发明名称 Image processing method and apparatus
摘要 <p>An image processing apparatus adding information to read image signals and arranging a mark indicative of a position where the information is added so that the additional information can be easily extracted. An image processor processes full-color image signals from a line sensor and a binarization circuit binarizes the signals using a pseudo half-tone processing. A density judgment circuit judges the density of the image signals and controls a modulator which adds additional information. The modulator refers to the contents of a ROM and changes dot positions in the binarized image signals based on the referred information and adds the additional information to the image signals. A FIFO compensates image signals delayed by the density judgment circuit. &lt;IMAGE&gt;</p>
