摘要:
An image processing apparatus generates one image by using at least one frame each of a plurality of moving images obtained by taking moving images of a plurality of different regions of an eye at different times. The apparatus includes a deciding unit configured to decide the at least one frame in each of the plurality of moving images, so that regions which have actually been shot are included in the plurality of moving images in the plurality of regions; and an image generating unit configured to generate one image by using the at least one frames decided from each of the plurality of moving images.

A viewer includes a multifocal lens capable of setting one of a plurality of focal lengths. When a measuring section detects a change in gazing point distance, a selection section selects a focal length to be set among the plurality of focal lengths, and a determiner determines a time duration before a focal length of the multifocal lens is changed. A controller changes the focal length of the multifocal lens when a detector detects a blink or saccadic eye movement of the user before the determined time duration elapses.

A diagnosis supporting device includes a display, an imaging unit configured to capture a subject, an eye gaze detector configured to detect an eye gaze direction of the subject from a captured image captured by the imaging unit, a gaze point detector configured to detect a gaze point of the subject in a display region of the display, based on the eye gaze direction, an output controller configured to display, on the display, a diagnosis image that includes a person image and a geometric pattern image, and in which at least one of contrast, color density, and a degree of transmittance of the person image or the geometric pattern image is changed over time, and an evaluator configured to calculate an evaluation value of the subject, based on the gaze point detected by the gaze point detector when the diagnosis image is displayed.

One aspect of the disclosure includes a method to assess vision function. In one embodiment, the method comprises providing a sequence of test images on a display (106) to a test subject (102) during a stimulus interval and providing a response pattern image for each of the sequence of test images during a response interval after the stimulus interval. Each of the sequence of test images includes multiple stimulus patterns (304, 306) arranged around a fixation target (302). The response pattern image includes multiple response targets (320), each of which corresponds to a location of each of the multiple stimulus patterns (304, 306). One (304) of the multiple stimulus patterns (304, 306) differs. An assessment of a vision function of the test subject (102) is based on a selection by the test subject of one of the multiple response targets (320) that the test subject indicates corresponds to a location of the multiple stimulus pattern that differs (304). A corresponding vision testing system (100) is disclosed as well.

Cognitive function testing. At least some of example embodiments are methods including performing a cognitive function test on a patient without calibrating pupil position of the patient. The performing may include: causing a visual cue on a computer screen in front of the patient to move in a predetermined pattern; reading frames from an eye camera that captures images of an eye of the patient while the visual cue moves on the computer screen and the patient visually tracks the visual cue; determining pupil position within the frames; correcting offsets between the stimulus data and the pupil position data; translating the pupil position data from a coordinate space of the eye camera to a coordinate space of the stimulus data; and generating a test score being the cumulative distance between the stimulus data and pupil position data for each corresponding point in time.

This invention relates to a method for providing markers for evaluating and/or practising the visual field recognizable by an eye, and/or eyes, and/or visual system of a person. The method relies on the reporting of the person of identifications of fixation objects only identifiable when the eye or eyes of the person are accurately fixated on the fixation object. Accordingly active monitoring of a saccade, if a saccade triggering stimulus is employed; or smooth pursuit, if smooth pursuit triggering stimulus is employed, of the eye of the person is not needed for determining whereto to eye or eyes are fixated. The present invention also relates to the use of a system employing the method of the invention. The present invention further relates to a system for the method of the invention and a software product for the system.
