Projection apparatus with video conference function and method of performing video conference using projection apparatus

A projection apparatus with a video conference function, comprising:

• a projection module;
• a network module, providing a network interface;
• a video-audio capturing module, electrically connected to the network module and configured to capture an image and voice of a local user, and accordingly generating a local video-audio data;
• a conference module, providing the video conference function;
• and
• a processor, electrically connected to the projection module, the network module, the video-audio capturing module and the conference module,
• wherein when the processor enables the video conference function of the conference module, the projection apparatus establishes a connection to a remote apparatus via the network interface, thereby receiving a remote video-audio data of a remote user from the remote apparatus and transmitting the local video-audio data to the remote apparatus,
• wherein the projection module is controlled by the processor so as to project an image corresponding to the remote video-audio data onto a projection surface.
