Abstract

An electronic apparatus capable of obtaining a good 3D image is provided.
An electronic device acquires a first image by a first shooting and acquires a second image by a second shooting. At this time, the electronic device acquires the inclination (α degree) of the electronic device when the first image is acquired and the inclination (β degree) of the electronic device when the second image is acquired. The electronic device calculates the average ((α + β) / 2) of each inclination of the two images. The electronic device derives the rotated image 410 from the first image and derives the rotated image 420 from the second image. Since both the rotated image 410 and the rotated image 420 are obtained as images that are inclined by (α + β) / 2 degrees from the horizontal direction, if a three-dimensional display using these images is performed, the electronic device is regarded as an image without blurring. Visible to users.

Description

  This disclosure relates to acquisition of an image to be visually recognized as a three-dimensional image, and more specifically to a technique for acquiring data for displaying a three-dimensional image by a plurality of photographing.

  In a conventional three-dimensional (hereinafter also referred to as “3D”) image photographing camera, the distance between the left-eye photographing camera and the right-eye photographing camera is about 6.5 to the average human pupil distance. It was common to set and fix to 7 cm. However, in such a conventional 3D image capturing camera, it is necessary to mount two cameras, and there is a problem that the cost of the entire apparatus including the cameras becomes high.

  In order to solve such a problem, for example, Japanese Patent Laid-Open No. 10-254079 (Patent Document 1) places one camera on a track laid in the horizontal direction and moves the camera along the track. A technique for capturing a 3D image by capturing an image for the left eye and an image for the right eye by capturing the subject twice.

  Japanese Laid-Open Patent Publication No. 2009-103980 (Patent Document 2) continuously captures images at regular time intervals, captures images from stable images during stable panning, and captures images at positions closest to binocular parallax. A pair of images that are panned most smoothly is extracted from the set of images as a pair of images most suitable for a stereoscopic image, and is divided into an image for the left eye and an image for the right eye. The technique of recording is disclosed.

  By the way, 3D image shooting uses a technique common to panoramic image shooting in that two images are shot and combined. Regarding panoramic image shooting, for example, Japanese Patent Laid-Open No. 2011-114802 (Patent Document 3) uses the tilt data acquired by the tilt detection unit to match the tilt of the next captured image with the tilt of the image captured immediately before. By doing so, a technique for photographing a panoramic image in which the boundary portion between two images is clearly connected is disclosed. Japanese Patent Laid-Open No. 11-352568 (Patent Document 4) discloses a technique for generating a panoramic photograph without naturalness at a joint by making the photographer aware of the inclination of the composition.

  Japanese Patent Laying-Open No. 2010-239564 (Patent Document 5) discloses a technique for acquiring a highly accurate 3D model.

In that case, when the difference in inclination is not within the predetermined range, the image for the left eye and the image for the right eye are not adopted as images for creating a 3D image. Therefore, depending on the person who operates the camera, an image for the left eye and an image for the right eye for creating a 3D image having an appropriate stereoscopic effect may not be easily acquired.

  According to the technique disclosed in Patent Document 3, when the inclination of the image obtained by the next photographing is matched with the inclination of the image obtained by the immediately preceding photographing, the difference between the two images is large. Requires a significant rotation of the second image taken. However, by rotating the image significantly, the image area that is cut when the two images are combined (that is, the area that does not overlap in the two images) becomes large, and an effective rectangle necessary for the image combination There was a problem that the area became smaller.

Accordingly, it can be said that the essential part of the present invention is software stored in the RAM 4, the hard disk 5, the CD-ROM 9, or other data recording medium, or software that can be downloaded via a network. Since the operation of each hardware of computer system 1500 is well known, detailed description will not be repeated.

  The data recording medium is not limited to a CD-ROM, FD (Flexible Disk), and hard disk, but is a magnetic tape, cassette tape, optical disk (MO (Magnetic Optical Disc) / MD (Mini Disc) / DVD (Digital Versatile Disc)). ), IC (Integrated Circuit) card (including memory card), optical card, mask ROM, EPROM (Electronically Programmable Read-Only Memory), EEPROM (Electronically Erasable Programmable Read-Only Memory), semiconductor memory such as flash ROM, etc. It may be a medium that carries the program in a fixed manner.

  The program here may include not only a program directly executable by the CPU but also a program in a source program format, a compressed program, an encrypted program, and the like.

<Effect of Embodiment>
As described above, according to mobile phone 500 according to the present embodiment, it is possible to obtain a good three-dimensional image with less blur when two shootings are performed.

  That is, according to the present embodiment, the left eye image and the right eye image are photographed by moving one camera in the horizontal direction and photographing twice, and the two photographed images are obtained. The quality of a 3D image obtained by a camera that creates a 3D image by combining them into one sheet can be improved. Even if the angle with respect to the horizontal direction of the image obtained by the first shooting and the angle with respect to the horizontal direction of the image obtained by the second shooting change due to camera shake at the time of shooting, a 3D image having an appropriate stereoscopic effect is obtained. Can be created. At that time, by rotating the two images with each other, an effective rectangular area necessary for synthesizing the images obtained by photographing to obtain a 3D image can be enlarged.

  Note that although the mobile phone 500 including one camera is illustrated in this embodiment, the application of the technical idea according to this embodiment is not limited to an electronic device having such a configuration. For example, in a smartphone with two cameras, if one of the cameras is broken or if the camera lens is dirty, only the other camera that is effective for shooting is used. A configuration in which data for 3D images is acquired by prompting the user of the smartphone for the second shooting may be applied.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
