    Abstract: An ophthalmologic apparatus which is capable of preferably executing position matching between an eye and optical system is provided. An ophthalmologic apparatus of an embodiment includes an examination optical system, supporting part, driver, two or more imaging parts, analyzer and controller. The examination optical system is used for an examination of the eye. The supporting part supports a face of a subject. The driver moves the examination optical system and the supporting part relatively and three-dimensionally. The two or more imaging parts substantially simultaneously photograph an anterior eye part of the eye from different directions. The analyzer obtains a three-dimensional position of the eye by analyzing two or more photograph images acquired by the two or more imaging parts substantially simultaneously. The controller controls the driver based on the three-dimensional position to relatively move the examination optical system and the supporting part.

  • Publication number: 20180115632
    Abstract: An information delivery system, an information delivery method, an information processing apparatus, and an information processing method is used advantageously to deliver content stream data easily, reliably and inexpensively to the general users. A personal computer prepares a content file and an order form file using software provided by a center system, and transmits the prepared files to the center system over the Internet. Given the order form file from a customer device, the center system encodes a content file accordingly to generate content stream data and causes a moving picture delivery server to deliver the generated stream data to user terminals. This invention can be applied, among others, to systems for delivering content data over the Internet.

    Abstract: An ophthalmologic apparatus capable of performing suitable examination according to the state of the eye includes an examination optical system used to examine an eye, a drive part, two or more imaging parts, an analyzer, and a controller. The drive part moves the examination optical system. The two or more imaging parts substantially simultaneously photograph the anterior segment of the eye from different directions. The analyzer analyzes photographic images captured by the two or more imaging parts to obtain the three-dimensional position of the eye, and displacement information indicating the displacement direction and displacement amount of the eye due to eye movement. The controller performs a first alignment process of controlling the drive part based on the three-dimensional position to move the examination optical system and a second alignment process of controlling the drive part based on the displacement information to move the examination optical system.
