Abstract

PURPOSE:To provide a stereoscopic image having presence by respectively displaying pictures for right and left eyes while laterally bisecting the display screen of a large aspect ratio. CONSTITUTION:A monitor 22 with the display screen of an aspect ratio 16:9 is laterally bisected, a right picture R is displayed on a left display screen 22L, and a left picture L is displayed on a right display screen 22R. Further, linear polarizing filters 23A and 23B not to be permeable each other are arranged on the surface corresponding to the pictures R and L. This monitor 22 is observed through spectacles 30 for stereoscopic image provided with a filter 23A for right eye, filter 23B for left eye and the same polarizing direction filters 33 and 34. Thus, the picture through the filters 33 and 34 is turned to just the left and right side halves of pictures R and L. Therefore, since the picture R is observed just with the right eye and the picture L is observed just with the left eye in the pictures of different view points provided by a camera 11 for stereoscopic image when observing the monitor 22 while using the spectacles 30, the stereoscopic image synthesizing the pictures R and L can be observed visually at the center of the monitor 22.

(3-12) In the above embodiment, the case of transmitting a high definition television signal using the broadcasting satellite 15B has been described, but the transmission medium is not limited to this, and as shown in FIG. 22, for example. The present invention can also be applied to the case of recording and / or reproducing a high-definition television signal using a high-definition video tape recorder (VTR).

That is, in FIG. 22, the data PIC1 for one screen (one frame) is divided into four by making the MUSE decoder 41 thin out the data of the high definition television signal obtained by the stereoscopic video camera 11.
Split (PIC1A, PIC1B, PIC1C, PIC1
D) and record this on the magnetic tape TAPE.

When this magnetic tape TAPE is reproduced on the high-definition video tape recorder HDVTR, the 4-divided image data PI is transmitted via the MUSE decoder 42 attached to the high-definition video tape recorder HDVTR.
The reproduced images PIC2 can be obtained by reproducing C1A to PIC1D.

(3-13) In the above embodiment, the case where the polarization filters having the polarization planes orthogonal to each other are used has been described. However, the present invention is not limited to this, and circular polarization filters having different rotation directions are used. You may use it.

As described above, according to the present invention, the left and right images are respectively displayed by separately displaying the images with different viewpoints in the respective display areas formed by horizontally dividing the predetermined display screen into two. It is possible to avoid double overlapping, which makes it possible to obtain a stereoscopic image with a display image that is easier to see without a sense of discomfort, and divides the display screen with a large aspect ratio into two in the horizontal direction to display the image for the right eye. Also, by displaying the image for the left eye, it is possible to obtain a stereoscopic image having a realistic sensation with a sufficient aspect ratio.
