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： When binary image data is outputted from a FIFO buffer, a first black pixel counting circuit counts black pixels in a 3.times.3 matrix having a target pixel at its center to produce a count value BK2. Similarly, a second black pixel counting circuit counts black pixels in a 17.times.9 matrix to produce a count value BK1. Based on the count values BK1 and BK2, a value indicating the dot diameter is outputted from the output value table while a look-up table and the output value table are sequentially referred to. Setting is so made that the dot diameter becomes smaller as the count values BK1 and BK2 decrease.
摘要翻译：当从FIFO缓冲器输出二进制图像数据时，第一黑色像素计数电路对其中心具有目标像素的3×3矩阵中的黑色像素进行计数，以产生计数值BK2。类似地，第二黑色像素计数电路对17×9矩阵中的黑色像素进行计数以产生计数值BK1。根据计数值BK1和BK2，依次参考查询表和输出值表，从输出值表输出表示点直径的值。如此设定使得随着计数值BK1和BK2的减小，点直径变小。

摘要： Binary data (VDO) developed to a dot pattern are sequentially stored in line memories (1-9). A processing circuit (43) is constituted by a logic calculation circuit, and determines an edge portion of an image or a halftone image on the basis of 11.times.9 pixel data in shift registers (34-43). When the edge portion of an image is determined, data of a pixel of interest is converted to data that can print a smooth edge portion. Changed data (VDOM) is converted again according to the type of toner. The converted signal is supplied to a laser driver of a printer, and a printing operation is performed by scanning a laser. A resolution setting unit (1700) receives a resolution setting command from an external apparatus (1300), and sets a designated resolution in a printer (1200) according to the resolution setting command. The resolution setting unit (1700) divides one pixel into an optimal number of pixel sections on the basis of the designated resolution, and sets a logic circuit for performing optimal smoothing processing for divided data in a smoothing unit (1018). Bit map development based on code data supplied from the external apparatus (1300), and smoothing processing according to a smoothing logic, are performed.

摘要： An image processing apparatus includes a window setting device for setting a portion of a written region of an image composed of dots in an orthogonal matrix as a window, and for moving the set portion within the written region. A first edge detecting device serves to detect differences between image data of a given dot in the window set by the window setting device and image data of dots neighboring the given dot, and serves to detect directions of the detected differences. A second edge detecting device serves to detect edges between neighboring dots other than the given dot, the detected edges relating to image data differences and image data difference directions respectively equal to the image data differences and the image data difference directions detected by the first edge detecting device. A calculating device serves to provide the edges, detected by the second edge detecting device, with predetermined coefficients respectively, and serves to add the predetermined coefficients for the edges detected by the second edge detecting device to calculate a sum of the predetermined coefficients. A signal generating device serves to generate an image signal which varies a size of the given dot in accordance with the sum of the predetermined coefficients which is calculated by the calculating device.

摘要： A method and system for efficiently generating grayscale character fonts from bi-level master character fonts decomposed into rectangles. For each filter array to be used for converting master character fonts into grayscale characters there is generated at least one summed area filter array. Each element in each summed area filter array represents the sum of the filter array elements in a corresponding subarray of the filter array. A grayscale character is generated by performing, for each rectangle in the corresponding decomposed master character, the steps of:specifying a filter array, and its corresponding summed area filter arrays;determining the pixels in the grayscale character affected by the rectangle and a set of corresponding sampling points located inside and near the rectangle;for each grayscale character pixel affected by the rectangle, performing the steps of:assigning the pixel a predefined value corresponding to a black pixel if the corresponding sampling point is located inside the rectangle, and is offset from the perimeter of the rectangle by at least one half of the extent of the filter's support; and otherwiseadding to the value of the grayscale pixel a value from the summed area filter array corresponding to the intersection of the selected filter array, centered at the sampling point corresponding to the grayscale pixel, and the rectangle.

摘要： A misalignment compensation technique for a dot printer is disclosed. This technique first supplies printing instructions to a printhead for energizing printing elements in various groups (primitives) to print a pattern on a medium. The printed pattern is then detected by optical sensors in the printer. Based on the detection, a position offset error for each primitive is determined. These errors are used to generate a separate time correction for each of the primitives such that, when the printer is used normally, the time period for printing a dot will be advanced or delayed for each primitive so as to align the dots printed by the primitives. In another embodiment, alignment data taken by a manufacturing line sensor is stored in a memory on the print cartridge. After the print cartridge is installed in the printer, a second optical test completes the data needed to create timing correction values.
