Facsimile apparatus comprising converting means for converting binary image data into multi-value image data

摘要

In a facsimile apparatus, image data receiver receives compressed image data transmitted from a transmission apparatus apart from the facsimile apparatus. A first expanding section expands the received image data using a first expanding method, and a second expanding section expands the received image data using a different second expanding method. A data converter converts white and black binary image data into multi-value image data in multi-gradation stages representation, and a judging section judges whether the received image data are binary image data or multi-value image data. Further, a controller controls the first expanding section and a printer to expand the compressed image data judged as multi-value image data and thereafter print in multi-gradation stages an image corresponding to the expanded image data, and also controls the second expanding section, the data converter and the printer to expand the compressed image data judged as binary image data, convert the expanded image data into multi-value image data, and thereafter print in multi-gradation stages an image corresponding to the converted multi-value image data.
