摘要： In an image forming apparatus, a black edge of a document image is emphasized, and the black edge is detected by deciding an edge from the lightness data and by deciding a black color from the chroma data. The data of cyan, magenta and yellow of a pixel at a black edge are replaced with minima of data of cyan, magenta and yellow of pixels in a prescribed region around the pixel. In order to prevent erroneous decision of a black edge, if a number of isolated pixels is larger than a threshold level, a decision as a pixel at a black edge is invalidated. Automatic exposure can be performed on a color document for correcting a background of the document obtained in a prescan. The background level of the document is determined only on pixels decided to be black. When color balance is adjusted on one of the data of cyan, magenta, yellow and black, the density is kept constant. A part of a color document is reproduced in a sheet of paper with use of different levels of an image forming condition such as edge emphasis. That is, image data on the same part of the color data are supplied repeatedly, while image forming condition on the color data are changed successively. Then, the color data of the part is formed repeatedly in a sheet of paper at different levels of the image forming condition.

摘要： In an image processor, an image of document is read by an image sensor. A reduction ratio of the image is set. Then, interpolation is performed on the image data between a pixel under interest and a pixel adjacent to the pixel under interest according to the reduction ratio. After the interpolation, pixel data in the image data are thinned out to an image data having a size determined by the reduction ratio, and an image is formed on a sheet of paper based on the thined-out data. Because the interpolation is performed before the thinning-out of the image data, defects in a reduced image such as vanishment of a narrow line are reduced, and image quality is improved.
