发明名称 Image-information format control device.
摘要 The present invention makes it possible to execute communication between an image-information storage and a terminal even in case they have different image formats. An image data delivery request transmitted from any of terminals (11a - 11c) and received by a receiving portion (13) includes an information indicating that the terminal has a source format CIF or QCIF. This information is transferred to a communication control portion (14) which informs an source format control portion (17) 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 (19) are transmitted through a transmitter portion to the terminal. When the terminal 11d has the QCIF source format, a part of the image data transferred from the image-information storage device (19) is extracted and converted into data of QCIF format by the source format control portion (17). The converted data of QCIF source format are then transmitted through a transmitting portion (15) to the terminal (11d). <IMAGE>
