Abstract

A portable television camera and recording device is provided for generating, monitoring, and recording still and motion picture information. The device is provided within a single housing permitting the housing to be pointed at an object or scene to be recorded. A television camera or flying spot scanner, a television recorder such as a magnetic tape video recorder, and a visual monitor such as a cathode ray tube are supported within the housing. Manually operable controls such as switches which may be selectively actuated to perform such functions as monitoring and/or recording are provided. The major components of the portable unit, such as the television camera, magnetic tape recorder, monitor and electronic control units, are preferably modular and capable of being removed and replaced without difficulty. In one form, a trigger operated switch may be operated in one of two modes effecting either single frame television signal recording or multiple frame motion picture television signal recording and playback.
