Patent Images
1. A system for video call, comprising:
- one or more terminals configured to transmit images obtained by capturing video call users; and
a video call control server configured to generate a combined image by combining the images transmitted by the one or more terminals, and to transmit the combined image to the terminals,wherein one or more of the respective images are rotated based on orientation information sensed by the one or more terminals and combined into the combined image.

Abstract
Provided are a system and method for a video call. The system for a video call includes one or more terminals configured to transmit images obtained by capturing video call users, and a video call control server configured to generate a combined image by combining the images transmitted by the one or more terminals, and transmit the combined image to the terminals. Here, the respective images are rotated according to information on postures sensed by the terminals and combined into the combined image.

17. A video call control server, comprising:
-
a communicator configured to receive respective orientation information on one or more terminals and original images obtained by capturing the corresponding video call users from the one or more terminals; an image rotator configured to rotate one or more of the original images required to be rotated to a reference orientation according to the orientation information among the original images received by the communicator to provide rotated images; and a combined image generator configured to generate a combined image by combining the original images not required to be rotated to the reference orientation and the rotated images, wherein the communicator transmits the combined image to the one or more terminals. - View Dependent Claims (18, 19)

22. A terminal used in a video call system, comprising:
-
a capturing unit configured to generate captured video images by capturing a video call user; an orientation sensor configured to sense a rotation state with respect to a previously set reference orientation; an image rotator configured to rotate the captured video images according to the rotation state, to provide rotated video images; and a video call unit configured to transmit the captured video images or the rotated video images based on the rotation state.
