An image processing is configured to convert a color of a first object into gray having first brightness and a color of a second object into gray having second brightness lower than the first brightness by a fixed value in response to receiving color data including the first object and the second object, and output gray data based on the first brightness of gray into which the color of the first object is converted and the second brightness of gray into which the color of the second object is converted.

Apparatus, method, and storage medium for converting a color image to a monochrome image

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.

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.

An image processing apparatus has a first color conversion unit that converts a signal value at an achromatic grid point in a first color space among achromatic grid points in a color space, the signal value being closer to white than a first predetermined signal value, into a signal value that is even closer to white, and a second color conversion unit that converts a signal value at a grid point among grid points in the color space, the signal value being closer to white than a second predetermined signal value, into white are provided. The image processing apparatus converts a signal value of an input image using the first color conversion unit, and thereafter converting the signal value using the second color conversion unit.

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.

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.

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.

An object of the present invention is to appropriately control a display relating to charging accompanying printing processing in accordance with the situation on the side of a printing apparatus in an information processing apparatus that is connected to the printing apparatus. The present invention is an information processing apparatus including an acquisition unit configured to acquire information on a printing apparatus that is specified as an output destination by a user and a determination unit configured to determine whether or not to present charging information relating to printing based on the acquired information on a printing apparatus.

In a case where one of setting information relating to image adjustment and setting information relating to stepwise charging is changed, an influence that is exerted on the other is immediately checked. A corresponding information processing apparatus includes a first reception unit configured to receive an image adjustment setting value that specifies a degree of adjustment processing for image data, and a second reception unit configured to receive a setting value in stepwise charging in which a charging amount increases stepwise as a toner consumption amount increases, and in the information processing apparatus, in the case where one of the received image adjustment setting value and the received setting value in stepwise charging is changed, the other is changed in accordance with the changed value.
