PURPOSE: To record/reproduce a solid picture into high quality. CONSTITUTION: Double scan cameras 101 and 102 supply the picture signal (double scan signal) of 525×60 frames/second to a 3D encoding circuit 103 in accordance with a synchronizing signal from VTR 104 of two systems simultaneous recording/reproduction. In the circuit 103, a selection circuit 108 switches two double scan signals in a frame unit and supplies them to an interlacing conversion circuit 110 through an A/D converter 109. The circuit 110 interlacing- converts the double scan signals into an odd field and an even field, and supplies an odd field signal to the channel 1 of VTR 104 and an even field signal to a channel 2. A 3D decoding circuit 105 converts the reproduction signal of two channels from VTR 104 into the double scan signal of one frame and supplies it to a double scan monitor 106. A 3D glass driver circuit 113 drives a 3D glass 107 in accordance with a vertical synchronizing signal from VTR 104. |
