    Abstract: An image forming apparatus of this invention includes an image forming position correction unit which corrects an inclination or curve of an image in the main scanning direction by converting coordinates designating pixel positions of a bitmap image in the sub-scanning direction. It is discriminated whether image formation is normal image formation or formation of the toner image for detection by an image forming condition correction unit. Based on the discrimination result, the image forming apparatus is controlled so as to correct the image forming position by using the image forming position correction unit in a case in which the image formation is discriminated as the normal image formation, but so as not to correct the image forming position by using the image forming position correction unit in a case in which the image formation is discriminated as formation of the toner image for detection.

  • Patent number: 8040555
    Abstract: Methods, algorithms, software, apparatuses and systems for processing image data for imaging devices having irregular scan paths (e.g., scan paths that deviate from a conventional horizontal and/or straight line). The irregular scan paths generally correspond to actual locations of a line of output from an image output device (e.g., a printer). The method generally includes steps of selecting one or more of the input pixels, correlating a location of the selected pixel with a location on an irregular scan path, and producing an adjusted pixel based on a value of the selected pixel, the location on the irregular scan path, and/or values of one or more pixels near the selected pixel. The present invention advantageously allows for processing an input image for an output device with an irregular scan path using only enough working memory for a relatively small number of pixel rows even if the irregular scan path traverses a relatively large number of rows in the output image.

  • Patent number: 7991197
    Abstract: The class of a sheet is efficiently estimated and a pattern identification process which is robust to a variation in the medium can be performed by dividing an image pattern of the sheet into a plurality of areas (pixels or sets of pixels), weighting and selecting the areas, attaining the identification results for the respective areas and determining the identification result of the whole portion based on a logical combination of the identification results. Particularly, since the area weighting and selecting process is performed based on a difference between the classes and a variation in the class, the calculation amount can be reduced and the identification performance which is higher than that of a method which uniformly processes the whole portion of the pattern can be attained.

  • Patent number: 7990572
    Abstract: An optical scanning device 65 is adapted to bring a deflector mirror plane 651 into independent pivotal motions about a first axis and a second axis perpendicular to each other. A mirror driver section including a first axis driver and a second axis driver is so controlled as to bring the deflector mirror plane 651 into pivotal motion about the first axis thereby deflecting a light beam L for scanning along a main scan direction. On the other hand, the deflector mirror plane 651 is pivotally moved about the second axis thereby to adjust the scanned beam L for its position on a photosensitive member 2 with respect to a subscan direction. Thus, even if the scanned beam is deviated from a reference scan position with respect to the subscan direction due to component tolerances or assembly errors, such a deviation can be corrected.

  • Publication number: 20110149305
    Abstract: In image processing, it is possible to suppress density fluctuation and keep graininess low as well as obtain a good balance of the processing load. More specifically, when dividing multi-valued data and generating two-pass multi-pass printing data, divided multi-valued data that is common to the two passes is generated in addition to the divided multi-valued data for each of the two passes. Moreover, quantized data of that common multi-valued data is reflected on the quantized data for each pass. Furthermore, when generating quantized data, a process of generating common data by the aforementioned data division, or a process of performing quantization first without dividing the multi-valued data and then dividing the quantized 2-pass data is selectively performed according to the printing position on printing medium.

  • Patent number: 7957043
    Abstract: In an image recording apparatus, shift times for shifting switching timings of light modulator elements are obtained so that rise times (U1) after input of output start signals to driving elements connected to respective light modulator elements of a spatial light modulator and fall times (D1) after input of output stop signals become a constant target rise time (U2) and a constant target fall time (D2). This makes it possible to suppress unevenness of the rise times and the fall times after correction of light amounts even if light modulator elements where the rise times and the fall times change by correction of light amounts are used and consequently, an image can be appropriately recorded without a complicate apparatus.

    Abstract: A determination unit determines density correction characteristics to be applied to correct density characteristics based on a reading result obtained by a reading unit. A measuring unit measures a density value of the image pattern formed on the image carrier by the image forming unit at the first image forming speed by applying the density correction characteristics. A reference density value storage unit stores, as a reference density value, the density value of the image pattern measured by the measuring unit. A creation unit creates modification data to modify the density correction characteristics for a second image forming speed from a difference between a density value of an image pattern formed on the image carrier by the image forming unit at the second image forming speed by applying the density correction characteristics, and the reference density value stored in the reference density value storage unit.
