20130188141 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND PROGRAM - To ensure display of a region of interest on a fundus image and a tomographic image of an eye to be inspected in a correspondence manner, an apparatus for processing images of an eye to be inspected includes: a unit that acquires a fundus image of an eye to be inspected; a unit that designates an arbitrary point on the fundus image; a unit that acquires a tomographic image of the eye to be inspected; a unit that calculates a point on the tomographic image corresponding to the arbitrary point; and a unit that converts a coordinate system for displaying the tomographic image and the fundus image in association with each other on the basis of positions of the arbitrary point and the corresponding point. | 07-25-2013 |
20130194094 | OPHTHALMOLOGIC APPARATUS, CONTROL METHOD THEREFORE, AND RECORDING PROGRAM EXECUTING THE METHOD - When an anterior segment photographing mode is selected, ease of operation by an inspector is improved. An ophthalmologic apparatus includes an area changing unit for changing a movement area of an optical unit including an optical path of measuring light, when an anterior segment photographing mode for photographing an anterior segment of an eye to be inspected is selected, to be different from a movement area when a mode other than the anterior segment photographing mode is selected. | 08-01-2013 |
20140063448 | OPHTHALMOLOGIC APPARATUS, CONTROL METHOD FOR OPHTHALMOLOGIC APPARATUS, AND PROGRAM - Provided is an ophthalmologic apparatus capable of efficiently switching between an attitude for packing and an attitude for eye examination. When a USB communication between the ophthalmologic apparatus and a PC for control is disconnected, an attitude of the ophthalmologic apparatus is switched from the attitude for eye examination to the attitude for packing. Even when the USB communication between the ophthalmologic apparatus and the PC for control is established, if there is no operation for a certain period of time, the attitude for eye examination is switched to the attitude for packing. When power of the ophthalmologic apparatus is turned off, the attitude for eye examination is switched to the attitude for packing, using a spare power supply provided to a main body of the ophthalmologic apparatus. | 03-06-2014 |
20140063507 | OPTICAL COHERENCE TOMOGRAPHIC IMAGING APPARATUS AND CONTROL METHOD THEREOF - An optical coherence tomographic imaging apparatus capable of shortening the time required for focus adjustment and reducing the burden on an object is provided. The apparatus includes a first focus unit that moves a first optical focus member disposed in a light-receiving optical system of an optical observation system that obtains an observed image of an object, and a second focus unit that moves a second optical focus member disposed in an optical interference system that acquires a tomographic image of the object in conjunction with a movement of the first optical focus member. | 03-06-2014 |
