Abstract
A method is described comprising: applying phosphorescent paint to specified regions of a performer's face and/or body; strobing a light source on and off, the light source charging the phosphorescent paint when on; and strobing the shutters of a first plurality of cameras synchronously with the strobing of the light source to capture images of the phosphorescent paint, wherein the shutters are open when the light source is off and the shutters are closed when the light source is open.
Claims52
A method comprising:
- applying phosphorescent paint to regions of a performer's face and/or body;
- strobing a light source on and off, the light source charging the phosphorescent paint when on;
- and
- strobing the shutters of a first plurality of cameras synchronously with the strobing of the light source to capture sequences of images of the phosphorescent paint (“glow frames”) as the performer moves or changes facial expressions during a performance, wherein the shutters are open when the light source is off and the shutters are closed when the light source is on.
1 more element
A system comprising:
- a synchronization signal generator to generate one or more synchronization signals;
- a light source configured to strobe on and off responsive to a first one of the one or more synchronization signals, the light source charging phosphorescent paint applied to regions of a performer's face and/or body for a motion capture session;
- and
- a plurality of cameras having shutters strobed synchronously with the strobing of the light source to capture sequences of images of the phosphorescent paint (“glow frames”) as the performer moves or changes facial expressions during a performance, wherein the shutters are open when the light source is off and the shutters are closed when the light source is on.
1 more element
A method comprising:
- applying phosphorescent paint to regions of a face and/or body or a performer;
- strobing a light source on and off, the light source charging the phosphorescent paint when on;
- and
- strobing the shutters of a plurality of cameras synchronously with the strobing of the light source to capture a sequence of images of the phosphorescent paint (“glow frames) and images of the object in motion (“lit frames”), wherein the shutters are closed and then opened when the light source is off to capture the glow frames and then closed and then opened when the light source is on to capture the lit frames.
