摘要： Color image information is converted to black-and-white image information. Based on the converted black-and-white image information, a black-and-white printout is obtained. At least either brightness or saturation is independently controlled for each desired hue, based on a color image signal carrying the color image information. The controlled color image signal is converted to a black-and-white image signal carrying the black-and-white image information, and the black-and-white printout is obtained based on the converted black-and-white image signal.

摘要： An image forming apparatus includes an original read-out station which is provided on an image forming apparatus body and on which an original is placed and read out in a predetermined read-out position, a digitizer for designating an area of the original, and an automatic document feeder for feeding an original to the read-out position. The automatic document feeder and the digitizer are mounted on the image forming apparatus body for rotation about respective axes between their respective operative positions where they are opposed to the original read-out station and their respective retracted positions where they are away from the original read-out station to open the original read-out station. The automatic document feeder is provided with a digitizer receiving portion on the side which is opposed to the original read-out station when the automatic document feeder is in the operative position so that the digitizer is received in the digitizer receiving portion of the automatic document feeder when the automatic document feeder and the digitizer are both in their operative positions.
