US 2014/0192162 A1 · SINGLE-EYE STEREOSCOPIC IMAGING DEVICE, IMAGING METHOD AND RECORDING MEDIUM

Abstract

After AE/AF/AWB operation, a subject distance is calculated for each pixel, and a histogram which shows the distance distribution is created based thereon. The class with the highest frequency which is the peak at the side nearer than the focus distance is searched based on the histogram and a rectangular area Ln which includes pixels which have a subject distance within the searched range is set. The average parallax amount Pn which is included in the rectangular area Ln is calculated and it is confirmed whether Pn is within a range of parallax amounts a and a−t1. In a case where Pn is not within a range of parallax amounts a and a−t1 which is set in advance, the aperture value is adjusted such that Pn is within the range of the parallax amounts a and a−t1.

Dependent claims

A single-eye stereoscopic imaging device comprising:

a single imaging optical system which includes a focus lens;
an imaging element which acquires a plurality of images by receiving light beams which each pass through different regions of the imaging optical system;
an aperture where it is possible to change an aperture value;
distance information acquiring unit which determines a distribution of distance information on subjects which are included in the plurality of images based on the plurality of images;
and
control unit which controls the aperture value and movement of the focus lens such that a parallax amount of an image region, which is a target of parallax adjustment, is a parallax amount within a predetermined range based on the distribution of the distance information.
