Stereoscopic image capturing device and method of controlling thereof

摘要

Feature points are extracted from left and right viewpoint images (Step S12), and the amount of parallax of each feature point is calculated (Step S13). The maximum amount of parallax on a near view side and the maximum amount of parallax on a distant view side are acquired from the calculated amount of parallax of each feature point (Step S14). The maximum display size which enables binocular fusion from a supposed visual distance when a stereoscopic image based on the left and right viewpoint images is displayed on a stereoscopic display is acquired on the basis of at least the maximum amount of parallax on the distant view side (Step S15). The acquired maximum display size is recorded along with image information (Step S16). The image reproduction device which reads the 3D image file recorded in this way can be appropriately displayed on the basis of the maximum display size.

1. A stereoscopic image capturing device comprising:
image capturing unit for acquiring a plurality of viewpoint images of the same subject from a plurality of viewpoints; parallax amount calculation unit for calculating the amount of parallax representing the amount of deviation between feature points having common features from the plurality of acquired viewpoint images; maximum parallax amount acquisition unit for acquiring the maximum amount of parallax on a distant view side from the calculated amount of parallax of each feature point; maximum display size acquisition unit for acquiring the maximum display size enabling binocular fusion when a stereoscopic image based on the plurality of viewpoint images is displayed on a stereoscopic display on the basis of the acquired maximum amount of parallax on the distant view side; recording unit for generating a three-dimensional image file in which the plurality of viewpoint images are recorded, and recording the three-dimensional image file in a recording medium, the recording unit recording the plurality of viewpoint images in the three-dimensional image file and recording the maximum amount of parallax on the distant view side and the maximum display size in the three-dimensional image file as auxiliary information; representative image setting unit for setting one of N (N is an integer equal to or greater than 3) viewpoint images acquired by the image capturing unit as a representative image; and display image generation unit for generating display images of image size smaller than the viewpoint images on the basis of the N viewpoint images, wherein the maximum parallax amount acquisition unit acquires (N−1) maximum amount of parallax on the distant view side in association with two images of different combinations of the representative image and (N−1) viewpoint images other than the representative image from the N images, the maximum display size acquisition unit acquire (N−1) maximum display sizes on the basis of the acquired (N−1) maximum amount of parallax on the distant view side, the recording unit records the acquired (N−1) maximum amount of parallax and maximum display sizes on the distant view side in the three-dimensional image file as the auxiliary information, and the recording unit records the display images in the three-dimensional image file.
