixels with which noise reduction is preformed for an attention pixel. With the pixel level of the attention pixel in the detection range and the pixel levels of adjacent pixels used for noise reduction, an arithmetic mean processing section 16 calculates a mean value. A median filter 17 selects a median value. With the number of pixels used for noise reduction, it is determined whether the image in the detection range contains a flat portion, a ramp portion, or an edge. The mean value and the median value are weight-added with a weighted coefficient that are changed on the basis of characteristics of the image. The result is substituted for the level of the attention pixel. When the attention pixel is an isolated point, an all-pixel median filter section 31 selects a medium value of the levels of all the pixels in the detection range including the attention pixel and substitutes the median value for the level of the attention pixel.
    • 基于检测范围内的图像的特性进行降噪。 降噪块4'执行二阶微分处理和对称处理,以确定针对注意像素执行降噪的相邻像素。 利用检测范围内的关注像素的像素级和用于降噪的相邻像素的像素级,算术平均处理部16计算平均值。 中值滤波器17选择中值。 利用用于降噪的像素数量,确定检测范围内的图像是否包含平坦部分,斜坡部分或边缘。 平均值和中值是加权系数,加权系数根据图像的特性而改变。 结果代替注意像素的级别。 当注意像素是孤立点时,全像素中值滤波器部分31选择包括关注像素在内的检测范围内的所有像素的电平的中值,并代入关注像素的电平的中值。

    • A first conveying mechanism includes an intermediate conveying roller for conveying a recording sheet, an intermediate conveying roller shaft for supporting the intermediate conveying roller, an intermediate conveying roller drive mechanism for rotationally driving the intermediate conveying roller shaft, and a roller control mechanism for controlling movements of the intermediate conveying roller relative to the intermediate conveying roller shaft. The roller control mechanism performs skew correction along with conveying the recording sheet by rotating the intermediate conveying roller integrally with the intermediate conveying roller shaft while the intermediate conveying roller drive mechanism rotationally drives the intermediate conveying roller shaft and stops the rotational drive of the intermediate conveying roller shaft performed by the intermediate conveying roller drive mechanism after the skew correction to cause the intermediate conveying roller to be movable within a predetermined range in the axial direction of the intermediate conveying roller shaft.

    • Memory cells containing two split sub-lithographic charge storage nodes on a semiconductor substrate and methods for making the memory cells are provided. The methods can involve forming two split sub-lithographic charge storage nodes by using spacer formation techniques. By removing an exposed portion of a fist poly layer between sloping side surfaces or outer surfaces of spacers while leaving portions of the first poly layer protected by the spacers, the method can provide two split sub-lithographic first poly gates. Further, by removing an exposed portion of a charge storage layer between sloping side surfaces or outer surfaces of spacers, the method can provide two split, narrow portions of the charge storage layer, which subsequently form two split sub-lithographic charge storage nodes.
    • 提供了包含半导体衬底上的两个分裂子光刻电荷存储节点的存储单元以及用于制造存储单元的方法。 这些方法可以包括通过使用间隔物形成技术形成两个分裂的亚光刻电荷存储节点。 通过在间隔物的倾斜侧表面或外表面之间除去第一多晶硅层的暴露部分,同时留下被间隔物保护的第一多晶硅层的部分,该方法可以提供两个分裂的次光刻的第一多晶硅栅极。 此外,通过去除间隔物的倾斜侧表面或外表面之间的电荷存储层的暴露部分,该方法可以提供电荷存储层的两个分开的窄部分,其随后形成两个分裂的亚光刻电荷存储节点。
