Abstract: An input pixel value of input image data is converted to a pixel value within a predetermined range, and a pixel value of pixel of interest of the converted image is quantized for pseudo halftone representation, and a predetermined dot pattern is embedded to the quantized image data. In this manner, the predetermined dot pattern can be added to the input image data such that the predetermined dot pattern is inconspicuous or the degradation of the original image can be reduced.

Abstract translation: 将输入图像数据的输入像素值转换为预定范围内的像素值，并将经转换图像的关注像素的像素值量化为伪半色调表示，并将预定点阵图案嵌入量化图像数据 。 以这种方式，可以将预定点阵图案添加到输入图像数据，使得预定点阵图形不显眼，或者可以减少原始图像的劣化。

Abstract: In a mechanical pencil, a tubular lead reservoir is connected to the rearward end of a lead chuck. A cylindrical weight is fitted slidably around the lead reservoir and is adapted to strike against the chuck to open the same to allow forward feed of the lead when a forward shake is applied to the pen barrel. In order to prevent forward feed of the lead as a result of unintended forward shake while carrying the pencil, a slider disposed rearwardly of the lead reservoir has a radially outwardly extending engagement projection which is adapted to slidably engage either a longitudinal guide slot in the pen barrel or a lateral slot circumferentially and rearwardly extending in the pen barrel. When the engagement projection is in engagement with the lateral slot, the chuck is caused to take an advanced position in which the chuck is open so that a forward stroke cannot feed the lead forward.
