Method of operating a video gaming system
A method of operating a video game system can include applying an optical filter in a field of view of a camera to filter out visible light and allow the camera to view non-visible light directed at a display screen positioned within the field of view of the camera. The method can also include processing the video output feed from the camera with a computer processor to identify a location of a non-visible light dot within the field of view of the camera that is projected onto the display screen by a light targeting peripheral unit. The method can also include calculating the location of the non-visible light dot within the field of view of the camera as a proportion of one or more dimensions of the field of view of the camera and translating the location of the non-visible light dot within the field of view of the camera onto a location on the display screen.

8. The method of claim 1 , wherein translating includes translating the location of the non-visible light dot onto the location on the display screen irrespective of the size of the display screen.
9. The method of claim 8 , wherein the display screen is a television.
10. The method of claim 1 , wherein the non-visible light dot is an infrared light dot.
11. The method of claim 1 , wherein processing includes searching in the digital video output feed the location of the non-visible light dot continually projected by the light targeting peripheral unit, and recording the position of the non-visible light dot upon actuation of an actuator of the light targeting peripheral unit.
12. The method of claim 1 , wherein processing includes searching the digital video output feed from the camera for the non-visible light dot that is projected by the light targeting peripheral unit onto the display screen upon actuation of an actuator of the light targeting peripheral unit.
13. The method of claim 1 , wherein processing the video output feed from the camera with a computer processor to identify a location of a non-visible light dot within the field of view of the camera includes filtering out intensity values of non-visible light below a predetermined threshold value.
14. The method of claim 1 , wherein processing the digital video output feed from the camera with a computer processor to identify a location of a non-visible light dot within the field of view of the camera includes filtering out non-visible light having a density of pixels below a threshold value.
15. A method of operating a video game system, comprising:
mechanically positioning an optical filter in a field of view of a camera to filter out visible light and allow the camera to view non-visible light directed at a display screen positioned within the field of view of the camera;
searching a digital video output feed from the camera with a computer processor to identify a location of a non-visible light dot within the field of view of the camera that is projected onto the display screen by a light targeting peripheral unit;
calculating the location of the non-visible light dot within the field of view of the camera as a proportion of one or more dimensions of the field of view of the camera;
translating the location of the non-visible light dot within the field of view of the camera onto a location on the display screen; and
initiating a recalibration of the camera to recalculate a boundary of the display screen in the field of view of the camera if a motion of the camera above a threshold amount is sensed with a motion sensor.
16. The method of claim 15 , wherein the display screen is a television.
17. The method of claim 15 , wherein the non-visible light dot is an infrared light dot.
18. The method of claim 15 , wherein the non-visible light dot is continually projected by the light targeting peripheral unit onto the display screen and searching includes tracking in the digital video output feed the location of the non-visible light dot and recording the position of the non-visible light dot upon actuation of an actuator of the light targeting peripheral unit.
19. The method of claim 15 , wherein the non-visible light dot is projected by the light targeting peripheral unit onto the display screen only upon actuation of the trigger, and searching includes searching in the digital video output feed the location of the non-visible light dot and recording the position of the non-visible light dot upon actuation of the actuator of the light targeting peripheral unit.
20. A method of operating a video game system, comprising:
positioning an optical filter in a field of view of a camera to filter out visible light and allow the camera to view non-visible light directed at a display screen positioned within the field of view of the camera;
searching a digital video output feed from the camera with a computer processor to identify a location within the field of view of the camera where a non-visible light dot is absent upon actuation of an actuator of a light targeting peripheral that projects non-visible light onto the display screen;
calculating the location within the field of view of the camera where the non-visible light dot is missing as a proportion of dimensions of the field of view of the camera;
translating the location of the absence of the non-visible light dot within the field of view of the camera onto a location on the display screen by applying the proportion of said dimensions of the field of view of the camera to corresponding dimensions on the display screen; and
