PURPOSE: To release a host computer from spending time for transferring the data of a picture object by providing a picture deleting means, picture activity ratio monitoring means which monitors the activity ratio of a stored picture object, and a picture outputting means which outputs a picture object from a file to the displaying section of a terminal device.

CONSTITUTION: This transferring picture object management device 1 incorporates a picture managing means 11, picture number monitoring means 12, picture deleting means 13, picture storing means 14, picture activity ratio monitoring means 15, and picture outputting means 16 and is connected to a transferring picture object storing device 2 and terminal device 3. Since a picture object can be automatically stored in an external storage device 4 on the terminal device 3 side by utilizing this management device 1, any frequently used picture object can be displayed on the displaying section of the terminal device 3 by inputting a reading command and picture object name only. Therefore, a host computer can be released from the execution of complicated processes for transferring picture objects.
