Therefore, simply increasing the number of interpolated images can only narrow the area of ​​one image, and even if the interposed image pair can be seen, the stereoscopic baseline hardly changes

[0055] figure 1 It is a diagram for explaining the first embodiment of the stereoscopic image generating method of the present invention. Here, a case where four images with parallax are used will be described as in the description example of the background art. In the case of using 4 images with parallax, as in the past Figure 4 It is shown that the image attachment surface of each lens is divided into four equal parts and the respective images are distributed, but in the present invention, the occupation width of each image with parallax becomes larger as it goes toward both ends, and the occupation width of each image with parallax becomes larger as it goes toward the middle. Occupy the smaller the width. Attachment of the image at this time can be performed automatically as one of computer-controlled automatic procedures.

[0056] figure 1 In the case of equal occupancy, the areas of the first image P1 and the fourth image P4 are widened to about 1.33 times, and on t...

[0062] image 3 It is a figure for demonstrating the 2nd embodiment of the stereoscopic image generation method of this invention. This implementation is based on Image 6 The method of interpolating images with parallax as shown is based on a method of forming a stereoscopic image.

[0063] exist Image 6 In the present invention, the intermediate images P2 and P3 are generated by interpolation in such a manner that the cameras (lenses) are arranged at equal intervals, but in the second embodiment of the present invention, the cameras (lenses) are arranged at intervals between the second camera C2 and the third camera C3 Interpolation generates intermediate images P2a and P3a (L1=L3

[0064] More simply, in the second embodiment of the present invention, the interpolation interval is wider at the center an...

Abstract

The invention provides a method and an apparatus for generating stereoscopic images. Even a small photo (image) can also get more into the deep by using a parallax general purpose 3D camera to shoot. Parallax in the configuration of the double convex lens on the back of multiple images or make images of optical input, the generated images make the eyes watch from the side facing the eye with a three-dimensional image, at the moment, at least part of the adjacent image on multiple images with parallax are configurated in a manner of more to the ends of the parallax image occupies a width, the more to the central configuration image of the parallax image occupies the width of the smaller, for example, compared with an equality possession condition, the areas of the first image and the fourth image are expanded to about 1.33 times, on the contrary, the areas of the second image and third image region are narrowed to about 0.67 times. As a result, the occupied width of the first image and the fourth image is two times of the occupied width of the second image and third image.

Description

technical field [0001] The present invention relates to a stereoscopic image generation method and device thereof, and in particular to a stereoscopic image capable of obtaining a stereoscopic image with a greater sense of depth even from photographs (images) captured with a general-purpose three-dimensional (3D) camera with a small parallax. Image generating method and device thereof. Background technique [0002] A lenticular lens refers to a member in which semiconical elongated lenses are arranged side by side in a plate shape (sheet shape). If a plurality of different images are arranged in a thin rectangle along the longitudinal direction of each lens (semi-conical protrusion) on the back of the lenticular lens, different images can be seen depending on the viewing angle. Utilizing this feature, if the images captured by shooting the subject from different angles are configured, each image with parallax can be seen with the left and right eyes. This makes it possible...
