Title: Picture communication terminal
Inventor: KUWABARA TOMOYUKI
IPC: G10L19/00
Filed: 2000-03-23
Abstract: PROBLEM TO BE SOLVED: To solve the problem that an ilIuminator installed in a video telephone system with light which is a conventional picture communication terminal cannot be controlled from an opposite video telephone system though the illuminance of the illuminator is controlled on the basis of a measured result of a photometric circuit in order to allow an image to be outputted to the opposite system to facilitate viewing. SOLUTION: A sound interface part 9a converts a signal '1-9', indicating the degree of illuminance of the illuminator 13 of its own system which is sent from an operation part 15 of the opposite system, into a PB signal and outputs the PB signal to a sound encoding/decoding device 8. In its own system, a PB signal detection circuit 18 inversely converts the PB signal sent from the opposite system and outputs the inversely converted signal to a system control circuit part 14a. Thereby the circuit 14a of its own system outputs the degree of illuminance corresponding to the signal '1-9' outputted from the opposite system. Consequently the illuminator 13 controls the illuminance matched with the inputted illuminance degree. Namely the illuminace of the illuminator 13 of its own system can be controlled from the opposite system.
