Abstract: 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.

Abstract translation: 在图像形成装置中，强调文件图像的黑色边缘，并且通过根据亮度数据确定边缘并通过从色度数据确定黑色来检测黑色边缘。 在黑色边缘处的像素的青色，品红色和黄色的数据被替换为在像素周围的规定区域中的青色，品红色和黄色像素的数据的最小值。 为了防止黑色边缘的错误判定，如果多个孤立像素大于阈值电平，则作为黑色边缘处的像素的判定无效。 可以在彩色文档上执行自动曝光，以校正在预扫描中获得的文档的背景。 仅在决定为黑色的像素上确定文档的背景级别。 当在青色，品红色，黄色和黑色的数据之一上调整色彩平衡时，密度保持不变。 使用不同程度的图像形成条件（例如边缘强调），以一张纸再现彩色文档的一部分。 也就是说，重复地提供彩色数据的相同部分上的图像数据，同时连续地改变颜色数据上的图像形成条件。 然后，在图像形成条件的不同水平的纸张中重复地形成该部分的颜色数据。
