摘要： An image processing apparatus includes a binary-coding section, a removing section and a signal generating section. The binary-coding section binary-codes a plurality of color component signals color by color. The removing section removes minor color components from the color component signals, and the generating section generates record color signal by using both a color component signal left after removing the minor color components and the color component signals before binary-coding.

摘要： There is provided an image processing apparatus such as facsimile apparatus or digital copying machine for digitizing image data into two values or multi-values. The apparatus comprises: an input device to input data of a target pixel to be digitized; a calculating circuit to obtain an average density value of a predetermined region; a digitizing circuit such as a binarizing circuit for digitizing or binarizing the target pixel data on the basis of the average density value obtained by the calculating circuit; and a correction circuit to correct a difference which occurs upon digitization by the digitizing circuit. The calculating circuit calculates the average density value m.sub.1 of the pre-determined region when the target pixel data was binarized to 1 and the average density value m.sub.2 of the predetermined region when the target pixel data was binarized to 0 by using a predetermined weighting mask. The digitizing circuit binarizes the target pixel data by using (m.sub.1 +m.sub.2)/2 as a threshold value. When the difference between the target pixel data and the average density value is within a predetermined value, the difference is corrected, so that an image of excellent gradation can be reproduced. When it is equal to or larger than the predetermined value, the difference is not corrected, so that the resolution of a character portion such as an edge portion can be improved.
摘要翻译：提供了一种图像处理装置，例如用于将图像数据数字化为两个值或多值的传真装置或数字复印机。该装置包括：用于输入要被数字化的目标像素的数据的输入装置; 获得预定区域的平均密度值的计算电路; 数字化电路，例如二值化电路，用于根据由计算电路获得的平均密度值数字化或二值化目标像素数据; 以及校正电路，用于校正由数字化电路数字化时发生的差异。当目标像素数据被二进制化为1时，计算电路计算预定区域的平均密度值m1，并且通过使用预定加权掩码将目标像素数据二值化为0时的预定区域的平均密度值m2计算。数字化电路通过使用（m1 + m2）/ 2作为阈值对目标像素数据进行二值化。当目标像素数据和平均浓度值之间的差值在预定值内时，校正差异，从而可以再现优异灰度的图像。当其等于或大于预定值时，差异不被校正，从而可以提高诸如边缘部分的字符部分的分辨率。

摘要： In an image processing apparatus in which digital data of a certain number (m) of levels are converted into digital data of a larger number (n) of levels, then subjected to certain desired editing processing, and again digitized to data of the original number (m) of levels. The redigitization to m levels is conducted by determining the average density of a predetermined area, utilizing data of pixels already redigitized to m levels, and redigitizing the data of n levels into m levels, utilizing the average value. This process significantly reduces the amount of data processing required without formation of an unpleasant texture on the image resulting from errors in digitization.

摘要： There is disclosed an image processing apparatus for intermediate tone processing of an image signal into a binary signal, capable of providing a reproduced image with excellent resolution and gradation with a simple structure, and without the periodic texture inherent to the conventional error dispersing method or average density conserving method. The disclosed apparatus determines the average density of an already binarized predetermined image area, binary digitizing the image signal of a contemplated pixel, utilizing the determined average density as the threshold value, and distributing the error, generated in the binary digitization, to the image data of plural pixels to be digitized thereafter with certain distribution factors. The distribution factors are randomly changed according to random numbers generated by a generator, so that the reproduced image is free from periodic patterns resulting from periodic distributions of the errors.

摘要： The present invention includes: a step of creating at least a play list including reproduction start times of the display terminal devices (1) and acquisition destination data indicating acquisition destinations of the creative data; and a step of transmitting the play list and the creative data to the display terminal devices (1) via the normal relay server devices (30) and the super relay server devices (20). The play list creating step creates the play list by determining the acquisition destination data in such a manner that the creative data is distributed preferentially to the super relay server devices (20) rather than to the normal relay server devices (30) and that the normal relay server devices (30) acquire the creative data from the super relay server devices (20). Because of this, the load on distribution devices for distributing creative data is reduced.
