Prior Art FIG. 8 is a system diagram showing the configuration of a typical prior art. The light from the subject 1 is imaged by the reflecting mirrors 2 and 3 on the left eye imaging area 5 of the imaging surface 4 of an imaging means such as a television camera, and the left eye information is formed.
It includes right eye information that is reflected by the reflecting mirrors 6 and 7 and is imaged on the left eye imaging area 5 of the imaging surface 4 and the right eye imaging area 8 adjacent in the left and right direction.

FIGS. 9 and 10 are diagrams for explaining the imaging state of the left eye information and right eye information of the subject 1 on the imaging surface 4. FIG. In the conventional technology having the above-described configuration, the left-eye imaging region 5 and the right-eye imaging region 8 that are adjacent in the left-right direction on the imaging surface 4 are juxtaposed. Furthermore, in the conventional shape of the imaging surface 4, the ratio of length and width (in the vertical and horizontal directions in FIG. 8) is set to 3:4. The ratio will be 3:2.

Problems to be Solved by the Invention In such a conventional technique, the characteristics of the reflectors 2, 3; 6, 7, etc. are As a result, an overlapping region 9 in which images overlap or are blurred is generated. Therefore, the imaging surface 4 shown in FIG.
If the optical image formed on the image is displayed as it is, it will confuse the viewer's vision. Further, due to the generated overlapping area 9, there is a problem that the area that can be effectively used on the imaging surface 4 is narrowed.

Furthermore, if you try to take out only the left eye imaging area 5 and display it on the display screen of the television receiver (the aspect ratio is set to 3:4), the vertical and horizontal ratio of the left eye imaging area 5 as described above will change. The ratio of the dimensions (3:
2), the display area 10 shown by the two-dot chain line in FIG. 10 must be selected, and the remaining image in the left eye imaging area 5 cannot be displayed.

The stereoscopic imaging device 11 includes the imaging device 12 described with reference to FIG. The optical image formed on the imaging surface 13 of the imaging device 12 is
It is read by an electron beam irradiated by horizontal and vertical deflection coils 23.

The video signal from the imaging surface 13 is amplified by a video signal amplification section 24 and sent to a video signal processing circuit (hereinafter referred to as a processing circuit) 25, where processing such as adding a synchronization signal and generating a color difference signal is performed. , the output of the video signal S1 is obtained.

Of the horizontal and vertical deflection coils 23, the horizontal drive pulse H generated from the horizontal oscillation section 26 is applied to the horizontal deflection coil as a horizontal deflection signal via the horizontal deflection signal output section 27. Also, in the vertical deflection coil, the vertical drive pulse V generated from the vertical oscillation section 28 passes through the vertical deflection signal output section 29, and then the control signal S3, which will be described later, is added to the vertical deflection coil by the control signal adder 30 to form a composite signal. It is given as a vertical deflection signal S4.

The control signal adder 30 receives drive pulses H,
V, and a control signal S3 from a control signal generating section 31 that generates a control signal S3 having a waveform as described later.

FIG. 2 is a block diagram showing the configuration of the control signal generating section 31 of FIG. 1, and FIG. 3 is a waveform diagram showing the waveforms of the input signal and output signal of the control signal generating section 31, respectively. The configuration of the control signal generator 31 will be described with reference to FIGS. 1 to 3. The control signal generator 31 includes a one-shot vibrator 32 to which the vertical drive pulse V from the vertical oscillator 28 is input, and a D-type flip-flop circuit (hereinafter abbreviated as flip-flop) 33.

The one-shot vibrator 32 is supplied with a vertical drive pulse V of the waveform shown in FIG.

A resistor R1 having a resistance value R and a capacitor C1 having a capacitance C are connected to the one-shot vibrator 32, and a time constant τ τ=RC... ...(1) is set as described below. Here, the flip-flop 33 outputs a signal S3 shown in FIG. 3(2) in which the output of the one-shot vibrator 32 is synchronized with the horizontal drive pulse H. At this time, the delay time W1 that is equal to or approximately equal to the delay time τ is:
The time is set to about half the period W2 of the vertical drive pulse V.

FIG. 5 is a waveform diagram illustrating the operation of the three-dimensional image device 11 having the configuration shown in the first diagram. The operation of this embodiment will be described with reference to FIGS. 1 to 5. The vertical deflection signal output section 29 includes a vertical transmission section 2.

is input, and a vertical deflection signal with the waveform shown in Figure 5 (1) is generated.
Output S2. Here, in one field period W2 of the vertical deflection signal S2 shown in FIG. 5(1), the period
W3 is a blanking period, and period W4 is a vertical scanning period.

On the other hand, the control signal generator 31 outputs the control signal S3 shown in FIG. 5(2) as described above, and the control signal adder 30 outputs the vertical deflection signal S2.
and is output as a composite vertical deflection signal S4 having the waveform shown in FIG. 5(3).

Figure 6 shows the composite vertical deflection signal S4 shown in Figure 5(3).
FIG. 2 is a diagram illustrating a scanning state of the imaging surface 13 using the . On the imaging surface 13 in FIG. 6(2), the left eye imaging region 20b and the right eye imaging region 20a described with reference to FIG. 4 are arranged adjacent to each other in the vertical direction, and between these In the boundary region 20c, even in the imaging state according to the present embodiment shown in FIG. 4, overlapping images and blurring are generated.

In the scanning of the imaging surface 13 shown in FIG. 6, the scanning of the left eye imaging area 20b progresses, and from the start time t0 of the composite vertical deflection signal S2 shown in FIG. 5(1), referring to FIG. When the explained delay time W1 has elapsed, the composite vertical deflection signal S4 shown by line 1 in FIG. Scanning is started from the downstream side in the vertical scanning direction (downward side in FIG. 6) by a larger pitch P1. Therefore, by setting the delay time W1 so that the period of pitch P1 includes the boundary area 20c, right eye imaging can be performed without scanning the boundary area 20c during scanning of the imaging surface 13. The region 20a and the left eye imaging region 20b can be scanned.

Therefore, in the stereoscopic video device 11 of the present embodiment, the overlapping area 9 in the prior art described with reference to FIG. can be prevented from occurring. Further, the ratio of the length and width of each of the right eye imaging region 20a and the left eye imaging region 20b shown in FIG. 4 was set to be 2:3. With this setting, for example, when only the left eye imaging area 20b is displayed on a display screen with a normal vertical and horizontal length ratio of 3:4, the image will be displayed as shown in FIG. The length to width ratio is 3:4.5
Therefore, as pointed out in the prior art, it is possible to avoid not using a wide range of images in the imaging area 5.

Effects As described above, according to the present invention, a three-dimensional image device is constructed including an imaging means and a scanning means. The imaging means has an imaging surface on which a plurality of optical images having binocular parallax are formed in a predetermined array. The scanning means includes a horizontal deflection signal output means for realizing horizontal scanning of the imaging surface of the imaging means, a vertical deflection signal output means for realizing vertical scanning, and a vertical deflection signal from the vertical deflection signal output means. A control signal superimposing means for superimposing a control signal that prevents scanning of a predetermined portion according to a predetermined arrangement pattern is included.

Therefore, the imaging plane corresponding to this control signal is not scanned, and it is possible to prevent overlapping optical imaging and blurring in the vicinity of the boundary of the same area of the imaging plane including the vertical position.
