The present invention is a color correction system including an imaging apparatus which inputs or outputs an image signal from a signal processor into or from an image device such as an input device such as a scanner or a camera or an output device such as a display device or a print device and which is constituted so as to correct colors by inputting or outputting image signals via a color converter, the conversion characteristic of which can be controlled according to a variation in the setting status or use environment of the imaging apparatus and faithful color reproduction can be realized between a plurality of imaging apparatuses having different characteristics.

Color correction system of imaging apparatus

A video telephone system which includes a master video telephone terminal (secretary terminal) connected to a communication network and slave video telephone terminals (executive terminals) connected to the master video telephone terminal in which the master video telephone terminal can transfer a call to the slave video telephone terminals. When a call comes into the secretary terminal from a remote terminal on the communication network, a line control section of the secretary terminal sets up a line. Video data and speech data received on the line are decoded by a video signal coding-decoding section and an aural signal coding-decoding section and the decoded signals are output through a display and a speech output device. Sound and images picked up by a microphone and a camera respectively are coded for transmission. Then, if a predetermined instruction of call transfer to an executive terminal is entered on an electronic tablet of the secretary terminal, a communication branch control section of the secretary terminal calls the executive terminal, sets up a line between the secretary and executive terminals on a local transmission network, and connects the line between the secretary terminal and the remote terminal.
