摘要： An image forming apparatus and method produce, when 600 dpi image data is generated from 300 dpi image data, interpolated data of a pixel of interest by a two-value logical operation in a case where the image data about the periphery of the pixel of interest appertains to binary representation. When the image data is judged to appertain to an image of multivalued representation, the interpolated data of the pixel of interest is produced by a numerical operation. As a result, a 600 dpi picture of the same size can be printed and recorded in such a manner that outline sharpness and smoothness, which are characteristics possessed by a two-value image, are maintained at portions of the input 300 dpi image data that are two-value images while smoothness of the grayscale is maintained at portions of the input 300 dpi image data that are halftone images.

摘要： This disclosure relates to an image forming and processing apparatus having a plurality of storage device capable of forming an image at a high speed by reading image data in parallel. Since a predetermined quantity of image data is stored in a plurality of hard discs, and the image data is read from the hard discs to a double buffer in parallel, an image can be formed continuously at a high speed. Another structure is arranged in a manner such that images are stored in hard discs of an optional number and the images are transmitted to a printer engine by using a FIFO (First In First Out) buffer which corresponds to the hard discs. Therefore, an image can be transmitted continuously at a high speed asynchronously with the printer output.

摘要： An image processing apparatus where plural line memories store first image information corresponding to a first recording density based on input image data for plural lines, and a logical circuit included in a decision circuit determines a pixel data to be interpolated corresponding to the pixel position of second image information when the first image information is converted to the second image information in accordance with the stored first image information for plural lines. A logical circuit also included in the decision circuit detects an predetermined pattern in accordance with the stored image information for plural lines when the pixel data to be interpolated is determined, calculates a logical expressions for predetermined pattern diffusing processing, and determines a value of the pixel to be interpolated to diffuse the predetermined pattern in the second image information. With the above structure image information for a lower recording density is converted to information for a higher recording density, where half-tone images in high quality can be obtained.

摘要： An information recording apparatus for recording a color image with improved resolving power and image quality is disclosed. Color image data are temporarily stored in a memory and compared with predetermined patterns in a wide reference area. If they coincide, indicating the presence of a contour of a pattern, an object pixel is modified to finer dots, in order to smooth the contour. There are also provided patterns indicating the features of dither images, in order to identify whether the color image data correspond to such dither image, and to avoid erroneous smoothing process that deteriorates the image quality of such dither image.

摘要： This invention provides an information recording apparatus, which can save the consumption amount of a toner without thinning out an image in units of pixels, and can realize smoothing processing with high image quality. In input data, a pixel corresponding to an edge portion is subjected to smoothing processing. Data of a black pixel which is not subjected to smoothing processing is recorded while saving toner by controlling the print pulse width or the print pulse number upon recording of the black pixel on the basis of a print density command.

摘要： When a multiple-color image is printed by electrophotography unwanted spaces are produces between different colors. These spaces are attributed to non-development of toner caused by the influence of an electric field at the boundary of an electrostatic latent image formed on a photosensitive drum. Accordingly, when data conversion is converted from two-bit data of a bitmap to eight-bit data that are used for modulating a light signal, a pixel of interest and the neighboring 9×9 pixels are stored and the state thereof is determined. If the pixel of interest is a white pixel and the neighboring pixels are all non-white pixels, then the pixel of interest is not left at a value corresponding to white, but is converted to a value corresponding to a potential that will not develop toner. The photosensitive drum is irradiated with a laser based upon the data resulting from the conversion. Thus, a sudden conversion from a potential corresponding to white to a potential corresponding to the maximum density is eliminated at the outline of the image. This makes it possible to prevent the influence of an electric field at the edge of the image and, hence, to prevent the occurrence of unwanted spaces between colors.
摘要翻译：当通过电子照相打印多色图像时，不同颜色之间产生不需要的空间。这些空间归因于由在感光鼓上形成的静电潜像的边界处的电场的影响引起的调色剂的不显影。因此，当将数据转换从位图的2位数据转换为用于调制光信号的8位数据时，存储感兴趣像素和相邻9×9像素，并确定其状态。如果感兴趣像素是白色像素，并且相邻像素都是非白色像素，则感兴趣的像素不会保持在与白色相对应的值，而是被转换成对应于不会显影调色剂的电位的值。基于转换得到的数据，用激光照射感光鼓。因此，在图像的轮廓处消除了从对应于白色的电位到对应于最大密度的电位的突然转换。这使得可以防止图像边缘处的电场的影响，并且因此防止颜色之间出现不想要的空间。

摘要： A color image processing system outputs data to a color image forming unit for forming a color visible image by overlapping a plurality of color developers. The color image processing system includes a print data receiving unit that receives print data, a bitmap data producing unit that produces bitmap data having colors that correspond to the plurality of color developers from the print data, a data size determining unit that determines a data size of the bitmap data, and a degrading unit. When the data size determined by the data size determining unit is greater than a predetermined size, the degrading unit produces bitmap data having fewer colors, wherein a predetermined color is removed from the colors corresponding to the plurality of color developers.
