Abstract
Communication between an image-information storage device and a terminal is made possible even in a case where they have images of different image formats. An image data delivery request, transmitted from any of a plurality of terminals and received by a receiving portion, includes information indicating that the terminal has a source format of CIF or QCIF. This information is transferred to a communication control portion which informs the source format control portion of the source format (CIF or QCIF of) the terminal. When the terminal has the CIF source format, the required data transmitted from an image-information storage device are transmitted through a transmitter portion to the terminal. When the terminal has the QCIF source format, a part of the image data transferred from the image-information storage device is extracted and converted into data of QCIF format by the source format control portion. The converted data of QCIF source format are then transmitted through a transmitting portion to the terminal.
