Title: Picture communication system and its controlling method
Inventor: IZUMI MICHIHIRO
IPC: H04N5/225
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To execute the output selecting operation of picture data from a picture input device by simple processing by transmitting a different control signal in accordance with the visible output of the picture data or the transmission of the picture data through a communication line. SOLUTION: In the case of color-printing picture data obtained by a digital camera 303, a CPU in the camera 303 detects the depression of a printing button on an operation part and transmits a 'printing request' message to a facsimile(FAX) equipment 302. At the time of detecting the depression of 'line transmission' on the operation part in the case of transmitting the picture data from the camera 303 to an outer opposite party connected through an ISDN, the CPU in the camera 303 transmits a 'line transmission request' message to the FAX equipment 302. Thus the printing-out picture data and its FAX transmission to a communication line can be executed only by changing the operation of the camera 303 without executing the transfer of data to a personal computer 304 or re-connecting the data.
