Abstract: A transmission control system for a facsimile transceiver allows two facsimile transceivers having different buffer memory sizes and decoding rates different from encoding rates to intercommunicate within a short period of time. Start and stop of encoding and insertion of fill bits are controlled on the basis of an amount of data stored in a buffer memory of a transmitting transceiver, which temporarily stores encoded data, and various conditions associated with a receiving transceiver, so that the number of bits encoded data per line is averaged over a plurality of lines. This decreases the transmission time and, thereby, increases the transmission rate without resorting to an increase in the processing rate of a reader or that of a recorder or an increase in modem rate.

Abstract: An information processing apparatus for transmitting image data input by sequentially reading documents, with limiting an allowable frame size, includes: a transmission controller, wherein, in a case where the document has an irregular size, the transmission controller transmits the image data to a transmission destination in a preset frame of a first frame size until a rear edge of the document is detected, and if a portion, which is not transmitted, of the image data exists when the rear edge of the document is detected, transmits the portion to the transmission destination in a frame of a second frame size smaller than the first frame size so that the transmitting of the portion is finished before a start of transmission of image data corresponding to a next document.

Abstract: An original is read by an original reading unit configured to read image data, at least one of the original reading unit and the original is driven by a driving motor in a sub-scan direction, and, when an amount of the image data stored by the image data storing unit becomes equal to or more than a predetermined amount, the rotational speed of the driving motor is reduced according to driving control data provided for each of current rotation angles of the driving motor for finally stopping the driving motor at a predetermined rotation angle, and a speed in a sub-scan direction at which the original reading unit reads the original is reduced. Then, main scan line data are thinned out from the image data according to thin-out data provided for each driving control data, and image data of the original are restored.
