Abstract: An image processing device includes a mode instruction information obtaining section, a color determination threshold storage section, a mode determination section, and an automatic color determination threshold adjustment section. The mode determination section, using a color determination threshold, determines a mode to be a color mode when the image data belongs to a color mode range, and determines the mode to be a monochrome mode when the image data belongs to a monochrome mode range. The automatic color determination threshold adjustment section adjusts the color determination threshold so as to widen a mode range corresponding to the mode determined by the mode determination section, when the mode indicated by the instruction information obtained by the mode instruction information obtaining section is different from the mode determined by the mode determination section.

Abstract: The character edge area determining unit (21) determines a character edge area in input image data.The output image processing unit (12) performs an image process for a target pixel in the determined character edge area in order to adjust a toner consumption amount in accordance with the number of continuous edge pixels (i.e. continuous pixels that belong to the character edge area) included in a reference window of which a center is set on the target pixel and an average value of pixel values of the continuous edge pixels.

Abstract: An image processing apparatus includes a single-color image reading circuit and a fluorescent color area extracting circuit. The single-color image reading circuit reads an image on a document to create single-color image data. The fluorescent color area extracting circuit extracts a fluorescent color area included in the single-color image data based on pixel values of respective pixels constituting the single-color image data created by the single-color image reading circuit.

Abstract: An image forming apparatus includes an image reading unit, an image forming unit, and a color calibration processing unit. The image forming unit forms an image on an image forming medium using image forming color materials of a plurality of colors including CMY. The color calibration processing unit sets, in consideration of the integrated value of the product of the spectral transmittance and the spectral reflectance in the visible region of the reference document measured by the external colorimeter and the color material image formed using the image forming color materials on the image forming medium, a difference feature amount for bringing the color of the color material image closer to the color of the reference document by using the integrated value of the product of the spectral transmittance and the spectral reflectance in the visible region calculated from the XYZ values measured by the external colorimeter.

Abstract: The edge pixel determining unit (21) determines edge pixels in an input image, and the property determining unit (23) determines an edge pixel of a ruled-line edge among the determined edge pixels. The output image processing unit (12) performs predetermined image processing for the edge pixels so as to make a toner consumption amount of the edge pixel of the ruled-line edge smaller than a toner consumption amount of an edge pixel other than the edge pixel of the ruled-line edge.
