摘要:
An electrophotography apparatus prevents the edge effect without causing the blurring or loss of a single-dot image or a single-dot-width line. Based on a measurement of a testing patch, two templates with different sizes are generated. Image data to be printed is subjected to template matching using the templates to obtain a difference region as an image edge region of the image data where, when the image data is developed, the amount of attached toner is increased. The exposure amount for the image edge region is controlled based on a measurement of the amounts of attached toner in edge portions of the testing patch so that the difference in the attached toner amounts are minimized.
摘要:
A reagent dispensing mechanism (15), first and second dispensing-mechanism transfer means (26, 27), and a second reagent vessel (reagent cassette) carrying-in/out mechanism (24), which are constructed by employing an XY-mechanism, are arranged so as to travel above a reagent table (25) to carry in/out a reagent cassette (22). As compared with the case where the reagent cassette carrying-in/out mechanism (24) is installed radially of the reagent table (25), the area of an automatic analyzer in the horizontal direction can be reduced and a reagent vessel (16) can be moved to a predetermined position in a shorter time by combining the rotation of the reagent table (25) with the movement of the XY-mechanism. Further, as compared the case of dispensing reagents from reagent vessels in a matrix pattern by using the reagent dispensing/transferring mechanism, the travel distance of the transferring mechanism can be shortened and so can be the travel time. Thus, an analyzer adaptable as a machine of high processing capability with a shorter cycle time can be constructed.

An image processing apparatus for a laser printer, wherein a halftone control through laser pulse modulation (PWM) is used in combination with distributed clustered-dot halftone processing which distributes a tone level over four clustered-dots, and the value represented by higher bits of a threshold are used to switch a PWM pulse pattern in a highlight area to a discontinuous pattern, thereby implementing the high density halftone processing, which provides a high highlight tone density and stability, only with a small scale memory and circuit.
摘要:
A raster device such as a digital printer or the like which sequentially compares input image data with each element in a threshold matrix to convert the input image data into binary or multi-level pixel data. For providing both a higher resolution and a larger number of halftone levels for an output image at a low cost, an input image is decomposed into four color planes as CMYK data, and data on each color plane is compared with a dither matrix in a binarization circuit to be converted to binary data. The dither matrix generates a dither pattern composed of eight clusters having substantially the same shape as a kernel cluster capable of expressing 15 or more halftone levels. In this way, a smooth gradation having 120 or more halftone levels is realized by repetitively applying a small pattern having approximately 15 halftone levels.
摘要:
In an elastic frictional member including: a core ring fitted on a sleeve fixedly mounted on a shaft; and an elastic element engaged with the outer cylindrical surface of the core ring, a plurality of small protrusions are extended from the outer surface of a lip forming a part of the elastic element; that is, from a slide surface of the elastic element which is in slide contact with the inner cylindrical surface of a shaft hole formed in the gear. The small protrusions of the lip are in point contact with the inner cylindrical surface of the shaft hole of the gear; that is, the outer surface of the lip from which the small protrusions are extended is spaced from the inner cylindrical surface of the shaft hole of the gear, thus allowing the formation of a lubricant film in the space. The lubricant film thus formed maintains the friction coefficient substantially constant.

A color management system is provided that includes a color transformation unit that uses a profile connection space to perform a color transformation process on input image data based on an input side color transformation parameter associated with the input image data for translating an input device-dependent color value that describes the input image data into a device-independent color value of the profile connection space and an output side color transformation parameter for matching the device-independent color value to an output device-dependent color value. The color management system further includes an output device selection unit that enables a user to select at least two output devices from plural output devices that are available for selection, and a profile connection space generation unit that automatically generates the profile connection space according to a predetermined profile connection space generation method based on the gamuts of the output devices selected by the user.
