Abstract

According to the present invention, an electronic teacher desk system comprises a teacher desk, a transparent board, a camera, a display device, and a system controller. The transparent board is placed on the teacher desk and is formed to be able to be written. The camera is placed on the back of the transparent board and obtains a written board image written on the transparent board. The display device is placed on the back of the transparent board, projects a lecture material image onto the transparent board whenever the lecture material image is displayed, and allows the camera to obtain the written board image of the transparent board in a transparent state whenever the lecture material image is not displayed. The system controller controls whether or not to transmit the lecture material image to the display device. Each time the lecture material image is not transmitted to the display device, the system controller receives the image obtained from the camera, extracts the written board image by removing the background and reversing the left and right sides, composes the extracted written board image with the lecture material image, and outputs the composite lecture image. According to the present invention, the convenience of a lecture can be increased, and the control of the lecture can be maximized.
