Abstract

PURPOSE:To improve the picture displayed to the opposite party at holding and to discriminate a holding indication from a busy state indication by switching a changeover section at holding to send a holding picture signal of a holding picture signal storage section to the opposite party equipment. CONSTITUTION:When a hold key in a telephone section 5 is operated during talking, a hold command (b) is sent to a communication processing section 4. Upon the receipt of the command (b) from the telephone section 5, the processing section 4 outputs a switching signal (c) to a changeover section 3 and a holding coding data storage section 7. As a result, a contact of the changeover section 3 is thrown to the position (b) and a holding coding data storage section is started. Thus, in this case, the output of picture data picked up by a camera 1 and coded by a picture data coding section 2 is stopped and the holding picture data stored in the storage section 7 are outputted to the line 6 via the contact (b) of the changeover section 3, a communication processing section 4 and the telephone section 5 in place of the coded picture data and sent to the opposite party equipment.

As described above, in the videophone device of the present invention, when the call is put on hold, instead of the image signal picked up by the camera 1,
By transmitting the hold image signal stored in advance in the hold coded data storage unit 7 to the partner device, a display service that can be clearly identified from a call is provided and the display service is improved. It was done. In this embodiment, the holding coded data storage unit 7 for storing the holding image signal is constituted by the ROM, but it may be constituted by the RAM capable of rewriting data. In this case, the user can freely create the holding image data and store and hold it in the RAM. Further, in the present embodiment, the data in the coded data storage section 7 for holding is output to the line 6 during holding. However, when this apparatus is used as an answering machine, a holding code composed of RAM or the like is used. It is also possible to realize the answering machine function by storing the image data corresponding to the message for the answering machine in the encoded data storage unit 7 and transmitting the image data to the partner device during the absence.
