PURPOSE:To obtain a flicker-free three-dimensional TV image by using a magnetic sheet memory, and outputting signals, delayed when a right-image and a left- image signal are absent, then projecting two fields of the same image each for the left and right image. CONSTITUTION:As the output signal of a video tape recorder 10, a right-image and a left-image signal are outputted, field by field, alternately in every. The right image is projected by connecting an electronic switch 14 to a terminal (b) during a right-image output period and by inputting the signal to a TV receiver 16. During this period, the image is recorded on a one-field magnetic sheet memory 11. Then, the switch 14 is changed over to a terminal (a) to output the image during a left-image output period. Consequently, the same image from the receiver 16 is projected on a CRT18 by two fields at every time without absence. The left image is the same. For this purpose, two deflecting plates 20 and 21 having different angles of deflection are arranged in front of CRTs 18 and 19, and the images are synthesized through a half-mirror to obtain a flicker- free three-dimensional image through deflecting eyeglasses 23 and 24 conforming with the deflecting plates. |
