Patent ID: 8363056

Claim:
A content generation system that generates, by using a computer, a content regarding a lecture performed by a lecturer, comprising: a host terminal which the lecturer operates; and a content generation device connected to the host terminal, wherein the host terminal includes: a lecture material display unit that displays a material of the lecture on a display device; a display image transmission unit that transmits display image data displayed on the display device; and an index signal transmission unit that transmits an index signal to the content generation device when the lecturer inputs an instruction at a time that defines a break of the lecture during the lecture, and the content generation device includes: a lecturer imaging data generation unit that sequentially stores lecturer imaging data, in which a lecture scene of the lecturer is imaged, in a storage device of the content generation device; an animation data generation unit that generates, in synchronization with the lecturer imaging data, animation data from the display image data received from the host terminal, and stores the generated animation data in the storage device, the animation data generation unit converts the display image data into pieces of frame data and combines pieces of the frame data to generate the animation data; and a thumbnail data creation unit that creates an index as a break of the lecturer imaging data and the animation data at the time of receiving the index signal from the index signal transmission unit of the host terminal.
