STEREOSCOPIC SHOOTING DEVICE
First Claim
1. A stereoscopic shooting device comprising:
- a first shooting section having a zoom optical system and being configured to obtain a first image by shooting a subject;
a second shooting section configured to obtain a second image by shooting the subject; and
an angle of view matching section configured to cut respective image portions that would have the same angle of view out of the first and second images, the angle of view matching section including;
a vertical area calculating section configured to select a plurality of mutually corresponding image blocks that would have the same image feature from the first and second images and calculate a vertical image area of the second image that would have the same vertical direction range as the first image based on relative vertical positions of the image blocks in the respective images;
a number of horizontal lines matching section configured to adjust the number of horizontal lines included in the vertical image area of the second image that has been calculated by the vertical area calculating section and the number of horizontal lines included in the first image to a predetermined value and then output a signal representing the horizontal lines included in the first image as a first horizontal line signal and a signal representing the horizontal lines included in the vertical image area of the second image as a second horizontal line signal, respectively; and
a horizontal matching section configured to carry out stereo matching by comparing to each other the first and second horizontal line signals supplied from the number of horizontal lines matching section,wherein the vertical area calculating section is configured to determine the vertical image area by comparing the ratio of the vertical coordinates of respective representative points in a plurality of image blocks selected from the first image to the ratio of the vertical coordinates of respective representative points in a plurality of image blocks selected from the second image.

Abstract
A stereoscopic shooting device includes: a first and second shooting sections that obtain a first and second images, respectively; and an angle of view matching section. The angle of view matching section performs: calculating a vertical image area of the second image that has the same vertical direction range as the first image by comparing ratios of the vertical coordinates of respective representative points in image blocks selected from the first and second images, respectively; adjusting the number of horizontal lines included in the vertical image area of the second image and the number of horizontal lines included in the first image; outputting a first and second horizontal line signals representing the horizontal lines included in the first image and the vertical image area of the second image, respectively; and carrying out stereo matching by comparing the first and second horizontal line signals to each other.
