    • Areas, allowed to overlap, are set for respective pixels in an image, and a maximum density value and a minimum density value, among inherent density values of the pixels in each area, are extracted and specified as maximum and minimum density values common to the pixels in the area. Among the density values specified from the overlapping areas, the largest minimum density value is set as a local minimum value and the smallest maximum density value is set as a local maximum value to thereby generate a minimum density plane and a maximum density plane including the pixels having the values. The density values of the pixels at the corresponding positions in the minimum density plane and the maximum density plane are corresponded to the common minimum and maximum values set separately, to thereby linearly convert the whole. Thereby, the pixel density values of the original image are linearly converted simultaneously.
    • 针对图像中的各个像素设置允许重叠的区域,并且提取每个区域中的像素的固有密度值中的最大浓度值和最小浓度值,并将其指定为 像素在该区域。 在从重叠区域指定的浓度值中,将最大最小浓度值设置为局部最小值,并将最小最大浓度值设置为局部最大值,从而生成最小密度平面和包括像素的最大密度平面 有价值。 在最小密度平面和最大密度平面中的相应位置处的像素的浓度值对应于单独设定的公共最小值和最大值,从而将整体线性地转换。 由此,原始图像的像素密度值被同时线性变换。

    • The differential apparatus comprises (a) a casing rotated by a driving force from outside; (b) a pair of opposing disc plates coaxially disposed in the casing, an opposing surface of each disc plate being formed with a circumferentially continuous groove winding such that a radial position changes at a constant period; (c) a plurality of balls rolling in opposing winding continuous grooves of both disc plates; and (d) a ball holder rotating integrally with the casing and having a plurality of radially extending guide holes, each guide hole movably receiving each ball, wherein the winding continuous groove of each disc plate circumferentially continuously has first guide regions each extending from a radially outer position to a radially inner position of each disc plate and second guide regions each extending from a radially inner position to a radially outer position, inflected regions each connecting each first guide region and each second guide region being larger in width and/or depth than the first guide regions and the second guide regions, whereby a contact stress between the balls and the winding continuous groove is decreased in the inflected regions.
