Abstract An improved, self-contained, remotely controlled color television system is disclosed. The system utilizes a small head mounted television camera which is adapted to transmit a picture of the operations carried on by the wearer of the camera to be remotely viewed and/or recorded by a third party. The focusing and aiming of the camera is remotely controlled from a console equipped with controls and a television monitor. An illumination system is provided which utilizes a dual beam, the convergence and elevation of which is controlled by the wearer. The illumination is fixed to the head mounting so as to follow the head movements of the wearer. The dual beam of the illumination system enables the area desired to be illuminated by the wearer to be so illuminated virtually without shadows and without interference to his field of view. The video image reproduced by the system is of a high quality which makes it quite useful for teaching and demonstrating such things as delicate surgical procedures of the type often found in dental, abdominal, cardiovascular and neurosurgery. Control of the illuminaton system by the wearer enables him to work without distraction caused by remote control of the illumination system. A second stationary mounted camera may be added to this system to provide additional coverage.
In a remotely controlled head-mounted visual apparatus for viewing manual operations carried on by the wearer, said apparatus including camera means for generating signals representative of a visual image received, aiming and focusing means for said camera means, remote control means for controlling said aiming and focusing means, means for reconverting said signals to reproduce said visual image, means for transmitting said signals from said camera means to said means for reconverting, real-time viewing means for viewing said reconverted image, and mounting means for mounting said camera, aiming and focusing means on the head of said wearer, the improvement comprising: forward directed illumination means fixed on said head-mounted apparatus in a manner such that the location of the field lighted thereby is determined locally by the attitude of the head of said wearer.
