摘要

Provided is a virtual classroom lecture apparatus facilitating configuring a lecture screen by a lecturer during a lecture. The virtual classroom lecture apparatus comprises: at least one camera for photographing a lecturer; at least one content input unit for providing lecture content; a virtual studio generating unit for combining images which are stored in a database and forming a virtual studio; an input device for selecting the configuration of the lecture screen which the lecturer wants; a rendering unit for combining the images provided by the camera, content input unit, and virtual studio generating unit depending on the choice made by the input device; and a display device for displaying the image outputted by the rendering unit. [Reference numerals] (2) Background image;(3) Laptop-Camera;(AA) Extract a lecturer image;(BB) Start;(CC) End;(S100) Step of selecting, editing and setting a virtual classroom;(S200) Photograph a lecturer who is teaching using a camera;(S300) Extract a lecturer layer by chroma keying from the photographed lecturer image.;(S400) Generate a final image by combining the lecturer layer and a lecture materials layer displaying more than one lecture materials such as an external camera or laptop screen in real time and output the image to a display device;(S500) Generate an additional note layer using the notes made by the lecturer, if the lecturer makes the notes using a tablet pc, and output the note layer to the display device;(S600) Adjust the sizes, positions or angles of the lecture materials layer, lecture layer, and note layer and recombine the layers if the lecture operates a screen configuration switching device, and output the new image, wherein the sizes, positions or angles of the lecture materials layer and note layer are adjusted at the same ratio;(S700) Detect motions of a button, a mouse, and a table pc pointer and a change in a mouse moving time, and switch a combined screen and a screen configuration in order to automatically switch a screen in an automatic screen switching mode
