Television precision target shooting apparatus and method
First Claim
1. Apparatus for shooting at targets displayed on the screen of a raster scan display, comprising:
- a simulated weapon having means for sensing at a distance brightened raster scan segments on the screen of a raster scan display and trigger means; and
means responsive to a trigger pull for generating a signal to brighten the raster to thereby permit said simulated weapon to sense brightened raster scan segments.

Abstract
Simulated shooting at displayed images on the screen of a television receiver using an untethered, simulated gun provides indication on the screen of where the gun was pointed at the time of trigger pull. This is achieved by flashing the screen white subsequent a trigger pull in order that a photosensor within the gun will be responsive to short segments of horizontal raster lines such that by counting vertical lines and time intervals with respect to vertical and horizontal synchronization pulses, respectively, identification of where on the screen the gun was pointing is achieved, permitting a symbol to be displayed upon the screen at that location.

9. A method of shooting at targets displayed on the screen of a raster scan display with a simulated weapon having a trigger and electro-optical sensing means, comprising the steps of:
-
aiming at the displayed target; pulling the trigger; brightening the display screen; and sensing short segments of the brightened display raster. - View Dependent Claims (10, 11)

12. Apparatus for shooting at targets displayed on the screen of a raster scan display, comprising:
-
means for optically sensing short segments of a displayed television raster, said sensing means including an electro-optical sensor, switching means and means responsive to said switching means for enhancing the brightness of the raster such that said electro-optical sensor will respond thereto; and means coupled to said sensing means for resolving which of the raster segments were sensed thereby permitting a determination of where on the screen said sensing means was directed.

13. Apparatus for shooting at targets displayed on the screen of a raster scan display, comprising:
-
means for optically sensing short segments of a displayed complete television raster, said sensing means including an electro-optical sensor, switching means and means responsive to said switching means for enhancing the brightness of the raster such that said electro-optical sensor will respond thereto; and means coupled to said sensing means for resolving which of the raster segments were sensed thereby permitting a determination of where on the screen said sensing means was directed.
