摘要： Curve information is set in accordance with curving of a scanning line that occurs when an image is formed. A value of a target pixel is corrected on the basis of image data that is provided in a reference window having the target pixel and peripheral pixels, thereby transforming a region having a color of a specified image. The reference window that is used in the transformation is corrected in accordance with the curve information with respect to a main scanning position for pixels that are to be processed.

摘要： An image forming apparatus includes an image forming unit, image formation control section, counter, image formation condition regulation section, controlled printed-paper number storage section, and regulation control section. The image forming unit includes a plurality of functional sections. The counter counts a cumulative printed-paper number in a series of image formation processing. The image formation condition regulation section regulates an image formation condition of at least one of the functional sections. The controlled printed-paper number storage section stores a benchmark printed-paper number and first allowable value to determine the timing of regulating the image creation condition. The first allowable value is set to be less than the benchmark printed-paper number. The regulation control section activates the image creation condition regulation section after the series of image formation processing when the cumulative printed-paper number is equal to or greater than the first allowable value after the series of image formation processing.

摘要： In an image forming apparatus for forming a color image by superposing component color images, a control device obtains position data representing a forming position of each of plural registration mark images for the component color images with respect to a positional reference value arbitrarily determined, divides the position data into each of a unit reference range representing a range in which one mark image is formed, converts the position data divided for each unit reference range into those based on respective reference values representing the front edge of the unit reference ranges, extracts the position data representing ranges common to the mutually overlapping ranges each of which is represented by a couple of position data corresponding to the rising and falling edges of a passage timing pulse as read position data of the mark image of the component color, and calculates the amounts of positional deviations of the component color images from one another on the basis of the position data extracted.

摘要： What is disclosed is a novel system and method for minimizing visual artifacts, such as ROS skew and laserbeam bow, in a brick-layer halftone structure. The present method involves determining a line pattern from ROS skew and laserbeam bow profiles which traverses through successive halftone cells displacing pixels along scanlines in the process direction. The amount of displacement is varied as a function of the cross-process location as determined by the line pattern. Pixels along scanlines are shifted in a direction defined by the error profiles. In each halftone cell within which the line pattern traverses, extra pixels (empty pixel spaces created in the halftone cell by the shifting operation) are filled with lost pixels (pixels bumped from the halftone cell during the shifting operation) such that overall density of the halftone cell is maintained. The lost pixels are buffered such that lost pixels are preserved.

摘要： An image forming apparatus including plural image forming units arranged for respective color components at predetermined intervals. A transportation unit transports a recording medium to the plural image forming units. A delay memory delays sending of image data for a time required to transport the recording medium between the plural image forming units. A length holding unit stores, for each page, plural pixel counts, the pixel counts representing respective numbers of pixels in rows of pixels spaced in the sub-scan directions, which pixels represent the image data for image formation. A reading control unit controls reading of the image data stored in the delay memory on the basis of the pixel counts of each page stored in the length holding unit.

摘要： An image forming apparatus capable of minimizing degradation in density correction as a part of skew correction includes a noise-occurrence determining unit, a correction-target-pixel selecting unit, a density correcting unit, and a phase correcting unit. When the noise-occurrence determining unit determines that noise would appear, the density correcting unit performs density correction on a correction target pixel that is determined by the correction-target-pixel selecting unit. The phase correcting unit corrects an output point in time of image data of the density-corrected correction target pixel in a pixel period during which the image data can be output so as to output the image data at a position displaced away from a shift position or toward a shift position.

摘要： An image forming apparatus capable of decreasing the image unevenness of a superimposed image at the time of forming starting (head) lines of the images in respective colors with different beams in order to decrease a shift of a superimposed image. Let a position, where an image in a first color is formed with a beam A as a leading beam, be (a). Let a starting position of formation of an image in a second color be (b), and one dot (line) of shift arises in the superimposed image. In order to decrease the shift of the superimposed image, image formation is performed with selecting a beam B as a beam which writes a head of the image (c). When image formation is performed for color shift reduction with changing a leading beam for each color image, tonality correction is performed to each beam for subsequent images so as to decrease image unevenness due to the difference between shapes and exposure power of respective beams.

摘要： An image forming apparatus capable of accurately compensating an increase or decrease of a toner area coverage resulting from shifting that is performed to correct skew is provided. A color density of image data represented by a correction target pixel is corrected such that the increase or decrease in the toner area coverage on the correction target pixel is compensated excluding a toner area coverage on the correction target pixel covered by a toner image that would be formed based on a color density of image data to be represented by a neighboring pixel of the correction target pixel. This effectively reduces banding noise on an output of the image data and prevents degradation in image quality.

摘要： A color image forming apparatus is provided that forms an image by correcting registration shifts during an image forming process by using image data and which prevents toner from being blown away and scattered during a fixing process by thinning pixels without making an erroneous decision. When multivalued color image is binarized, the threshold is corrected by using information on grayscale level correction. Further, when trailing phenomenon prevention operation is performed on the binarized image data, the patterns to be used for pattern matching are changed and selected according to whether the subscan direction line shifting point lies within the reference window.
