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： 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： A half-tone image recorder in which input digital data is represented by a plurality of bit data for each pixel. A data conversion device outputs digital data indicative of a recording-start position and a recording-end position, based on the input digital data. A recording device such as a laser printer records an image in accordance with the output digital data from the data conversion device. The data conversion device controls a first value of the digital data indicative of the recording-start position and a second value of the digital data indicative of the recording-end position so as to change a black-area growing direction within one pixel in the recorded image. This results in the recordation of a high-quality half-tone image without conspicuous vertical stripes and without conspicuous white stripes in the main-scanning direction of the recording device due to pitch irregularity.

摘要： A full-color printer which reduces toner consumption by lowering the overall image density without changing the overall image tonality. An invalid data masking unit 31 masks non-printing area of a image signal 39 outputted from a FIFO buffer 30, and outputs the masked image data into a toner-saving image converter 32. The toner-saving image converter 32 zigzag masks the image signal every other pixel in main-scanning and subscanning directions based on a toner-saving mode designation signal A from a CPU 38. The masked image signal density is "00[H]". Thereafter, a .gamma. corrector 35 .gamma. corrects the masked image signal, and a PWM 36 performs pulse-width modulation on the .gamma.-corrected image signal. Image output is made by driving a semiconductor laser 120 with the pulse-width modulated signal.
