IMAGING DEVICE, IMAGING METHOD AND PROGRAM STORAGE MEDIUM

摘要

An imaging device includes: imaging units that capture a same object of imaging from different viewpoints; a detection unit that detects a subject from respective frame images; a range computing unit that, if plural subjects are detected, computes a range expressed by a difference between a maximum value and a minimum value among values relating to distances between the detected subjects and the corresponding imaging units; an adjusting unit that, if the difference between a range of a specific frame and a range of a frame immediately before or after the specific frame exceeds a threshold value, adjusts the range of the specific frame such that the difference is reduced; a parallax amount computing unit that computes a parallax amount corresponding to the adjusted range; and a stereoscopic image generation unit that generates a stereoscopic image from captured viewpoint images based on the computed parallax amount.

1. An imaging device comprising:
a plurality of imaging units that capture, continuously and one frame at a time, a same object of imaging from a plurality of different viewpoints respectively; a detection unit that detects a subject from respective images of the frames captured by any one of the plurality of imaging units; a range computing unit that, if a plurality of subjects are detected by the detection unit, computes a range expressed by a difference between a maximum value and a minimum value among values relating to distances between the respective detected subjects at the respective frames in which the plurality of subjects have been detected and a corresponding imaging unit of the imaging units; an adjusting unit that, if a difference between a range of a specific frame, whose range has been computed by the range computing unit, and a range of a frame captured immediately before or after the specific frame, exceeds a predetermined threshold value, adjusts the range of the specific frame such that the difference is reduced; a parallax amount computing unit that computes a parallax amount corresponding to the range computed by the range computing unit or the range adjusted by the adjusting unit, based on a predetermined relationship between ranges and parallax amounts; a stereoscopic image generation unit that generates a stereoscopic image corresponding to each frame, from a plurality of viewpoint images captured by the respective imaging units, based on the parallax amount computed by the parallax amount computing unit; and a recording control unit that effects control so as to record, at a recording unit, the stereoscopic image generated by the stereoscopic image generation unit, wherein the detection unit determines whether or not a subject that has been detected in a frame immediately before a target frame of detection is detected in the target frame and, based on a result of the determination, the range computing unit performs computation of a range or the adjusting unit performs adjustment of a range.
