Abstract: When enlargement processing is performed, binary image data inputted from a data line 100 is subjected to contour smoothing by a contour smoothing and enlarging circuit 2 and the data is enlarged by a factor of n (where n is an integer) in the main scanning direction and m (where m is an integer) in the subordinate scanning direction. When reduction processing is performed, the binary image data is outputted as is from a selector 6 to a multivalue-converting circuit 3 via a signal line 200. In the multivalue-converting circuit 3, the binary image is stored temporarily in a memory, the image data of any area is extracted, image data of multivalued density is calculated based upon a window outputted from a weighting table with reference to an area comprising a pixel of interest and its peripheral pixels, and the multivalued data is outputted to a variable-power circuit 4 via a signal line 300. In the variable-power circuit 4, the multivalued-density image data is zoomed down to any size by thinning-out processing based on an image clock and line synchronizing signal, and the resulting data is outputted to a binarizing circuit 5 via a signal line 400. The binarizing circuit 5 converts the image data of multivalued density into binary data and outputs this data on a data line 500.

Abstract: Image data communication equivalent to facsimile communication using a public network is realized on e-mail communication. When a communication apparatus for transmitting/receiving e-mail data by connecting to the Internet is to communicate e-mail data having facsimile-format image data attached, communication concerning functional information is performed in addition to the communication of the e-mail data. The functional information can be exchanged by an optimum method matching the form of connection to the Internet. This allows maximum utilization of the capability of each apparatus function in facsimile image communication using e-mail.

Abstract: Disclosed are an image processing method and apparatus for applying spatial filtering processing to n-bit multilevel image data, converting the processing image data to two-level or multilevel image data and converting the resulting image data to data capable of being expressed using high-resolution dots. The filtered image data is subjected to a luminance-to-density conversion and is further converted to two or four levels by a four-level/two-level conversion circuit which makes common use of circuitry for executing both two-level error diffusion processing and four-level error diffusion processing. The four-level/two-level conversion circuit clamps the error produced in four-level conversion processing to the number of significant bits of the error produced at execution of the two-level conversion processing. As a result, a common circuit can be used for both the two-level conversion processing and the four-level conversion processing.

Abstract: A buffer memory control device has a plurality of generating units which generate image data of differing formats one line at a time. A storage unit temporarily stores at least one line of image data generated by one of the generating units. A plurality of processing units perform differing image processing of at least one line of image data read from the storage unit. A control unit controls the number of lines of image data to be temporarily stored in the storage unit and the amount of data per line, based on the generating unit which generates the image data stored in the storage unit and the processing unit which performs image processing of the image data read from the storage unit.
