  • Patent number: 8427707
    Abstract: A reference area is extracted from image data, and from the pixels included in the reference area, extracted are a plurality of small sections in which pixels are arranged so as to be symmetrical with respect to the center pixel of the reference area in the horizontal and vertical directions, and point-symmetrical with respect to the center pixel, while overlap of pixels is allowed between each of the small sections. Determination is made as to whether or not image data included in the reference area matches a predetermined pattern. A characteristic of the image data in the reference area is determined based on a number of characteristics of the plurality of small sections. Based on the results of the determination, it is judged whether or not to perform smoothing on the center pixel of the reference area. Then, the smoothing is performed on the judged center pixel.

The mask data can be used to complete quickly rendering of a page image once the rendering starts. Another aspect enables color fills of objects to be performed efficiently. A raster operations engine may determine whether all the points (pixels) of the object would have the same value if the raster operation is performed. If all pixels would have the same value, the value for only one pixel is computed and used for multiple pixels of the object. According to another aspect, when a pattern is to be tiled on an entire image portion, the pattern data is stored in a memory and provided as an input to rendering operation multiple times.

    Abstract: In order to prevent illegal copying more effectively in an image forming apparatus, when a specified ground pattern for preventing copying is detected in input image data, the detected ground pattern is emphasized in the image data. Alternatively, information for detecting the specified ground pattern is stored in a storage device, in order to detect the ground pattern with the stored information. When the ground pattern is not detected, a ground region in the image data is analyzed further to determine whether a different ground pattern exits or not. When a ground pattern is detected, information for detecting the ground pattern is stored in the storing device.

    Abstract: An image file representing at least a portion of a printed document is processed to highlight the differences between foreground material (e.g., text or other characters) from background. The method includes selecting a neighborhood of pixels, determining a weighted average of an attribute values (e.g., luminance) for each pixel, and modifying each pixel's value based on the weighted average. Graylevel scaling, error diffusion, and a bit level conversion are also performed each pixel ends up with either a first attribute value level (e.g., luminance of 0) or a second attribute value level (e.g., luminance of 255).

  • Patent number: 8223392
    Abstract: According to a fine line detection processing, when for a subject pixel to be subjected to the fine line detection processing, a 3×3 matrix area centered on this subject pixel is set as a subject area. Point values “0” to “8” are assigned to the matrix elements constituting this 3×3 matrix subject area. Then, three pixels with the first, second, and third lowest brightness values are extracted from the subject area. When the total point value of the three extracted pixels is equal to “12”, the extracted pixels are determined as being in a connected state. Then, an intermediate value is calculated from the minimum and maximum values of brightness (Y) of pixels in the subject area. When the number of pixels with a brightness (Y) value smaller than the intermediate value is less than 4, the subject pixel is determined as being a fine-line pixel. A fine-line code is added to the subject pixel that is determined as being a fine-line pixel.

  • Patent number: 8213053
    Abstract: A type detecting part detects types of drawing objects included in a printing job. A rate detecting part detects a rate of each type of drawing object. A storing part stores the rate of each type of drawing object as a count value of a statistics counter which counts predetermined units of drawing objects for each type of drawing object. A comparing part compares a previously set printing quality with a recommended printing quality which is derived from count values of statistics counters. A changing part changes the previously set printing quality to the recommended printing quality when the previously set printing quality is different from the recommended printing quality.

  • Patent number: 8208171
    Abstract: The present invention aims to prevent a problem that an image on a document sheet is erased due to misdetection of a line-shaped noise. A copy machine 1 compares RGB values of a target pixel with averaged RGB values (Step S103). If only one of the RGB values has a difference that is greater than a prescribed value Ref2 (Step S103: YES), the copy machine 1 extracts the target pixel as a line-shaped noise pixel, and moves to a line-shaped noise correction (Step S108) while holding the address of the target pixel in a line-shaped noise address storing area 49b. If two of the RGB values have differences (Step S103: NO, Step S104: YES) and a difference between these two of the RGB values is no greater than a prescribed value Ref3 (Step S105: YES), the copy machine 1 extracts the target pixel as a line-shaped noise pixel, and moves to the line-shaped noise correction (Step S108) while holding the address of the target pixel in the line-shaped noise address storing area 49b.

    Abstract: A color difference ?E between a target color value expressed by color measurement data MD obtained by measuring colors of a target TG under plural light sources and an estimation color value obtained when a printer performs printing on the basis of an ink amount set ? is calculated for each of the light sources. When the color difference can be calculated for each of the light sources, an evaluation value E (?) obtained by linear combination of the color differences is calculated. In addition, the ink amount set ? is calculated as an optimum solution for minimizing the evaluation value E (?).

  • Patent number: 8159722
    Abstract: 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.
