摘要： A raster image processing system including a computer readable media storing digital information that includes information corresponding to an image, and instructions for performing raster image processing (RIP) using an over scan RIP technique on the image to generate a bitmap. Also included is a processor configured to RIP the image using the over scan RIP technique at a multiple of the desired output pixel resolution to produce a plurality of sub-pixels per output pixel. The processor is further configured to determine each image output pixel value based on the values set for the plurality of sub-pixels of each image pixel, by firstly comparing the values of the plurality of sub-pixels to each other and, and then secondly comparing the values of the plurality of sub-pixels to a set background value if needed. The processor then sets the output pixel value based upon that second comparison, and generates a bitmap.

摘要： An image processing method is disclosed. The image processing method includes the steps of detecting one or more dots near a step-shaped changing part of dots of which an outline part of a letter or graphics is composed, by using a reference pattern having a window size of “m×n” dots in which a number of dots “m” corresponds to resolution in the main scanning direction and a number of dots “n” corresponds to resolution in the sub scanning direction, converting the detected one or more dots near the step-shaped changing part that is nearly parallel to the main scanning direction into a dot whose size is smaller than that of dots of the step-shaped changing part, and not converting the detected one or more dots whose part is nearly parallel to the sub scanning direction.

摘要： An image processing system for providing edge enhancement of low resolution binary image files processes the low resolution bitmap data in sections or windows to determine whether an edge transition or "kink site" occurs within each window. The original bitmap data in the window is then replaced with edge enhanced gray scale data if a kink site is identified. The selection of the correct edge enhanced gray scale data to be used in place of the original bitmap data is based on whether the central pixel contained within the window is a black or white pixel, whether the central pixel is located on a single pixel line, and the location of the central pixel with respect to the kink site. The determination of whether the central pixel is a black or white pixel is based on the binary value assigned to the pixel, the determination of the location of the central pixel with respect to the kink site is based on pixel values and gradient magnitudes of surrounding pixel locations, and the determination of whether the central pixel is located on a single pixel line is based on the gradient magnitude of the central pixel and surrounding pixel locations.
摘要翻译：用于提供低分辨率二进制图像文件的边缘增强的图像处理系统处理部分或窗口中的低分辨率位图数据，以确定每个窗口内是否发生边缘转换或“扭结部位”。如果识别出扭结位置，则窗口中的原始位图数据将被边缘增强灰度数据替换。选择要用于代替原始位图数据的正确边缘增强灰度数据是基于包含在窗口内的中心像素是黑色还是白色像素，中心像素是否位于单个像素线上，以及中心像素相对于扭结位置的位置。确定中心像素是黑色还是白色像素是基于分配给像素的二进制值，中心像素相对于扭结位置的位置的确定是基于像素值和周围像素的梯度大小位置以及中心像素是否位于单个像素线上的确定是基于中心像素和周围像素位置的梯度大小。

摘要： A circuit to be used just prior to the printing engine to improve the image quality of a raster output scanner by modifying the darkness, size or shape of the spot. A buffer holds a window of n by n image pixels, and compares the bit pattern to a set of templates. For each match, a correction number is output, each correction number being a gray scale, duty cycle or bit pattern to be used to correct the center pixel of the current window. The comparison logic, instead of comparing the entire set of bits in the window to the templates, uses a number of small logic blocks in parallel, each comparing a subset of bits from the window. The output from this first set of comparisons is substantially reduced from the original set. This reduced set is now input to a second logic block which generates the final correction output bits. By using two stages, the first stage being a number of smaller logic blocks, the speed of the process is increased and the number of parts and the complexity of the circuit is reduced

摘要： An image data smoothing method smooths image data representing a picture transmitted by a facsimile transmitter and received by a facsimile receiver in the normal mode in printing out the image data so that curves and oblique lines of the picture are reproduced satisfactorily. The image data smoothing method comprises steps of determining an objective changing picture element on an objective image data line, determining changing picture elements on a precedent image data line precedent to the objective image data line, and a subsequent image data line subsequent to the objective image data line, producing a correction image data line by reversing a predetermined number of picture elements on the objective image data line determined on the basis of the positional relation between the changing picture elements and continuous with the objective changing picture element, and inserting the correction image data line between the objective image data line and the subsequent image data line in printing out the image data on the successive image data lines.

摘要： A method and apparatus for displaying enlarged or enhanced dot matrix characters is disclosed. Using stored sets of binary data elements which define the shape of the respective characters of a set, logical operations are performed to add additional binary data elements to provide the desired enlarged character. Characters may be enlarged in the vertical and horizontal directions by lengthening the horizontal, vertical, and diagonal linear components which together comprise the character. Characters may also be enhanced by thickening the linear components thereof in a direction orthogonal to that of the linear components, and made more dense with additional dots along the length of the linear components. The stored data defines the character with a high density in the horizontal direction and a lower density in the vertical and diagonal directions. The characters are enlarged, and enhanced, by defining a reference matrix which comprises a subset of the stored binary data elements, expanding the reference matrix by adding blank binary data elements to the defined reference matrix at locations between the stored binary data elements, and comparing portions of the expanded reference matrix with corresponding portions of a predetermined matrix, and converting to a dot those added binary data elements that match the elements of the predetermined matrix. Characters may be differentially enlarged, or enhanced in one manner but not another, or they may be thickened toward the middle of each character.
