摘要:
A stereoscopic image processing method capable of preventing occurrence of undesirable cutout of image when a stereoscopic combined image is printed out is provided. A stereoscopic combined image can be created and recorded using a digital still camera 1. This stereoscopic combined image is a single image formed by arranging a plurality of view-point images. At first, left view-point image data and right view-point image data are stored in a memory by performing photographing twice. Then, the data of the two images are arranged laterally into a single image. Through this processing, original stereoscopic combined image data is created. Padding areas (dummy areas) are added to the original stereoscopic combined image data at the upper and lower sides thereof. Namely, a processed image containing the original stereoscopic combined image is created.

摘要:
A photographing apparatus has two binocular stereoscopic modes, i.e., one-take photography mode and two-take photography mode. In the two-take photography mode, a 3D image file is generated from left and right monocular images acquired by performing monocular photographing twice, and the 3D image file thus generated is recorded. In the one-take photography mode, a 3D image file is generated from left and right monocular images acquired by performing binocular photographing once, and the 3D image file thus generated is recorded. When the 3D image file is recorded, a homogeneity tag is recorded in 3D metadata, as tag information of the header data portion of the 3D image file. The homogeneity tag is information about the homogeneity of the two monocular images and describes whether the two monocular images have been acquired in the one-take photography mode in which monocular images highly homogeneous are provided, or in the two-take photography mode in which monocular images not so homogeneous are provided. Since the homogeneity tag is recorded in 3D metadata, the 3D image file is treated as a smallest unit of 3D image. The photographing apparatus generates such a 3D image file and records. Further, the photographing apparatus reproduces such a 3D image file.
