Conventionally, when photographing a stereoscopic image includes a two imaging portion, a right-eye image Te cowpea the first imaging unit, have taken the left-eye image by the second imaging unit. At this time, to form a cross-point (Con purge Enns point) CP which is convergent point crossed optical axis of the first imaging section and the optical axis of the second imaging unit on the imaging target surface, taking a stereoscopic image are doing. The technique for measuring the distance from the imaging target surface to the photographing apparatus (i.e., the distance to CP) have been proposed.

However, JP-A-2 0 0 1 2 3 1 0 5 5 No. inventive technique described in Japanese, even when measuring the distance to CP when taking a stereoscopic image, the distance to the CP (CP information) It was never recorded with the standing body image. Further, even if the CP information is recorded, when the stereoscopic video is reproduced, CP information was not being used as a signal as a reference three-dimensional effect.

In particular, to play the same content in different display device screen size, since the parallax amount of the left and right Film images are different, the pop-out amount from the screen by the screen size is changed, it is impossible to obtain a natural stereoscopic image problem there is. In other words, large Amu - stereoscopic video content that Zumento facility was used as a target, so the content is produced by assuming a large screen size that will be screened, the correct three-dimensional if it is not theater or devices that have the same screen size feeling can not be obtained, in addition to the three-dimensional effect and the screen size is large or discomfort too strong, was unsatisfactory less three-dimensional effect and the screen size is small.

Thus the prior art, since there is no way to adjust the time parallax amount determined by the produced content during reproduction, the distance between the position and the screen for viewing, the viewer, forced to adjust the stereoscopic effect obtained did not.

In the case of broadcasting stereoscopic video, automatically automatically no way to adjust the stereoscopic effect corresponding to allowed by the stereoscopic image to lifting one stereoscopic image display device an unspecified number of viewers and a variety of screen sizes, not it is difficult to broadcast a stereoscopic image for a specific number.

FIGS. 3 to 5 are in the embodiment of the present invention, is a diagram for explaining the adjustment of the by that three-dimensional effect to the change in the relative positions of the left and right images.

Figure 3 shows a case where the right eye image and the left eye image is positioned at the time of shooting.

Orijinaru stereoscopic image 3 0 0, left-eye videos 3 0 1 and in One Manzanillo and right-eye image 3 0 2 has been configured. In this state, the position of the left-eye image 3 0 1 and the right-eye image 3 0 2 is in a position equal to the time of shooting, the relative positions of the left and right images are correctly reproduced. Thus, the cross point 3 0 3 is in a position at the time of shooting (the original cross point). Figure 4 shows a state of displaying by shifting the right-eye image to the right.

Stereoscopic video 3 1 0 that is composed of a left-eye image 3 1 1 and the right-eye image 3 1 2. For read timing of the left-eye image, to slow down the reading timing of the right-eye image (delaying the phase of the right eye signal), when displaying by setting the offset to be shifted the right-eye image on the right side of the left-eye image, gaze viewed left-eye image with the left eye, intersect at the back side of the display screen and the line of sight viewed right eye image with the right eye, the cross point 3 1 3 moves farther than the position at the time of shooting. Therefore, than the original stereoscopic image, it weakened jump out of sense of depth is emphasized, and away image in the distance across.

Figure 5 shows a state of displaying by shifting the right-eye image to the left.

Stereoscopic video 3 2 0 that is composed of a left-eye image 3 2 1 and the right-eye image 3 2 2. For read timing of the left-eye image, and quickly read timing of the right eye image (advancing the phase of the right eye signal), when displaying by setting the offset to shift the right-eye image to the left with respect to left-eye image, the left eye gaze viewed left-eye image in, the line of sight viewed right-eye image with the right eye intersects with the front side of the display screen, the cross point 3 2 3 is front of the position at the time of shooting. Therefore, than the original stereo image, are strong jumps out of adjustment, weakened sense of depth, the image close to the front as a whole.

Incidentally, when displaying the left-eye and right-eye images by setting the offset, although one each of the right and left end portions of the left and right eye image is absent, the image of the vicinity of the area where the image is insufficient in the lateral direction enlarged and may be displayed. At this time, based on the aspect ratio of the display screen (Asupeku Ratio), and displays the expanded image in the vertical direction. Specifically, the offset state as shown in 4, but lacking the left end of the right-eye image, and displays the right-eye image by extending the left edge of the image of the right eye image to the left portion of the display screen. Further, in the offset state as shown in FIG. 5, but lacks the right edge of the right-eye image, and displays the right-eye image by extending the right edge of the image of the right eye image to the right edge of the display screen. In together when extending the sides of these offset the image, the image of the side in aspect ratio of the display screen also extending in the longitudinal direction, by displaying an enlarged image, offset from the display screen the image is missing, nothing movies image without causing areas that are not displayed (area displayed on black) can be displayed a natural stereoscopic image.

Next, describing calculation of offset amount of the left and right eye images.
