A composite lecture video generation system comprising:
- a mobile device operable to generate a screen capture video, based on display output being output from a display screen of the mobile device;
- a video camera module operable to generate an audio-visual recording of the display screen and of one or more physical objects positioned between the video camera and the display screen;
- and
- a composite lecture video generator operable to generate a composite lecture video, based on the screen capture video and the audio visual recording.
A composite lecture video generator comprising:
- a mobile device interface module operable to receive a screen capture video from a mobile device, the screen capture video being generated by the mobile device based on display output being output from a display screen of the mobile device;
- a video camera interface module operable to receive, from a video camera, an audio-visual recording of the display screen and of one or more physical objects positioned between the video camera and the display screen;
- and
- a processing module operable to generate a composite lecture video, based on the screen capture video and the audio visual recording.
A method for generating a composite lecture video, the method comprising:
- receiving a screen capture video from a mobile device, the screen capture video being generated by the mobile device based on display output being output from a display screen of the mobile device;
- receiving, from a video camera, an audio-visual recording of the display screen and of one or more physical objects positioned between the video camera and the display screen;
- and
- generating a composite lecture video, based on the screen capture video and the audio visual recording.
An article of manufacture including a machine readable storage device that stores a data structure produced using a process comprising:
- producing a first sequence of first frames that each encompass a view of a planar region;
- wherein producing the first frames includes recording within the first sequence of first frames a displaying of graphics within the planar region as the graphics are displayed from a viewpoint in which an object is disposed between the viewpoint and the planar region so as to obscure at least a portion of the displayed graphics;
- producing a second sequence of second frames that each encompass a view of the graphics within the planar region;
- wherein producing the second frames includes recording within the second sequence of second frames the displaying of graphics within the planar region;
- and
- superposing the graphics or portions thereof shown in the second sequence of second frames with respect to portions of the object shown in the first sequence of first frames that obscure such graphics or portions thereof.
An article of manufacture including a machine readable storage device that stores a data structure comprising:
- a sequence of frames that each encompasses a view of a planar region and that show graphics displayed within the region from a viewpoint in which an object is shown disposed between the viewpoint and the region and in which images of the graphics or portions thereof are shown superposed with respect to portions of the object that otherwise would obscure such graphics or portions thereof.
An electronic display device displaying a sequence of image frames that each encompasses a view of a planar region and that show graphics displayed within the region from a viewpoint in which an object is shown disposed between the viewpoint and the region and in which images of the graphics or portions thereof are shown superposed with respect to portions of the object that otherwise would obscure such graphics or portions thereof.
