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. ## Claims ### Claim 1 A method of operating a video game system, comprising: 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; processing 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. ### Claim 2 (depends on 1) The method of claim 1, wherein applying the optical filter includes mechanically positioning the optical filter in the field of view of the camera. ### Claim 3 (depends on 1) The method of claim 1, wherein applying the optical filter includes turning on an electronically switchable optical filter. ### Claim 4 (depends on 1) The method of claim 1, wherein processing the digital video feed from the camera includes continuously processing the video output feed. ### Claim 5 (depends on 1) The method of claim 1, wherein said processing is performed at least in part by the camera. ### Claim 6 (depends on 1) The method of claim 1, wherein said processing is performed at least in part by a console of the video game system. ### Claim 7 (depends on 1) The method of claim 1, wherein translating the location of the non-visible light dot within the field of view of the camera onto the location on the display screen includes applying the proportion of said one or more dimensions of the field of view of the camera to corresponding dimensions on the display screen. ### Claim 8 (depends on 1) 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. ### Claim 9 (depends on 8) The method of claim 8, wherein the display screen is a television. ### Claim 10 (depends on 1) The method of claim 1, wherein the non-visible light dot is an infrared light dot. ### Claim 11 (depends on 1) 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. ### Claim 12 (depends on 1) 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. ### Claim 13 (depends on 1) 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. ### Claim 14 (depends on 1) 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. ### Claim 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. ### Claim 16 (depends on 15) The method of claim 15, wherein the display screen is a television. ### Claim 17 (depends on 15) The method of claim 15, wherein the non-visible light dot is an infrared light dot. ### Claim 18 (depends on 15) 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. ### Claim 19 (depends on 15) 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. ### Claim 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 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.
