Method and apparatus for registering modification pattern of transmission image and method and apparatus for reproducing the same

An apparatus for registering a modification pattern of a transmission image, comprising

• reading means for reading out contents associated with a modification pattern modifying the transmission image to be displayed on a second image display unit of a second communication device when a first communication device including a first image display unit of a first person in communication is communicating with the second communication device including the second image display unit of a second person in communication through a relay center;
• copying means for copying said modification pattern from the contents read out by said reading means;
• and
• storing means for registering and storing said modification pattern copied by said copying means in such a manner that said first person in communication or said first communication device is capable of using said modification pattern.

A method of reproducing a modification pattern of a transmission image, comprising the steps of:

• reading out contents associated with said modification pattern modifying the transmission image to be displayed on a second image display unit of a second communication device when a first communication device including a first image display unit of a first person in communication is communicating with the second communication device including the second image display unit of a second person in communication through a relay center;
• copying said modification pattern from the thus read out contents;
• registering the thus copied modification pattern in such a manner that said first person in communication or said first communication device is capable of using said modification pattern;
• reading out by the first communication device said modification pattern registered by means of said registering step;
• and
• reproducing and displaying said readout modification pattern on the first image display unit of the first communication device, the second image display unit of the second communication device or an image display device of the relay center.

An apparatus of reproducing a modification pattern of a transmission image, comprising

• first reading means for reading out contents associated with a modification pattern modifying the transmission image to be displayed on a second image display unit of a second communication device when a first communication device including a first image display unit of a first person in communication is communicating with the second communication device including the second image display unit of a second person in communication through a relay center;
• copying means for copying said modification pattern from the contents read out by said reading means;
• storing means for registering and storing said modification pattern copied by said copying means in such a manner that said first person in communication or said first communication device is capable of using said modification pattern;
• second reading means for reading out said modification pattern registered by said storing means and provided in the first communication device;
• and
• reproducing means for reproducing and displaying said read-out modification pattern on the first image display unit of the first communication device, the second image display unit of the second communication device or an image display device of the relay center.
