摘要： PROBLEM TO BE SOLVED: To provide an image processing apparatus which can avoid such a problem that an image step generated between adjoining correction regions is recognized as an image quality defect because it is visually recognized if the image step continues long although it is very minute, and to provide an image forming apparatus using the same.

At the time of correcting distortion of the image, the image correcting means corrects the image data 51 so that the continuing length of the image step generated between the adjoining correction regions due to insertion or thinning of correction pixels is shortened, by enlarging or reducing the magnification of the image data 51 to a preliminarily set magnification, and inserting or thinning the correction pixels to each correction region.

摘要： PROBLEM TO BE SOLVED: To reduce an influence of the precision of conveyance speed of a recording medium upon an image formation position of the recording medium. SOLUTION: The conveyance speed of a conveyed paper 110 is detected from rotation of a measuring roller 107, and the frequency of a clock signal generated by a clock signal generation part 113 is adjusted on the basis of the detection result. Detection processing for an image formed on the paper 110, of an image detection sensor 109 is controlled by the clock signal subjected to frequency adjustment. Thus, elongation/contraction of a picked-up image in a paper conveyance direction due to an influence of deviation from an ideal value or variations of the conveyance speed of the paper 110 is suppressed.

摘要： PROBLEM TO BE SOLVED: To suppress the lowering of productivity as compared with the constitution that a detecting pattern is erased at every formation thereof even when the positional shear of an image to be formed is detected.
SOLUTION: A magnetic head 12 is so constituted as to form the detecting pattern outside its image region for detecting the positional shear of an image to be formed by a magnetic latent image formed in an image region. A demagnetizing device 20 is set to maintain the detecting pattern without demagnetizing. So, neither erasion of the detecting pattern at every formation thereof nor formation of the detecting pattern at every detection thereof becomes necessary, resulting, in suppressing the lowering of productivity even when the positional shear of the image to be formed is detected.

摘要： PROBLEM TO BE SOLVED: To prevent image quality defects from being generated by suppressing a deflection in a pixel operating position when an image processing is applied for compensating a magnification gap for an image for which a screen treatment has already been applied. SOLUTION: This image forming device is equipped with an image compensating section 34 which inserts or eliminates pixels to an image based on a compensation value for correcting a registration gap of the image. The image compensating section 34 determines a specified interested region including a pixel operation position which is the position of pixels being inserted or eliminated, and calculates a color ratio which is a ratio between color pixels and colorless pixels in the view region. The image compensating section 34 determines the kinds of operating pixels which are objectives for the insertion or the elimination based on the color ratio, and performs the insertion or the elimination of the operating pixels to the interested region.

摘要： PROBLEM TO BE SOLVED: To obtain an image forming apparatus performing color shift correction by deforming an image through insertion or deletion of pixels in which image quality is enhanced by suppressing defects appearing in the image through insertion or deletion of pixels.
SOLUTION: The image forming apparatus comprises a control section for inserting/deleting pixels into/from image data when the image data inputted by an input means is written by a print means. The control section determines an pixel operating position for inserting/deleting pixels based on predetermined arrangement parameters, and employs a plurality of arrangement parameters in combination in order to determine the pixel operating position for the entire image data. The pixel operating position for the entire image data is determined by applying a matrix indicative of a pixel operating position in a region determined based on a plurality of arrangement parameters repeatedly.

摘要： PROBLEM TO BE SOLVED: To make it possible with a simple composition to enlarge the magnification-adjustable range in the main scanning direction while preventing the quality of image from degrading. SOLUTION: The adjustable range for image data (range wherein image degradation not to be generated) is established for the amount of correction of image data (ordinate-axis of graphic chart). A main-scan magnification correction section 70a enables an output-image magnification to be adjusted within the range in the direction of abscissa-axis from symbol-A to -F without making the quality of image degraded because of that a clock selector 82 can select either one of a standard clock, high-speed clock and low-speed clock and change it by controlling CPU68. A part of the range of image magnification in the main scanning direction wherein the adjustment is made in synchronizing with the low-speed clock or the high-speed clock overlaps to the range of image magnification in the main scanning direction wherein the adjustment is made in synchronizing with the standard clock.
