An apparatus for growing a mixed compound semiconductor layer utilizing three or more source gases. The apparatus includes a horizontal type reactor chamber. The reactor chamber includes a partition plate separating an upstream region of the reactor chamber into an upper region and a lower region. The upper and lower regions are joined together forming a growth region in a downstream region of the reactor chamber. First and second inlet ports are provided at an upstream end of the lower region for admitting first and second source gases, respectively. A third inlet port is provided at an upstream end of the upper region for admitting a third source gas. An outlet port is provided at a downstream end of the growth region for exhaust. A substrate stage is arranged in the growth region so that the substrate surface is exposed to the growth region and forms a smooth surface for allowing a laminar gas flow.

A color printer for high-quality image recording. The printer comprises printer controller 200 having image memories (video RAM's) and printer engine 300. Memory selector 2005 changes over the image memory for forming image data by color component, and outputs a color designation signal CRCD indicative of a currently-used image memory. The CRCD signal value is '00' to indicate Y image memory 2001; '01', M image memory 2002; '10', C image memory 2003; and '11', K image memory 2004. Thus the CRCD indicates the color of the current image memory. Upon smoothing, VDO signal processor 302 changes over the smoothing logic based on the CRCD signal, accordingly, an appropriate smoothing logic for each color component image data can be applied.

Image processing apparatus and method for performing smoothing

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.

Image processing apparatus

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.

Image smoothing using selection among plural pre-stored pixel patterns

An information processing method includes inputting bit information, temporarily storing at least part of the input bit information, and detecting whether the stored bit information coincides with one predetermined feature of plural such predetermined features. Print information for an object pixel which corresponds to a stored bit is modified in a case where coincidence is detected. Modification may include, for example, contour retention in a case where a rectangular portion is detected, line width discrimination, or white line discrimination. In addition, second feature detection can determine that a right-angled portion is not involved, in which case print information is modified only if coincidence is detected with plural predetermined features and a right-angled portion is not detected.

Modifying print information based on feature detection

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.
