Imaging device and display method

Abstract

A finder display processing unit displays a finder image on a finder screen, measures the distance through triangulation from a stereo camera to a part of a subject expressed in a designated region on the finder image, and designates the shortest distance and the farthest distance from the stereo camera to the subject on the basis of the distance acquired through distance measurement. A finder display processing unit specifies as an effective range candidate a range where the imaging ranges of the first imaging unit and a second imaging unit overlap, specifies an effective range candidate at the shortest distance and an effective range candidate at the farthest distance on the first photographed image, and specifies the range where these effective range candidates overlap as the effective range. The finder display processing unit displays on the finder screen information indicating the specified effective range.

Description

[0001] This application is based on the application No. JP Japanese Patent Application No. 2010-58483 filed on March 15, 2010. In this specification, the whole of this specification, a claim, and drawing is taken in by reference. technical field [0002] The present invention relates to an imaging device and a display method suitable for modeling using a stereo camera. Background technique [0003] People often use 3-dimensional (3D) representation of computer graphics and require more realistic 3D representation. In response to such demands, a method of creating 3D modeling data by imaging an actual three-dimensional object with a camera has been established. In this case, for example, as described in JP Unexamined Patent Publication No. 6-3122, in order to recognize the three-dimensional position of a three-dimensional object, a so-called compound eye camera (stereo camera) is used in which a deviation of an optical axis corresponding to parallax is set. ).

Problems solved by technology

In this case, since the modeling data of the part located in the non-overlapping area cannot be formed, it is necessary to re-operate the photography, etc.

[0011] On the other hand, if the error of the depth of field value is set to be smaller than the depth of the subject, the subject is actually contained in the overlapping area, but it is determined that the shape cannot be measured.

In this case, although the original shooting is actually successful, the photographer is forced to perform unnecessary unnecessary work such as rechecking the shooting conditions.

[0012] That is, if the depth of the subject is taken into consideration and an error occurs in the depth of field value, it can be said that the distance measurement accuracy of AF is insufficient, so the above-mentioned problems are notable.

That is, if accurate distance measurement that takes the depth of the subject into consideration is not performed, the identification of the overlapping area will be inaccurate, and as a result, the shooting efficiency will be significantly reduced.
