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： On the basis of inputted multivalued image data, direction of growth is decided from a density pattern having a plurality of growth directions and a density pattern is caused to grow based upon the growth direction that has been decided. As a result, character images are formed sharply and high-quality half-tone images exhibiting reduced density irregularity can be produced.

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： 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： The present invention is structured in such a manner that, when multivalued pixel data which constitutes a multivalued image are supplied, a predetermined number of interpolated pixel data are generated and inserted between the supplied and successive pixels. At this time, the gradient of each of the interpolated pixels is calculated and determined in accordance with the gradient of the supplied neighboring multivalued pixels. Thus, the image is recorded on a recording medium in accordance with image data including the interpolated pixel. As a result, print information processed so as to be printed by a low resolution printer can be printed with the same size and high quality as when printed by a high resolution printer according to the present invention.
