US 4,905,097 A · Image processing system capable of processing both binary and multivalue image data and having converters for converting each type of image data into the other type of image data

Abstract

An image processing system receives image data on a pixel unit basis and converts it into a digital signal and processing it. This system includes: a binary image processor to image process one pixel of image data as a binary digital signal (binary image data); a multivalue image processor to image process one pixel of the image data as a multivalue digital signal (multivalue image data); a binary/multivalue converter to convert the binary image data into the multivalue image data; and a multivalue/binary converter to convert the multivalue image data into the binary image data. The binary image processor and multivalue image processor can transmit and receive data therebetween and can image process any of the binary image data and multivalue image data. The binary digital data is directly transferred to the multivalue image processor. The multivalue digital data is converted into the binary data by the multivalue/binary converter and thereafter, this binary data is transferred to the binary image processor. With this system, the binary and multivalue image data can be integratedly image processed.
