摘要： A method enables a dithered representation of an image to be converted to a continuous tone representation of the image. This undithering method compares the regions of dithered representation with sections of dither patterns to determine an appropriate continuous tone representation from which the dithered image could have resulted. When the continuous tone representation is found the region is converted into a continuous tone representation. This procedure may be spatially iterated on a pixel by pixel basis until all of the initial representation of the image is converted into a continuous tone representation. The procedure may also be modified to account for line art. Furthermore, the procedure may be applied to produce adjustments in the size of the picture including miniaturizations and enlargements of the original image. In accordance with this application, dithered portions of the original image are redithered in a manner to produce an alternative size output image. Similarly line art portions of the original image are treated as grey scale values and redithered to produce the alternative size representations of the line art.

摘要翻译：一种方法使得能够将图像的抖动表示转换为图像的连续色调表示。这种无抖动方法将抖动表示的区域与抖动图案的部分进行比较，以确定抖动图像可能产生的合适的连续色调表示。当发现连续色调表示时，该区域被转换为连续色调表示。该过程可以逐个像素地在空间上迭代，直到图像的所有初始表示被转换为连续色调表示。该过程也可以被修改以考虑线条艺术。此外，可以应用该过程以产生图像尺寸的调整，包括原始图像的小型化和放大。根据该应用，原始图像的抖动部分以产生替代尺寸输出图像的方式被重新排列。类似地，原始图像的线条部分被视为灰度值并且被重新排列以产生线条艺术的替代尺寸表示。

摘要： Disclosed is a method for controlling processes during printing. In order to determine the tint value (R) of a sector of a printing substrate, a digital image of said substrate sector is recorded, a frequency distribution of the grayscale values of the pixels is determined from said image, a minimum frequency is determined as a threshold value (GG)of the grayscale value in the central range of the grayscale value from said frequency distribution, and the pixels located on one side of said threshold value are counted as covered while the pixels located on the other side are counted as free so as to calculate the tint value (R) of the substrate. Also disclosed is an image-recording apparatus for recording images of different printing substrates on which the inventive method can be carried out. Said image-recording apparatus comprises an electronic camera module, an imaging lens that is disposed in front of said electronic camera module, and a device (3) for illuminating the substrate. Said illuminating device (3) encompasses both a bright field light source (4) and a dark field light source (6) which can be activated independently of each other and whose luminous intensity can be adjusted, respectively.

摘要： A printer for producing a printed matter of high image quality from printing data converted to one−bit data to shorten the data transfer time and transferred to the printer. A multinary−data creating section (23) converts CMYK color one−bit binary data from a developing section (22) into multinary data. A table is used which contains, as parameters, two−gradation data (0, 1) on the pixel of interest and values to which two−gradation data on the surrounding pixels of the pixel of interest, for example, the eight pixels on the left, right, upper, lower, and diagonal sides of the pixel of interest, is assigned to the places of a binary number of eight figures. The multinary−data creating section (23) sets, in the table, the values which the pixel of interest has to take on and which corresponds to the situation of the surrounding pixels. By referring to the table, two−gradation data is converted into multinary data.

摘要： An image descreening process first smoothes the image, where smoothing is accomplished by applying a convolution with a low pass filter (LPF) kernel, which is a parameter to the descreening function. Using the smoothed image, a determination is made for each pixel for which pixels around it participate in the modified filter. For a current pixel, a window is considered having the size of the LPF kernel, with the current pixel at the center. A threshold T1 which is given as a parameter, is used to mark the pixels in the current window. Considering a pixel in the window, if for all color components the difference between this pixel value to the center pixel value is less than T1 in absolute value the pixel is marked with a 1. Otherwise, the pixel is marked with a 0. Finally, an adaptive version of the LPF is applied. If the number of pixels marked with a 1 in the window is less than a third of the kernel size, the original pixel value is restored. Additionally, for a color component for which there is a small change in values within the original (non-smoothed) window (i.e. the difference between the maximal value to the minimal value in this component is less than another threshold T2), the value of this color component is restored. If these conditions do not hold, a new value for each component is determined. To be the convolution of the original window, the LPF kernel is masked with the 0/1 markings from the second step. That is, the modified convolution uses and adaptive kernel which is identical to the LPF kernel in the locations marked with one, but has zero entries in the locations marked with zero.
摘要翻译：图像去屏处理过程首先使图像平滑，其中通过应用与作为去屏函数的参数的低通滤波器（LPF）内核的卷积来完成平滑。使用平滑后的图像，对其周围的像素参与修改后的滤波器的每个像素进行确定。对于当前像素，窗口被认为具有LPF内核的大小，当前像素位于中心。使用作为参数给出的阈值T1来标记当前窗口中的像素。考虑到窗口中的像素，如果对于所有颜色分量，该像素值与中心像素值之间的差值小于绝对值T1，则像素用1标记。否则，像素用0标记。最后， LPF的自适应版本被应用。如果窗口中标记为1的像素数小于内核大小的三分之一，则恢复原始像素值。另外，对于原始（未平滑）窗口内的值有小的变化（即，该分量中的最大值与最小值之间的差小于另一个阈值T2）的颜色分量，该颜色分量被恢复。如果这些条件不成立，则确定每个组件的新值。要成为原始窗口的卷积，LPF内核将被第二步的0/1标记屏蔽掉。也就是说，修改后的卷积使用和自适应内核，它与标记为1的位置中的LPF内核相同，但在标记为零的位置具有零条目。
