    摘要: This disclosure relates to an image forming and processing apparatus having a plurality of storage devices 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 which generates an output image based on inputted print data, includes a resolution converting device which converts image data corresponding to the inputted print data at a first resolution into image data having a second resolution. The image conversion device includes a plurality of arithmetic processing units each of which performs computations which differ from the others, with one of the plurality of arithmetic processing unit being selected in dependence upon a recording density set for recording the output image. In other aspects, the resolution conversion computation can be input into the device from an external device. In situations where the generated output image is recorded on a pulse-width-modulated device, such as a laser beam printer, it is possible to control the pulse-width based on the density set for recording.

    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: 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.
