摘要： A color image printing apparatus prints one pixel by superposing a predetermined dots of three colors within a 3.times.3 dot matrix in accordance with a density of the pixel. The positions of the printed dots within the dot matrix are stored as a dot pattern for each color. One dot pattern is used for each of a plurality of densities included in one density range. The printing energy for each of the dots included in the dot pattern is controlled in accordance with the density level of the pixel. The dot pattern is different for each color and three dot patterns are stored for each color and for each density range. These three dot patterns are repeatedly used for every three pixels which are continuous in the horizontal direction. These three dot patterns have two or three texture directions. The texture direction other than the vertical direction is different for each color.

摘要： An apparatus for printing images on a booklet comprises, first and second paired pinch rollers for conveying pages of the opened booklet to a printing head, located between these paired pinch rollers, a rotatable platen opposed to the printing head and located between the paired pinch rollers, guide plate for guiding one page of the opened booklet to the platen, and a press member for fixing the free end of the one page to the platen. The second paired rollers hold the other page of the booklet but may slipe the page when the free end of the one page is fixed onto the platen thereby adding tension to the other page of the booklet as the platen is rotated. The layout of the recorded images are changed and then printed on the page.

摘要： An improved thermal recording head having a large number of heating elements connected in parallel between a plurality of pairs of electrodes for recording halftone images is provided. Each of the heating elements has end portions divided into two leg sections, and the center portion is narrowed. This configuration allows the thermal recording head to reduce image-roughness to the naked eye. In addition, the variable range of recording density can be significantly expanded.

摘要： A color multi-function type copying machine is disclosed which includes an image input unit for optically sensing an input image and generating an image signal. A function memory stores an ink color used in a color frame to be written in the input image in order to designate its partial image region and a specific image edit function assigned to the ink color and desired to be executed by an operator so that the ink color and the specific image edit function can be rewritten. When a closed loop-like color frame of a selected color is written in the input image, a color frame region detecting unit detects a shape and a color of the color frame. In response to the detection result, the memory is accessed to determine an image edit function corresponding to a first selected ink color of the detected color frame. A color edit unit executes one or a plurality of image signal processing corresponding to the determined image edit function for the input image signal. The edited image signal is supplied to a color printing unit via a signal processing unit and is reproduced therein.

摘要： A halftone image printing device represents an image using a pixel matrix, prints each pixel as a dot pattern constituted by predetermined dots in a dot matrix, and controls the dot pattern and the printing density (multilevel density) of each dot included in the dot pattern in accordance with the density (multilevel) of the pixel. An overall printing density range is divided into four density ranges, i.e., from the lowest to the highest density ranges, and each pixel is defined by a 3.times.3 dot matrix. A dot pattern in the lowest density range has a dot at the center of the matrix, a dot pattern in the next lowest range has dots at the center of the matrix and at positions above and to the right of the center, a dot pattern in the next highest density range has dots at the center of the matrix and at positions above, below, and to the right and left of the center, and a dot pattern in the highest density range has dots at the center of the matrix and at positions above, below, to the right, left, and upper right of the center. In order to print each dot at each density level in each density range, the level of energy supplied to the heating element of the thermal head corresponding to each dot is precisely controlled.

摘要： A halftone image printing device for printing an image consisting of picture elements arrayed in a zig-zag fashioning. Each picture element is composed of dots forming a quasi-diamond-shaped matrix. The dot matrix is a 2 (row) x 3 (column) matrix with two additional dots located at the top and bottom, respectively. The range of optical density, within which the densities represented by the picture elements fall, is segmented into sub-ranges. Different heating-resistors are assigned to each sub-range of density. The dots printed by the heating-resistors assigned to any sub-range of density forms a "dot pattern" of a specific shape. The first dot pattern has one dot printed on the upper-central part of the rectangular matrix. The second dot pattern has three dots forming an L-shaped pattern, the first dot printed on the upper-central part of the matrix, the second dot printed above the first dot, and the third dot printed to the right of the first dot. The third dot pattern consists of five dots forming a cross, the first dot printed on the upper-central part of the matrix, the second dot printed above the first dot, the third dot printed to the right of the first dot, the fourth dot printed below the first dot, and the fifth dot printed to the left of the first dot. And the fourth dot pattern consists of five dots forming a cross and an additional dot printed immediately below the cross. Of the dots of each dot pattern, the dot on which energy concentrates more than any other dot assumes the same location for all dot patterns.

摘要： A half-tone image reproduction apparatus, which comprises a Dither matrix memory, constituted by a plurality of elements, for storing a multi-level Dither matrix having multi threshold levels assigned to the individual elements, input data supplying means for supplying the element on the Dither matrix and an input density level, and print dot forming means for forming print dots in accordance with the energy control level selectively read out from the Dither matrix memory. The energy control level stored in the Dither matrix memory is set in accordance with rules for changing the energy control level in accordance with a change in input density level. These rules are independently suitably determined for the respective partial density ranges which constitute a whole density range for the input density. According to this invention, gradation jump and deformation at a high density region can be prevented so that a half-tone image with smooth gradation and high resolution can be attained.
