Abstract
An image processing system includes an image reader unit which reads an image so as to generate it as 4-bit data, and a communication unit for converting the 4-bit data into 6-bit data. The communication unit forms the 6-bit data in such a manner that an upper 2-bit component of the 4-bit data is added to the 4-bit data as a lower 2-bit component of the 6-bit data. The resultant 6-bit data is supplied to a binary printer and is subjected to halftone processing and printing. Image signals having different bit numbers can be processed and excellent image reproduction can be achieved with a simple system.
