摘要： If the width of a rectangle to be drawn by a drawing command is less than or equal to a first reference value that is previously determined dependently on the length of one record of cache memory, the drawing command for the rectangle is held in a rectangular drawing command storage area in a RAM. If several rectangles held in the rectangular drawing command storage constitute a lateral-direction gradation pattern, a drawing command group that draws the rectangles is converted into a secondary drawing command that repeatedly draws in an auxiliary scanning direction a virtual-image of one line that constitutes the lateral-direction gradation pattern and that extends in the main scanning direction. There is no need to overwrite the record in the cache memory while generating drawing data based on the secondary drawing command because the width of the virtual-image is less than or equal to the width of one record in the cache memory.
摘要翻译：如果由绘图命令绘制的矩形的宽度小于或等于先前根据高速缓存存储器的一个记录的长度确定的第一个参考值，则矩形的绘制命令保存在矩形图中 RAM中的命令存储区域。如果保存在矩形绘制命令存储器中的若干矩形构成横向渐变图案，则将绘制矩形的绘图命令组转换为辅助绘制命令，该辅助绘制命令在辅助扫描方向上重复绘制构成的一条线的虚拟图像横向渐变图案，并且在主扫描方向上延伸。由于虚拟图像的宽度小于或等于高速缓冲存储器中的一个记录的宽度，所以不需要根据辅助绘制命令来生成绘制数据，从而覆盖高速缓冲存储器中的记录。

摘要： An electrostatographic recording method for printing an image on a receiver comprising the steps of: operating a primary charger to establish a uniform primary voltage level on an image recording member; developing a control patch on the image recording member, measuring density of the control patch to thereby provide a density measurement signal; converting the image into a digital bitmap comprised of an array of pixels wherein each pixel is assigned a digital value representing marking information; rendering the digital bitmap by defining each pixel as either a background pixel, interior pixel, or an edge pixel and reassigning the digital value of one or more of edge pixels or interior pixels independently and as a function of the density measurement signal; modulating electrostatic charge on the image recording member as a function of the digital bitmap after rendering.

摘要： A method for printing digital image data onto light-sensitive material, such as photographic paper, is disclosed. The image data to be reproduced are received at a reader station, an exposure correction is applied to the image data in a computing station, and the exposure-corrected data are printed onto the light-sensitive material by means of a printer module. The image data are corrected during the exposure correction in a manner that is both specific for the type of light-sensitive material used as well as for the image data. A printing over-exposure may be compensated during image output by the combination of these two dependencies during correction of the image data.

摘要： When the image data having a predetermined gradation value for each pixel is input, and the image data is searched from the initial pixel and the total of the gradation values of the pixels, including the searched pixels, becomes a predetermined threshold value or more, a dot is generated at the center of the gravity position as a quantized pixel group. In the searching, an unprocessed pixel closest to the center of gravity position, including this pixel, is selected. If there are a plurality of unprocessed pixels, selection is performed at random. For the pixel selection, a pixel closest to the center position computed from the positional coordinates may be selected, rather than the center of gravity. Also a dot may be generated at the center position of the quantized pixel group.

摘要： A system and method are provided for correcting printed color and tone of a library of similar digital images. A single image is selected from a library of similar images, and manipulated with a set of unique transformations. Each of the manipulated images is processed for printing. Printer settings for actual job data are identified, and multiple reproductions of the selected image are printed at the identified printer settings for the job. Optimum transformations are determined by visual inspection of a full array of images, each of the full array of images having been manipulated by a different transformation prior to printing.

摘要： The present invention provides for a method of adjusting the gray scale response of a first scanner and a second scanner so that the two gray scale responses more closely match one another. The method includes the step of providing a first scanner that has a gray scale response upon scanning a target. Also, a second scanner is provided that has a gray scale response upon scanning the target that is adjustable. The gray scale response of the first scanner is measured upon the scanning of the target. Also, the gray scale response of the second scanner is measured upon scanning the target. Additionally, the gray scale response of the second scanner is adjusted in order to more closely match the gray scale response of the first scanner.

摘要： A grayscale patch is formed using a uniform density signal on the entire surface of a recording paper sheet corresponding to a print region of a photosensitive drum, and a plurality of such grayscale patches corresponding to different gray levels are output (S3501). The entire surface of each of the plurality of output grayscale patches is scanned by a scanner unit to obtain luminance data for respective pixel positions (S3502). The scanned luminance data for the entire surface are converted into reflection density values using a predetermined table (S3503), and a two-dimensional null correction LUT corresponding to the print region is obtained on the basis of the converted density values (S3504).

摘要： In a black character detection processing, RGB data read from a line buffer is converted into YIQ data. For a subject pixel, a subject area centered on the subject pixel is set, and a judgment pixel that has the lowest brightness in the subject area is set. Then, a judgment area is set as being centered on the judgment pixel. If the absolute values of the averages of chroma components I and Q in the judgment area are both less than the corresponding thresholds T1 and T2, the subject pixel is determined as being an achromatic pixel. Black codes are added to fine-line pixels and edge pixels if the fine-line pixels and edge pixels are determined as being achromatic. Thus, the fine-line pixels and edge pixels can be specified as to be printed in black monochromatic ink. Therefore, black character or similar fine-line or edge part images can be outputted with high quality.
摘要翻译：在黑色字符检测处理中，从行缓冲器读取的RGB数据被转换为YIQ数据。对于被摄体像素，设置以对象像素为中心的被摄体区域，并且设定在被摄体区域中具有最低亮度的判断像素。然后，判断区域被设置为以判断像素为中心。如果判断区域中的色度分量I和Q的平均值的绝对值都小于对应的阈值T1和T2，则将被摄体像素确定为无彩色像素。如果细线像素和边缘像素被确定为消色差，则黑色代码被添加到细线像素和边缘像素。因此，细线像素和边缘像素可以被指定为以黑色单色墨水印刷。因此，可以高质量地输出黑色字符或类似的细线或边缘部分图像。
