An image transmission apparatus is provided with a FAX modem, an encoding/decoding section, a digitizer-integrated LCD, encoded image data memory, original image data memory, and additional image data memory. Original image data received by the FAX modem are temporarily stored in the encoded image data memory, and the original image data are decoded by the encoding/decoding section. The thus-decoded original image is stored in the original image data memory. An image of the thus-stored original image data is displayed on the digitizer-integrated LCD. An operator draws an additional image on the digitizer-integrated LCD. Data of the thus-drawn additional image are stored in the additional image data memory. The thus-stored additional image data are encoded by the encoding/decoding section, and the thus-encoded additional image data are temporarily stored in the encoded image data memory. Then, the encoded additional image data are sent by the FAX modem.

The thus-decoded original image is stored in the original image data memory. An image of the thus-stored original image data is displayed on the digitizer-integrated LCD. An operator draws an additional image on the digitizer-integrated LCD. Data representing the thus-drawn additional image are stored in the additional image data memory. The thus-stored additional image data are encoded by the encoding/decoding section, and the thus-encoded additional image data are temporarily stored in the encoded image data memory. Then, the encoded additional image data are sent by the FAX modem.

A handwriting stroke information encoder capable of reducing costs resulting from communication and storage of encoded data by reducing the amount of the encoded data. The handwriting stroke information encoder is provided with a processor which calculates forecast coordinates from sampled coordinates to be encoded and coordinates sampled before the sampling of the sampled coordinates, and an encoder which encodes the differences between the forecast coordinates and sampled coordinates of an actual input. The coordinates are forecast as; e.g., coordinates that are in line with the extension of vector, which are connecting together the previously-sampled coordinates and coordinates sampled prior to the previously-sampled coordinates, and are spaced the magnitude of the vector away from the previously-sampled coordinates.
