Underwater camera
First Claim
1. An underwater camera comprising:
- a television camera which is divisable into plural portions;
a housing configured so as to encase the television camera in close proximity to interior housing walls and to provide waterproof protection in underwater environments;
a plurality of sections in the housing which are removably connected together and which are arranged so that each housing section is associated with at least one of the portions of the camera so as to provide access to components within said camera;
a substantially transparent member positioned in the housing so as to permit passage of light from exterior camera surroundings to the television camera within said housing;
a high quality camera lens disposed within the housing and connected to the television camera, said lens having a substantially infinite focal range so as to require substantially no adjustment of said focus while said television camera is in use;
means positioned in the housing for electrically connecting the television camera to an external device;
means contained within the housing and contacting the television camera for supporting and stabilizing said camera within said housing; and
means electrically connected to the television camera for monitoring television pictures produced by said camera.

Abstract
An underwater color television camera system for use in high pressure or dense shielding applications. The system includes a spread tube color television camera encased in a three-segment housing designed to provide quick access to and interchangeability of camera parts, while also providing protection to the camera from water pressure at depths of over 2500 feet below water surface. A television viewfinder is affixed to the camera housing for use during manual operation by divers. A control center which includes computer devices is remotely connected by coaxial or triaxial cable to the camera so as to permit surface control and monitoring of numerous camera operations. Camera operations and applications are capable of enhancement by use of computer generated graphics, computer navigation assistance, and computer aided visual communication with divers.
