PURPOSE:To attain effective, splendid and natural three-dimensional vision by driving shutter mechanism in relation to multiplied deflection signal to provide time difference in pictures supplied continuously to right and left eyes. CONSTITUTION:Signals received by a tuner 10 are supplied to a field memory 12 through a video intermediate frequency circuit 11. Signals from the circuit 11 are supplied to a synchronizing separator circuit 13, and separated synchronizing signals are supplied to a controlling circuit 14 to control reading and writing of the memory 12. Signals of the same field are formed repeatedly by reading and writing of the memory 12, and at the same time, vertical and horizontal deflection signals are multiplied, and the same field is displayed plural number of times in an image receiving tube. Signals from the circuit 14 are supplied also to a driving circuit 19, and driving signals that alternate every 1/120sec are formed, and shutter mechanisms 7L, 7R provided just front of right and left eyes are driven by the driving signals. |
