Abstract: An image processing apparatus according to embodiments obtains a variance value of signal values of pixels included in a predetermined region of the read image read from an original, and compares the obtained variance value with a threshold value for determining whether the read image has a halftone dot region. Furthermore, the present image processing apparatus, upon determining that the read image includes a halftone dot region in accordance with the result of this comparison, executes a first removal process for removing the reflection of an image of one surface of an original when reading the other surface, and executes a second removal process otherwise.

Abstract: An apparatus that enables an operator to easily perform an image diagnosis by ascertaining an analysis image that does not include an unnecessary image and that reduces a user's superfluous indication. A forming unit forms an image on a sheet. An image reading unit reads image data from an original. An output processing unit outputs a second analysis image that is obtained by adding a predetermined image pattern to a first analysis image for an image diagnosis to a sheet with the forming unit. A read processing unit reads the sheet on which the second analysis image is output with the image reading unit and generates first image data. An analysis unit analyzes the first image data. An erasing unit generates second image data that is displayed for the image diagnosis by erasing the predetermined image pattern from the first image data.

Abstract: An image processing apparatus includes a first determination unit to determine an attribute of an area included in an input image obtained by reading a document, a second determination unit to determine saturation of an area determined to be a halftone dot area by the first determination unit, and a background removal unit to remove a background included in the input image. The background removal unit converts for an area determined to be a halftone dot area by the first determination unit and whose value indicating saturation is determined to be less than a predetermined value by the second determination unit, a color of a pixel of pixels making up the area, which has a pixel value greater than a first level, into white.

Abstract: An image processing apparatus includes an input unit that inputs image data. A receiving unit receives an instruction on a mode for saving color material to be consumed by printing the image data. A processing unit performs processing for increasing a width of a line constituting a white character included in image data in a case when the receiving unit receives the instruction on the mode for saving a color material to be consumed by printing.

Abstract: An image processing apparatus extracts, from color image data, an object having a first density and an object having a second density being higher than the first density, and determines whether or not sizes of the objects each having the first density and the second density are greater than a predetermined size. When converting the color image data into monochromatic image data, an object having the first density and a size less than or equal to the predetermined size is converted to have a higher density than an object having the first density and a size greater than the predetermined size, and an object having the second density and a size less than or equal to the predetermined size is converted to have the same density as an object having the second density and a size greater than the predetermined size.

Abstract: Under-color removal of show-through background from a scanned original, so as to retain chromatic highlights of the scanned image of the original. An under-color level defines a value at which signals having a higher luminance than a luminance of the under-color level are converted into white. Before under-color removal, and based on the scanned image of the original, an achromatic color is converted into a color closer to white than the under-color level for an achromatic color closer whose luminance falls in a specified range lower than the luminance of the under-color level; and a chromatic color is converted into a chromatic color having a lower luminance than the luminance of the under-color level for a chromatic color in the specified range. Under-color removal of the converted achromatic and chromatic colors is thereafter applied using the under-color level, by which signal values having a higher luminance than a luminance of the under-color level are converted into white.

Abstract: An image processing apparatus according to the present invention effectively suppresses an amount of consumption of a color material even with respect to an image including a white character by not performing width-reducing processing with respect to a white character or line but performing width-reducing processing with respect to a character or line that is not a white character. Furthermore, the amount of consumption of a color material is further suppressed by performing width-increasing processing on a white character or line.
