Abstract

PROBLEM TO BE SOLVED: To solve a problem that an observer requires advanced training for transferring focuses of both eyes in the depth direction of a screen for the purpose of stelephonically viewing the two screens of stereogram animation screens with naked eyes in the conventional manner. SOLUTION: A single circumferential image and a noticing image are arranged in one screen before distribution the two screens of the stereogram animation screens, the noticing image is divided into the images for right and left eyes, the images are gradually changed to far images and the two screens of the stereogram animation screens are distributed at a point of time when the focuses of the observer can stereophonically view an infinite far point.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention utilizes the stereoscopic effect of a stereogram to perform stereoscopic viewing using a parallel method or a crossing method on two screens arranged side by side for the right eye and the left eye. The present invention relates to a naked-eye stereoscopic video image screen.

[0002]

2. Description of the Related Art A conventional method of using a lenticular lens called a lenticular lens to stereoscopically view a stereogram moving image screen with the naked eye. There has been a method of staring at two screens arranged side by side for the right eye and the left eye side by side by a parallel method or a crossing method for stereoscopic viewing.

[0003]

However, the lenticular lens is very expensive. On the other hand, the stereoscopic method using the two screens by the parallel method or the crossing method is inexpensive, but the observer stereoscopically views the object. In order to do this, the focus of both eyes must be moved in the depth direction, which is not the surface position of the screen screen, but the images of the surroundings of the object are also reflected in both eyes of the observer, and the focus of both eyes should be focused at the surface position of the screen. To
It required advanced training to move the focus in the depth direction of the screen.

[0004]

According to the present invention, a gaze image A is arranged in a single screen screen S, a surrounding image B is arranged around the gaze image A, and the surrounding image B is blurred or swung. To make it difficult to specify the surrounding shape. Gaze image A
Is divided into partial images A1 and A2 for the right eye and the left eye that are moved in the depth direction from the screen position while gazing by changing the intensity of the brightness, and is reduced according to the distance from the screen and at the same time left and right. The distance between the partial images A1 and A2 is widened to change to long-distance projection.

As a result, it becomes difficult for the observer's eyes to gaze at the surrounding image, and the eyes are in a state of gazing at the partial images A1 and A2.
The gazed images of A1 and A2 are observed as a stereoscopic image with a focus in the depth direction of the screen screen as the only gazed image A. When the distance between the partial images A1 and A2 becomes approximately half the screen width of the screen, the images of A1 and A2, which are visible to the left and right eyes of the observer, are focused at infinity and stereoscopically viewed. Become.

[0006] In this state, by distributing a moving-image stereogram screen consisting of two screens, a right-eye screen R and a left-eye screen L, to the screen screen S, the observer can display the distributed moving-image stereogram screen as it is. You can continue to see stereoscopically. By this means, the focus can be moved in the depth direction of the screen to enable stereoscopic viewing without requiring high-level training, and the above problem is solved.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a moving image screen for stereoscopic vision with naked eyes according to the present invention has a gazing image A arranged in a screen screen S of one screen as shown in FIG. The image B is arranged and the surrounding image B is blurred to make it difficult to specify the surrounding shape. The gaze image A is strongly gazed by inserting an image that repeatedly sparks.

As the second stage, as shown in FIG.
It is divided into right-eye and left-eye partial images A1 and A2, moved from the screen position in the depth direction, and reduced in accordance with the distance from the screen, while at the same time widening the interval between the partial images A1 and A2 to the far side. I will change it to a movie. This makes it difficult for both eyes of the observer to gaze at the peripheral image B and is in a state of strongly gazing at the partial images A1 and A2.

The gazed images A1 and A2 are observed as a stereoscopic image as the only gazed image A with the focus in the depth direction of the screen. As the third step, as shown in FIG. 3, when the horizontal distance between the images A1 and A2 becomes approximately half the screen width of the screen, the images A1 and A2 seen by the left and right eyes of the observer are at infinity position. Is focused and the stereoscopically viewed image A is displayed.

As the fourth step, as shown in FIG.
The images of A1 and A2 are focused on the position at infinity and are stereoscopically viewed as a gaze image A. In that state, by distributing a right-eye screen R and a left-eye screen L, a moving-image stereogram screen in the screen screen S,
The observer can continue to stereoscopically view the distributed stereogram screen for moving images. This means solves the above problem.

[0011]

As described above, according to the invention of claim 1, when the observer observes the screen of one screen, the observer naturally sees a stereogram of two screens. Advanced training for moving the focus in the depth direction of the screen while watching two screens is no longer necessary. Claim 2
According to the invention of paragraph,

By inserting a sparking image into the gaze image A repeatedly, the gaze image A is strongly gazed so that the observer can easily move the focus. The present invention can be applied to a film image screen as well as an electronic image screen.
