ABSTRACT:
An image enhancement method and apparatus are provided for use with television equipment whereby a uniquely treated object within the field of a television camera is enhanced electronically for presentation on a television receiver to make it more readily observable to the viewer. A particular application involves treating, as by coating, a hockey puck, football or other target such as used in a sporting event that is being televised, with a material which radiates a spectral code or reflects light of a particular frequency not normally present to the same degree in ambient lighting conditions. The technique may be achieved with a single camera and a filter matched to the unique radiation from the target, or, a pair of ganged cameras where, one is of conventional design adapted to televise the entire scene and the other is particularly sensitive to the unique radiation of the target. Two images are formed in each case where the treated object is enhanced, either naturally or with a symbol, with respect to the overall scene making it easily observable to the viewer. A tracking system may be employed that is responsive to the position of the enhanced image whereby the cameras will automatically follow the puck, ball or the like.
