Abstract: An image data generating apparatus includes an extracting unit and a generating unit. The extracting unit extracts one or more pixels corresponding to a metallic-color region expressed by a metallic color, by using lightness and saturation of a read image and lightness and saturation of a captured image, the read image being obtained by reading a document having the metallic-color region, the captured image being obtained by capturing an image of the document. The generating unit generates image data in which the one or more pixels corresponding to the metallic-color region and extracted by the extracting unit are colored in the metallic color.

Abstract: An image forming apparatus includes: an image forming unit that forms an image on a recording material by ejecting ink; and an image processing unit that, in a case where information of a bar code image is included in image information for forming an image by the image forming unit, carries out a process of making a drop size of the ink used for pixels constituting an edge portion in the bar code image smaller than a drop size of the ink used for pixels constituting a portion other than the edge portion.

Abstract: An image forming apparatus includes an image forming section and an image processing section. The image forming section forms an image on a recording medium. When image information for forming the image with the image forming section includes information of a barcode image and one of a resolution of the image forming section and a resolution of the image information is not an integer multiple of the other, the image processing section regards a resolution of a part of the image information used for the barcode image as a different resolution so that one of the resolution of the part of the image information used for the barcode image and the resolution of the image forming section is an integer multiple of the other to perform rasterization.

Abstract: An image processing apparatus includes an edge-portion detector, an edge-width detector, and a tone correction unit. The edge-portion detector detects a pixel of an edge portion by determining whether or not each of pixels constituting image data which has been input is a pixel which is included in the edge portion. The edge-width detector detects, for the pixel of the edge portion detected by the edge-portion detector, an edge width which is a width of the edge portion. When the edge width detected by the edge-width detector is smaller than a value which is set in advance, the tone correction unit performs tone correction differently in accordance with the detected edge width.
