Abstract: An image retrieval apparatus includes a processor, and the processor performs a process including: determining an image in which a first characteristic object is included in a subject to be a first image, and determining an image that is captured after the first image and in which a second characteristic object is included in the subject to be a second image, from among a series of captured images; specifying images as an image group, the images being captured during a period after the first image is captured before the second image is captured from among the series of captured images; and extracting a representative image from the image group.

Abstract: The present invention is a 3-dimensional image capturing method and a 3-dimensional image capturing apparatus for capturing a 3-dimensional image including a left eye image and a right eye image that are 2-dimensional images having parallax with each other. In the invention, an optical axis of an image capturing optical system of the image capturing apparatus is shifted between a first optical axis and a second optical axis whose image capturing ranges overlap at least partly, without moving the image captuing apparatus itself, and in the shift of the optical axis, one of the left eye image and the right eye image is captured at the timing when the optical axis of the image capturing optical system is being the first optical axis, and the other of the left eye image and the right eye image is captured at the timing when the optical axis of the image capturing optical system is being the second optical axis.
